## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application No. 61/589,485, filed Jan. 23, 2012, and U.S. Provisional Application No. 61/703,764, filed Sep. 20, 2012, the contents of each of which are hereby incorporated by reference in their entirety.


TECHNICAL FIELD
The present invention relates generally to appliances for orthodontic hardware and/or teeth. More specifically, the present invention relates to devices, systems and methods for shielding orthodontic hardware and/or deficiencies in one's teeth.
BACKGROUND
Orthodontic braces are designed to align and straighten teeth and position the teeth in regard to a person's bite as a result of force and pressure on the teeth. The primary components needed to help move the teeth, in the case of traditional metal or wire braces, are brackets, bonding material, an arch wire, and ligature elastic, otherwise known as an “O-ring.” Over a period of time, the teeth move when the arch wire exerts pressure on the brackets and teeth. At times, additional force may be applied in specific directions by using springs or rubber bands. Although braces are an effective tool for ultimately aligning and straightening teeth, some patients are hesitant to employ braces due to financial constraints, the known discomfort and unfavorable appearance of braces, and undergoing the braces process typically taking approximately two and a half years before the braces are removed.
Efforts have been made to minimize the discomfort and unfavorable appearance. Outside the pressure that braces place on a patient's teeth, discomfort is primarily caused by the brackets and the end of the arch wire, each typically causing irritation to the lips, cheeks, gums, and/or tongue and sometimes causing mucosal ulceration. However, the efforts proposed to overcome the discomfort of braces or unfavorable appearance require bracket appliances only employable over specialized brackets, an orthodontist to properly position the appliance over the bracket or arch wire, and appliances that interfere with the arch wire. These issues result in inefficiencies to the patient and are costly.
In addition, due to various factors, such as poor teeth maintenance, limited dentistry and/or orthodontic work, many individuals face issues of tooth loss or the like. Tooth loss is highly conspicuous and unsightly and, due to financial constraints, often times cannot be fixed or addressed appropriately. These individuals may want a temporary resolve that will minimize the unsightly and conspicuous nature of tooth loss.
Therefore, it would be advantageous to develop an orthodontic appliance that can be positioned by oneself over a bracket or arch wire that also minimizes patient discomfort and minimizes the unfavorable appearance of braces. It would also be advantageous for the orthodontic appliance to be adaptable to most any sized bracket while not interfering with the arch wire. In addition, it would be advantageous to provide a device and method that will minimize issues of tooth loss or unsightly teeth.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, a simplified view of a bracket system 10 or braces system is depicted over a single tooth 5 and a cap 20 in an unattached position. The bracket system 10 may include a bracket 12 coupled and aligned on the teeth with an arch wire 14 or main wire configured to extend through each of the brackets with a ligature wire 16 coupling the arch wire 14 to the bracket 12. The cap 20 may be sized and configured to be captured by the bracket 12 so as to be positioned over the bracket 12, as depicted in FIGS. 1A and 4. Such cap 20 provides a smooth and rounded surface that is non-abrasive to a patient's mouth, such as their lips, cheeks, gums, and tongue. The cap 20 may be formed with one of various shades of white. In another embodiment, the cap 20 may be somewhat transparent.
With respect to FIGS. 1-3, the cap 20, according to one embodiment, may include a rounded body 22 with a mound-like outer shape. The body 22 may include a wall 24 with an outer surface 26 and an inner surface 28 and a bottom edge 30 extending between the outer and inner surfaces 26, 28. The body 22 may include a first channel 32 and a second channel 34 each extending from the bottom edge 30 and into the wall 24 a predetermined distance. The first and second channels 32, 34 extend from the bottom edge 30 at opposite sides of the body 22 and are aligned with each other. The first and second channels 32, 34 may be similarly sized and include a fairly consistently sized gap 36 along their respective length. The gap 36 of the first and second channels 32, 34 is sized and configured to receive the arch wire 14 upon the cap 20 being placed over the bracket 12 such that the cap 20 makes minimal or no contact with the arch wire 14 in the process of positioning the cap 20 as well as in the attached position of the cap 20. As such, the gap 36 of the first and second channels 32, 34 may be larger than the diameter of the arch wire 14. Further, the gap 36 may be much larger so as to expand a majority of the side portion or width of the cap 20 as depicted with broken lines 31 in FIGS. 1, 1A, and 2. Such enlarged gap may be useful for purposes of making the cap, employing molding techniques, such as injection molding, or any other suitable molding technique, as known to one of ordinary skill in the art.
