Accordingly, the invention expressly should not be limited to such exemplary embodiments illustrating some possible non-limiting combination of features that may exist alone or in other combinations of features; the scope of the invention being defined by the claims appended hereto. 
     Referring to  FIG. 1 , a product array  1000  will be described in accordance with one embodiment of the present invention. In the exemplified embodiment, the product array  1000  comprises a first oral care kit  110 , a second oral care kit  130 , and a third oral care kit  150 . 
     Although three oral care kits are depicted in this embodiment, the product array  1000  may include any number of oral care kits in other embodiments as desired depending on the amount of variation in the product array. Thus, the product array  1000  may include two oral care kits in some embodiments and more than three oral care kits in other embodiments. 
     In the exemplified embodiment, the first oral care kit  110  comprises a first oral care material  111  that provides a first oral care benefit to a user during use thereof. The first oral care kit  110  also comprises a first toothbrush  112  that comprises a first plurality of tooth cleaning elements  113 . The first plurality of tooth cleaning elements  113  includes at least one first type of tooth cleaning element  114 . The at least one first type of tooth cleaning element  114  also provides the first oral care benefit to the user during use of the first toothbrush  112 . Thus, the first oral care material  111  and the first type of tooth cleaning element  114  provide the same first oral care benefit to a user. Finally, the first oral care kit  110  also includes a first package  115  that contains the first oral care material  111  and the first toothbrush  112 . 
     The second oral care kit  130  comprises a second oral care material  131  that provides a second oral care benefit to a user during use thereof. The second oral care benefit may, in certain embodiments, be different than the first oral care benefit. The second oral care kit  130  also comprises a second toothbrush  132  that comprises a second plurality of tooth cleaning elements  133 . The second plurality of tooth cleaning elements  133  includes at least one second type of tooth cleaning element  134 . The at least one second type of tooth cleaning element  134  also provides the second oral care benefit to the user during use of the second toothbrush  132 . Thus, the second oral care material  131  and the second type of tooth cleaning element  134  provide the same second oral care benefit to a user. Finally, the second oral care kit  130  also includes a second package  135  that contains the second oral care material  131  and the second toothbrush  132 . 
     The third oral care kit  150  comprises a third oral care material  151  that provides a third oral care benefit to a user during use thereof. In certain embodiments, the third oral care benefit may be different than each of the first and second oral care benefits. The third oral care kit  150  also comprises a third toothbrush  152  that comprises a third plurality of tooth cleaning elements  153 . The third plurality of tooth cleaning elements  153  includes at least one third type of tooth cleaning element  154 . The at least one third type of tooth cleaning element  154  also provides the third oral care benefit to the user during use of the third toothbrush  152 . Thus, the third oral care material  151  and the third type of tooth cleaning element  154  provide the same third oral care benefit to a user. Finally, the third oral care kit  150  also includes a third package  155  that contains the third oral care material  151  and the third toothbrush  152 . 
     Thus, in each of the first, second, and third oral care kits  110 ,  130 ,  150 , one of the first, second, and third oral care materials  111 ,  131 ,  151  is placed together in the respective kit with the one of the first, second, and third types of tooth cleaning elements  114 ,  134 ,  154  that provides the same oral care benefit as the oral care material in that particular kit. Specifically, the first, second, and third oral care materials  111 ,  131 ,  151  may be one of a tooth whitening agent that has an oral care benefit of tooth whitening to a user during use, a tooth anti-sensitivity agent that has an oral care benefit of treating a user&#39;s sensitive teeth, a breath freshening agent that has an oral care benefit of freshening a user&#39;s breath, and an anti-bacterial agent that has an oral care benefit of treating bacteria in a user&#39;s mouth. Furthermore, the first, second, and third types of tooth cleaning elements  114 ,  134 ,  154  may be selected from spiral bristles or elastomeric tooth cleaning elements, both of which have the oral care benefit of tooth whitening, tapered bristles or end-rounded bristles having a diameter of 5 mils or less, both of which have the oral care benefit of tooth anti-sensitivity, charcoal bristles that have the oral care benefit of oral malodor treatment, and bristles containing an anti-bacterial additive (such as silver zeolite) that has the oral care benefit of being anti-bacterial. 
     Referring specifically to the embodiment exemplified in  FIG. 1 , in the first kit  110  the first oral care material  111  is an anti-sensitivity agent and the first type of tooth cleaning element  114  is a tapered bristle. In certain embodiments, all of the tooth cleaning elements in the first kit  110  need not be of the first type of tooth cleaning element  114 , but rather at least one of the tooth cleaning elements in the first kit  110  is of the first type of tooth cleaning element  114 . More specifically, in certain embodiments at least one tuft of the tooth cleaning elements consists of the first type of tooth cleaning elements  114 , and in some embodiments multiple tufts of the tooth cleaning elements consist of the first type of tooth cleaning elements  114  while others of the tufts of tooth cleaning elements contain cleaning elements that are not of the first type. It is appropriate to include the anti-sensitivity agent and the tapered bristle together in the first kit  110  because both anti-sensitivity agents and tapered bristles provide the same oral care benefit of treating tooth sensitivity. 
     Furthermore, in the second kit  130  the second oral care material  131  is an anti-bacterial agent and the second type of tooth cleaning element  134  is a bristle containing an anti-bacterial additive. All of the tooth cleaning elements in the second kit  130  need not be of the second type of tooth cleaning element  134 , but rather at least one of the tooth cleaning elements in the second kit  130  is of the second type of tooth cleaning element  134 . More specifically, in certain embodiments at least one tuft of the tooth cleaning elements consists of the second type of tooth cleaning elements  134 , and in some embodiments multiple tufts of the tooth cleaning elements consist of the second type of tooth cleaning elements  134  while others of the tufts of tooth cleaning elements contain cleaning elements that are not of the second type. It is appropriate to include the anti-bacterial agent and the bristle containing an anti-bacterial additive together in the second kit  130  because both anti-bacterial agents and bristles containing an anti-bacterial additive provide the same oral care benefit of being anti-bacterial or treating bacteria in a user&#39;s mouth. 
     Moreover, in the third kit  150  the third oral care material  151  is a tooth whitening agent and the third type of tooth cleaning element  154  is a spiral bristle. All of the tooth cleaning elements in the third kit  150  need not be of the third type of tooth cleaning element  154 , but rather at least one of the tooth cleaning elements  154  in the third kit  150  is of the third type of tooth cleaning element  154 . More specifically, in certain embodiments at least one tuft of the tooth cleaning elements consists of the third type of tooth cleaning elements  154 , and in some embodiments multiple tufts of the tooth cleaning elements consist of the third type of tooth cleaning elements  154  while others of the tufts of tooth cleaning elements contain cleaning elements that are not of the third type. It is appropriate to include the tooth whitening agent and the spiral bristle together in the third kit  150  because both tooth whitening agents and spiral bristles provide the same oral care benefit of tooth whitening. The manner of pairing oral care materials with types of tooth cleaning elements within each kit of the product array  1000  will be described in more detail below. 
     In  FIG. 1 , the various components of each of the kits  110 ,  130 ,  150  are illustrated schematically for simplicity. The package  115 ,  135 ,  155  may be any type of package that is commonly used to package oral care merchandise. For example, the package  115 ,  135 ,  155  may be the type that has a cardboard backer panel and a three-dimensional transparent plastic cover such that the merchandise (i.e., toothbrushes  113 ,  133 ,  153  and oral care material  111 ,  131 ,  151 ) is positioned within a cavity formed between the backer panel and the cover. In other embodiments, the package  115 ,  135 ,  155  may be a sealed plastic container that is either rigid or non-rigid (i.e., plastic bag). In still other embodiments, the package  115 ,  135 ,  155  may be omitted and the oral care material  111 ,  131 ,  151  and toothbrush  112 ,  132 ,  152  may be coupled together to form the kits  110 ,  130 ,  150 . Thus, the invention is not intended to be limited by the specific details of the package  115 ,  135 ,  155  in all embodiments, but rather it is to be understood that the package  115 ,  135 ,  155  may be any mechanism for grouping a toothbrush and an oral care material together in a kit for retail. Furthermore, the toothbrushes  112 ,  132 ,  152  within each kit  110 ,  130 ,  150  are generically illustrated and may have various contours, shapes, sizes, colors, and the like. In certain embodiments it is preferable that the toothbrushes  112 ,  132 ,  152  are all structurally identical except with regard to the included type of tooth cleaning element that provides one of the oral care benefits described herein. Of course, the invention is not to be so limited and the toothbrushes  112 ,  132 ,  152  may be different from one another in some aspects in other embodiments. 
     Referring to  FIGS. 2A-2C , a method of forming a product array of a plurality of oral care kits will be described.  FIG. 2A  illustrates a plurality of different types of tooth cleaning elements, including an end-rounded bristle with a diameter of 5 mils or less  201 , a tapered bristle  202 , a charcoal bristle  203 , an elastomeric tooth cleaning element  204 , a bristle containing an anti-bacterial agent  205 , and a spiral bristle  206 .  FIG. 2B  schematically illustrates a plurality of different types of oral care materials, including an anti-sensitivity agent  211 , an anti-bacterial agent  212 , a breath freshening agent  213 , and a tooth whitening agent  214 . Although the above-mentioned types of agents are used in the description, the invention is not to be so limited in all embodiments and the types of oral care materials may include fluoride, tartar protection agents, oxidative agents, enamel strengthening or repair agents, tooth erosion preventing agents, a gum health active, a nutritional ingredient, a tartar control or anti-stain ingredient, an enzyme, a sensate ingredient, a flavor or flavor ingredient, an oral malodor reducing agent, an anti-attachment agent or sealant, a diagnostic solution, an occluding agent, a dry mouth relief ingredient, a catalyst to enhance the activity of any of these agents, colorants or aesthetic ingredients, arginine bicarbonate, chlorohexidine, triclosan, CPC, zinc oxide and combinations thereof. In certain embodiments, the oral care material may be free of a dentifrice as the oral care material is intended to supplement traditional brushing of the teeth rather than supplant it. 
       FIG. 2C  illustrates a first toothbrush  221  and a second toothbrush  222 , each depicted without bristles or tooth cleaning elements. The first toothbrush  221  has a head portion  222  and a handle portion  223  and the second toothbrush  225  has a head portion  226  and a handle portion  227 . Each of the first and second toothbrushes  221 ,  225  is structurally identical at this stage of the method. To form the product array, a first one of the oral care materials  211 - 214  that provides a first oral care benefit and a second one of the oral care material  211 - 214  that provides a second oral care benefit are selected, with the first and second oral care materials  211 - 214  and the first oral care benefit and the second oral care benefit being different from one another. After selection of the first and second oral care materials, the next step is to select a first type of the tooth cleaning elements  201 - 206  that provides the first oral care benefit to place in a kit with the first one of the oral care materials  211 - 214  and a second type of the tooth cleaning elements  201 - 206  that provides the second oral care benefit to place in a kit with the second one of the oral care materials  211 - 214 . 
     If the first one of the oral care materials that is selected is the anti-sensitivity agent  211 , it is known that the first oral care benefit is tooth anti-sensitivity. When selecting the first type of tooth cleaning elements that will be coupled to the toothbrush that forms a kit with the selected first one of the oral care materials (the anti-sensitivity agent), the tooth cleaning element that shares the first oral care benefit of treating bacteria will be selected. Therefore, in this example, the first type of tooth cleaning element will either be the tapered bristle  202  or the end-rounded bristle having a diameter of 5 mils or less  201  because both of those types of tooth cleaning elements have a benefit of tooth anti-sensitivity. 
     Similarly, if the second one of the oral care materials that is selected is the tooth whitening agent  214 , it is known that the second oral care benefit is tooth whitening. When selecting the second type of tooth cleaning elements that will coupled to the toothbrush that forms a kit with the second one of the oral care materials (the tooth whitening agent), the tooth cleaning element that shares the second oral care benefit of tooth whitening will be selected. Therefore, in this example the second type of tooth cleaning element will either be the spiral bristle  206  or the elastomeric tooth cleaning element  204  because both of those types of tooth cleaning elements have a tooth whitening benefit. 
     Of course, if the anti-bacterial agent  212  is selected, then the bristle containing an anti-bacterial additive  205  will be selected and if the breath freshening agent  213  is selected the charcoal bristle  203  will be selected. Thus, in forming the product array  1000 , the type of tooth cleaning element selected will have the same oral care benefit as the oral care material that the toothbrush that the tooth cleaning element is coupled to will be paired with in a kit. Although in the above description the oral care material is selected first, the invention is not to be so limited and the type of tooth cleaning element may be selected first, followed by selecting the oral care material that shares the same oral care benefit therewith. 
     After the types of tooth cleaning elements are selected, a first plurality of tooth cleaning elements are coupled to the head portion  222  of the first toothbrush  221 . The first plurality of tooth cleaning elements will comprise at least one of the first type of tooth cleaning elements, which in the example above is either the tapered bristle  202  or the end-rounded bristle having a diameter of 5 mils or less  201  (or one or more of each of the tapered bristle  202  and the end-rounded bristle  201 ). Thus, the first plurality of tooth cleaning elements need not comprise only the first type of tooth cleaning elements, but may instead include some of the first type of tooth cleaning elements along with other tooth cleaning elements. The first type of tooth cleaning elements may be clustered together to form a tuft that comprises only the first type of tooth cleaning elements, or the first type of tooth cleaning elements may be included in tufts with other types of tooth cleaning elements. 
     Similarly, a second plurality of tooth cleaning elements are coupled to the head portion  226  of the second toothbrush  225 . The second plurality of tooth cleaning elements will comprise at least one of the second type of tooth cleaning elements, which in the above example is either the spiral bristle  206  or the elastomeric tooth cleaning element  204 . Thus, the second plurality of tooth cleaning elements need not comprise only the second type of tooth cleaning elements, but may instead include some of the second type of tooth cleaning elements along with other tooth cleaning elements. The second type of tooth cleaning elements may be clustered together to form a tuft that comprises only the second type of tooth cleaning elements, or the second type of tooth cleaning elements may be included in tufts with other types of tooth cleaning elements. 
     Thus, the plurality of tooth cleaning elements may include the selected type of tooth cleaning element along with any other variety of tooth cleaning elements mounted on the head portions  222 ,  226  of the toothbrushes  221 ,  225 . These other tooth cleaning elements refers to any structure that can be used to clean, polish, or wipe the teeth and/or soft oral tissue (e.g. tongue, cheek, gums, etc.) through relative surface contact. Common examples of tooth cleaning elements include, without limitation, bristle tufts, filament bristles, fiber bristles, nylon bristles, spiral bristles, rubber bristles, elastomeric protrusions, flexible polymer protrusions, combinations thereof and/or structures containing such materials or combinations. Suitable elastomeric materials include any biocompatible resilient material suitable for uses in an oral hygiene apparatus. To provide optimum comfort as well as cleaning benefits, the elastomeric material of the tooth cleaning element may have a hardness property in the range of A8 to A25 Shore hardness. One suitable elastomeric material is styrene-ethylene/butylene-styrene block copolymer (SEBS) manufactured by GLS Corporation. Nevertheless, SEBS material from other manufacturers or other materials within and outside the noted hardness range could be used. 
     Furthermore, the tooth cleaning elements may be mounted to the head portions  222 ,  226  of the toothbrushes  221 ,  225  in any manner known in the art. For example, the tooth cleaning elements can be mounted to the head portions  222 ,  226  using staples/anchors. Alternatively, techniques such as in-mold tufting, anchor free tufting (“AFT”), or AMR can be used to mount the tooth cleaning elements to the head portions  222 ,  226 . One example of mounting tooth cleaning elements to a head of a toothbrush using AFT will be described in detail below with reference to  FIGS. 3A-3D . 
     After the first plurality of tooth cleaning elements that includes at least one of the first type of tooth cleaning element are mounted to the head portion  222  of the first toothbrush  221  and the second plurality of tooth cleaning elements that includes at least one of the second type of tooth cleaning elements are mounted to the head portion  226  of the second toothbrush  225 , the oral care kits are formed. Specifically, a first oral care kit is formed that comprises the first oral care material and the first toothbrush  221  with the first plurality of tooth cleaning elements mounted thereon (and including at least one of the first type of tooth cleaning element) and a second oral care kit is formed that comprises the second oral care material and the second toothbrush  225  with the second plurality of tooth cleaning elements mounted thereon (and including at least one of the second type of tooth cleaning element). The kits may be provided in a package as described above with reference to  FIG. 1  or otherwise as described herein. 
     Referring now to  FIGS. 3A-3D , one method of mounting tooth cleaning elements to a head portion of a toothbrush will be described. Although the method is described herein below with reference to one of the toothbrushes, it should be appreciated that the description set forth herein below may be used for coupling the tooth cleaning elements to each of the toothbrushes in the product array. In the exemplified embodiment, a first head plate  301  is formed, then a first plurality of tooth cleaning elements  350  are coupled to the first head plate  301  to form a first cleaning element assembly  370 . Next, the first cleaning element assembly  370  is coupled to a first head portion  391  of a first toothbrush  390 . The specifics of this technique are set forth below. 
     Referring to  FIG. 3A , the first head plate  301  is illustrated after formation thereof, but before any tooth cleaning elements or other materials are added and/or connected to the first head plate  301 . In certain embodiments the first head plate  301  is formed by an injection molding technique, although other techniques may be used. More specifically, to form the first head plate  301  a mold having a mold cavity in the shape of the first head plate  301  is filled with a molten plastic material. The molten plastic material is then cooled and allowed to harden. Upon hardening, the first head plate  301  is formed and is removed from the mold cavity of the mold. Although the first head plate  301  and the base structure of the first toothbrush  390  can be formed of the same material, the first head plate  301  is a completely separate structure from the base structure of the first toothbrush  390 . 
     The first head plate  301  comprises a front surface  302  and an opposing rear surface  303 . Furthermore, the first head plate  301  comprises a plurality of openings  304  formed therethrough that extend from the front surface  302  to the rear surface  303 . The plurality of openings  304  provide locations at which tooth cleaning elements can be inserted during creation of the first cleaning element assembly  370  as described below. Only some of the openings  304  are labeled in the drawings in order to avoid clutter. 
     Referring to  FIG. 3B , forming the first cleaning element assembly  370  from the first head plate  301  and a first plurality of tooth cleaning elements  350  will be described. As described above, the first plurality of tooth cleaning elements  350  will include at least one of the selected type of tooth cleaning element. In the exemplified embodiment, the selected type of tooth cleaning element is a tapered bristle  305  that provides the oral care benefit of tooth anti-sensitivity. However, the selected type of tooth cleaning element may be any of the other types of tooth cleaning elements described above and illustrated in  FIG. 2A  depending on the type of oral care material that the first toothbrush  390  will be placed together with to form a kit. Although the tapered bristle  305  appears as a single tapered bristle  305  (or a tapered tuft), the invention is not to be so limited and the tuft may include a plurality of tapered bristles or a combination of tapered bristles and other tooth cleaning elements as desired. 
     To couple the first tooth cleaning elements  350  to the first head plate  301 , the first tooth cleaning elements  350  are inserted through the openings  304  in the first head plate  301  so that anchor portions  351  of the first tooth cleaning elements  350  are adjacent to the rear surface  303  of the first head plate  301  and first portions  352  of the first tooth cleaning elements  350  extend from the front surface  302  of the first head plate  301 . After positioning the first tooth cleaning elements  350  within the openings  304  of the first head plate  301 , a heated plate or iron is placed into contact with or adjacent to the anchor portions  351  of the first tooth cleaning elements  350  to melt the anchor portions  351  of the first tooth cleaning elements  350  and form a melt matte  353 . Melting the anchor portions  351  of the first tooth cleaning elements  350  causes the anchor portions  351  of the first tooth cleaning elements  350  to fuse together to form the melt matte  353  adjacent to the rear surface  303  of the first head plate  301 . Thus, the melt matte  353  may be considered a bristle melt, such that the melt matte  353  is formed by melting the anchor portions  351  of the first tooth cleaning elements  350  and then enabling the melted anchor portions  351  to cool and solidify. Thus, the melt matte  353  is essentially a thin layer of the bristle material that is located on or adjacent to the rear surface  303  of the first head plate  301 . Once the first tooth cleaning elements  350  are coupled to or mounted on the first head plate  301  in this manner, the first cleaning element assembly  370  is formed. 
     Referring to  FIG. 3C , after formation, the first cleaning element assembly  370  is positioned adjacent to the first head portion  391  of the first toothbrush  390 . In embodiments that use this technique for mounting the first tooth cleaning elements  350  to the first toothbrush  390 , the first head portion  391  of the first toothbrush  390  comprises a basin  392  for receiving the first cleaning element assembly  370 . The first cleaning element assembly  370  is then positioned into the basin  392  of the first head portion  391  of the first toothbrush  390  and attached thereto. The first cleaning element assembly  370 , and specifically the first head plate  301 , can be attached to the first head portion  391  of the first toothbrush  392  by fusing the first head plate  301  to the first head portion  391  of the first toothbrush  392 . The term fusing includes ultrasonic welding, thermal welding, sonic welding, melting, and thermal fusion. Other techniques for securing the first head plate  301  to the first head portion  391  of the first toothbrush  392  include tight fit, interference fit, snap-fit threaded engagement, adhesion, fasteners, or the like. As best seen in  FIG. 3D , when the first cleaning element assembly  370  is coupled to the first head portion  391  of the first toothbrush  392 , the melt matte  353  is sandwiched between the rear surface  303  of the first head plate  301  and a floor  394  of the basin  392 . 
       FIGS. 3A-3D  illustrate the technique for forming the first cleaning element assembly  370  and coupling the first cleaning element assembly  370  to the first head portion  391  of the first toothbrush  390 . In the embodiment of  FIGS. 3A-3D , the first plurality of cleaning elements  350  include tapered bristles  305  and other tooth cleaning elements. Thus the first toothbrush  390  of  FIGS. 3A-3D  would be packaged together with an oral care material that is an anti-sensitivity agent because both tapered bristles and anti-sensitivity agents provide an oral care benefit of tooth anti-sensitivity. 
     Referring briefly to  FIG. 4 , a second toothbrush  490  having a second head portion  491  with a second basin  492  formed therein is illustrated. Furthermore, a second head plate  401  having a second plurality of tooth cleaning elements  450  mounted thereon (a second cleaning element assembly  470 ) is coupled to the second head portion  491  of the second toothbrush  490  within the second basin  492 . The manner of coupling the second plurality of tooth cleaning elements  450  to the second head plate  401  and of coupling the second head plate  401  to the second head portion  491  of the second toothbrush  490  is the same as that described above with reference to  FIGS. 3A-3D  and will not be repeated herein in the interest of brevity. 
     The main distinction between  FIG. 4  and  FIGS. 3A-3D  is that in  FIG. 4 , the second plurality of tooth cleaning elements  450  does not include tapered bristles, but rather includes spiral bristles  405 . Thus, except for the inclusion of spiral bristles  405  instead of tapered bristles, the second toothbrush  490  is structurally identical to the first toothbrush  390 . In this regard, the second toothbrush  390  of  FIG. 4  would be packaged together with an oral care material that is a tooth whitening agent because both spiral bristles and tooth whitening agents provide an oral care benefit of tooth whitening. 
     In this manner, a large amount of the toothbrushes can be formed that are structurally identical in shape and structure. Then, various cleaning element assemblies can be coupled to the toothbrushes in the manner described above with regard to  FIGS. 3A-3D . The cleaning element assemblies may include different bristle patterns or different special types of tooth cleaning elements (selected from end-rounded with diameter of 5 mils or less, tapered, charcoal, elastomeric, bristle with anti-bacterial additive, and spiral). Specifically, while one cleaning element assembly may include one or more spiral bristles, another cleaning element assembly may include one or more tapered bristles and another cleaning element assembly may include one or more charcoal bristles. The various toothbrushes can then be paired, based on the type of bristles used on the cleaning element assembly, with one of the oral care materials to form a kit so that the type of bristles and the oral care materials forming each respective kit impart the same oral care benefit during use. 
     In certain embodiments, the various toothbrushes can be formed and various cleaning element assemblies with various tooth cleaning element types and patterns can be formed. The cleaning element assemblies may have the same size and shape, and each of the toothbrushes may have a basin with the same size and shape. Thus, the particular cleaning element assembly can be selected for coupling to the toothbrush based on the oral care material that will be paired with that toothbrush to form a kit. Thus, rather than just changing out some bristles, in certain embodiments entirely different bristle patterns including different types of tooth cleaning elements may be used depending on the oral care material paired with the particular toothbrush to form the kit. This is because some bristle patterns may be better suited for tooth whitening while other bristle patterns may be better suited for tooth anti-sensitivity, oral malodor treatment, or anti-bacterial treatment. 
     Referring now to  FIGS. 5A-5C , one particular embodiment of an oral care system  500  is illustrated and will be described. To form a product array, a plurality of the oral care systems  500  can be packaged separately to form oral care kits (as described above with reference to  FIG. 1 ), and the plurality of kits collectively form the product array. Each of the oral care systems  500  may include different combinations of types of tooth cleaning elements and oral care materials. Specifically, similar to the discussion above, each oral care system  500  will have a toothbrush  510  with a type of tooth cleaning element mounted thereon that imparts a specific oral care benefit and a dispenser  560  containing an oral care material that provides the same oral care benefit as the type of tooth cleaning element mounted on the toothbrush  510 . 
     In this embodiment, the toothbrush  510  comprises a handle portion  511  and a head portion  512 . The head portion  512  may include a basin as was described above so that a cleaning element assembly  570  comprising a head plate  571  and a plurality of tooth cleaning elements  572  coupled to the head plate  571  can be attached to the head portion  512  of the toothbrush  510 . The discussion of  FIGS. 3A-3D  above with regard to this process is applicable to this embodiment. The plurality of tooth cleaning elements  572  will include at least one cleaning element that is selected from the various types of cleaning elements illustrated in  FIG. 2A  and described above. 
     The handle portion  511  of the toothbrush  510  comprises a cavity  513 . In the exemplified embodiment, the cavity  513  provides a location into which the dispenser  560  can be positioned for detachably coupling the dispenser  560  to the toothbrush  510 . In certain other embodiments the cavity  513  may be an enclosed cavity that forms a reservoir for storing product such as oral care material. Thus, in some embodiments the dispenser  560  may be omitted and the oral care material may be located directly in the cavity  513  of the handle portion  511  of the toothbrush  510 . 
     In the exemplified embodiment the dispenser  560  can transition between a first position ( FIG. 5A ) wherein the dispenser  560  is located within the cavity  513  of the toothbrush  510  and detachably coupled to the toothbrush  510  and a second position ( FIG. 5B ) wherein the dispenser  560  is removed from the cavity  513  and is separated from the toothbrush  510 . The first position may be a storage position such that the dispenser  560  is stored within the cavity  513  of the toothbrush  510  during periods of time that the dispenser  560  is not being used to dispense product into a user&#39;s oral cavity. The second position may be a use position such that an applicator  561  of the dispenser  560  is exposed for dispensing product (i.e., an oral care material) into a user&#39;s oral cavity. 
     The dispenser  560  forms a housing having a reservoir  562  that stores an oral care material  563 , such as any of the different types of oral care material described herein with reference to  FIG. 2B . The reservoir  562  can be filled with any of the oral care materials described above (i.e., tooth anti-sensitivity agent, tooth whitening agent, breath freshening agent, anti-bacterial agent, or the like) and the dispenser  560  can be paired together to form a kit with a toothbrush  510  that includes a tooth cleaning element that imparts the same oral care benefit as the oral care material stored in the reservoir  562  of the dispenser  560 . 
     The dispenser  560  may include a dispensing mechanism  565  to facilitate dispensing of the oral care material  563  from the reservoir  562  into a user&#39;s oral cavity for treatment thereof. In the exemplified embodiment, the dispensing mechanism  565  is an elevator mechanism  566  that is operably coupled to an actuator  567  such that actuating the actuator  567  causes the elevator mechanism  566  to move within the reservoir  562 , thereby causing the oral care material  563  to be dispensed. The dispenser  560  includes a dispensing orifice  568  that provides a point of egress for the oral care material  563  to be dispensed from the reservoir  562 . The applicator  561  may be formed of a thermoplastic elastomer and may be configured for direct contact with a user&#39;s teeth and oral surfaces for direct application of the oral care material. In the exemplified embodiment the applicator  561  includes a plurality of nubs  569 , although the invention is not to be so limited in all embodiments and the nubs  569  (and even the applicator entirely) may be omitted in some embodiments. 
     In certain embodiments, the method of forming the product array includes providing a selected first oral care material that provides a first oral care benefit into the reservoir  562  of a first one of the dispensers  560 . The method than includes detachably coupling the first one of the dispensers  560  to a first one of the toothbrushes  510  that comprises a first type of tooth cleaning element that provides the same first oral care benefit as the first oral care material, thereby forming a first oral care system  500  that includes the first one of the toothbrushes  510  and the first one of the dispensers  560 . Finally, the method includes packaging the first oral care system  500  in a first package to form a first oral care kit. In one specific non-limiting embodiment the first oral care material is a tooth whitening agent and the first type of tooth cleaning element is a spiral bristle. 
     Furthermore, the method includes providing a selected second oral care material that provides a second oral care benefit into the reservoir  562  of a second one of the dispensers  560 . The method then includes detachably coupling the second one of the dispensers  560  to a second one of the toothbrushes  510  that comprises a second type of tooth cleaning element that provides the same second oral care benefit as the second oral care material thereby forming a second oral care system  500 . Finally, the method includes packaging the second oral care system  500  in a second package to form a second oral care kit. In one specific non-limiting embodiment the second oral care material is a tooth anti-sensitivity agent and the second type of tooth cleaning element is a tapered bristle or an end-rounded bristle having a diameter of 5 mils or less. 
     In certain embodiments the kits may be formed by packaging one of the dispensers  560  and one of the toothbrushes  510  in a package without first detachably coupling the dispenser  560  to the toothbrush  510 . Thus, in certain embodiments the step of detachably coupling the dispenser  560  to the toothbrush  510  before packaging is optional, and the dispenser  560  and the toothbrush  510  may be packaged together so that both are visible and the dispenser  560  is not hidden from view by being located within the cavity  513  of the toothbrush  510 . 
     As described above, the oral care material  563  may be a tooth whitening agent, an anti-bacterial agent, a tooth anti-sensitivity agent, a breath freshening agent, or the like as may be desired. Furthermore, the type of tooth cleaning elements that are included with the plurality of tooth cleaning elements  572  may be selected so that at least one of the plurality of tooth cleaning elements is of a type that imparts the same benefit as the oral care material  563  that is disposed within the reservoir  563 . 
     Thus for example, if the oral care material  563  in the kit is a tooth whitening agent, at least one of the tooth cleaning elements  572  on the toothbrush in the kit would be a spiral bristle or an elastomeric tooth cleaning element to provide a benefit of tooth whitening. If the oral care material  563  in the kit is an anti-sensitivity agent, at least one of the tooth cleaning elements  572  on the toothbrush in the kit would be a tapered bristle or an end-rounded bristle having a diameter of 5 mils or less to provide a benefit of anti-sensitivity. If the oral care material  563  in the kit is a breath freshening agent, at least one of the tooth cleaning elements  572  on the toothbrush in the kit would be a charcoal bristle to provide a benefit of treating oral malodor. Finally, if the oral care material  563  in the kit is an anti-bacterial agent, at least one of the tooth cleaning elements  572  on the toothbrush in the kit would be a bristle containing an anti-bacterial additive (such as silver zeolite) to provide a benefit of anti-bacterial treatment.