Referring back to FIGS. 1-3, the cap 20 also includes multiple tabs 40. The tabs 40 provide a retention mechanism for the cap 20 to be maintained to the bracket 12. Each tab 40 may include a base 42 and a free end 44, the base 42 being coupled to the bottom edge 30 or to the inner surface 28 adjacent the bottom edge 30 of the body 22. The multiple tabs 40 may extend from the bottom edge 30 of the body 22 in an inward manner such that the tabs 40 extend toward oppositely facing tabs 40. Further, in a first, un-attached position, the tabs 40 generally extend to provide a partial bottom surface of the body 22 and further, extend in a common plane or a substantially flat configuration. Further, the tabs 40 may extend from the bottom edge 30 at their base 42 toward their free end 44 to generally define an opening 46, the opening 46 extending to a hollow space 48 defined by the inner surface 28 of the body 22.
In one embodiment, the tabs 40 may each extend from the bottom edge 30 so as to be separate and distinct from each other. The tabs 40 may be discrete relative to each other in that they may include a slit or gap that separates each tab from an adjacent tab. As such, each tab 40 may independently flex, move and/or bend relative to each other. Further, each tab 40 may independently bend and provide a bias toward the first, un-attached position such that each tab 40 is resiliently flexible. It should be noted that there are no tabs 40 between the first and second channels 32, 34 so that potential interference to the arch wire 14 of the bracket system 10 is limited.
In one embodiment, the tabs 40 may include a depth thickness 50 that may be less than a thickness 52 of the wall 24 of the cap 20. The tabs 40 may also include a similar depth thickness 50 than that of the thickness 52 of the wall 24 of the cap 20. In another embodiment, the tabs may extend a tab length 54 so as to minimize a size of the opening 46 such that one free end 44 of a tab 40 is directly adjacent to an oppositely facing free end 44 of a tab 40. In another embodiment, adjacent tabs 40 may contact each other along the respective tab lengths 54 so as to minimize any slit or gap between adjacently extending tabs 40. In still another embodiment, one tab 40 may slightly over-lap an adjacently extending tab 40 along their respective tab lengths 54 such that the tabs 40 may at least partially flex or move dependent upon an adjacent tab 40 moving or flexing.
As depicted in FIGS. 1A and 4, the cap 20 may be captured over the bracket 12 such that the tabs 40 are placed in a second, attached position. In the second position, the resiliently flexible tabs 40 may be of a length so that the free ends 44 of the tabs 40 may engage with a base of the bracket 12 such that the tabs 40 bias against the base of the bracket 12 in a bent or bunched-up manner, as depicted in FIG. 4. In one embodiment, in the second position, the tabs may be biased toward the first position. The independently bendable tabs 40 provide a retention mechanism that can readily adjust to the variation in structure of an individual bracket 12. Also, the tabs 40 provide for an effective retention mechanism for various bracket configurations. In this manner, the tabs 40 may readily engage the base of the bracket 12 and retain and capture the cap 20 to the bracket 12. Further, since the tabs 40 do not extend over the channels or the space aligned between the first and second channels 32, 34, such arrangement facilitates the body 22 to fit over the bracket 12 so that the arch wire 14 extends through the channels without interference to the arch wire 14 by the tabs 40 or the body in the process of positioning the cap 20 over the bracket 12.
The body 22 and tabs 40 may be formed of a polymeric material, such as silicone, polyethylene, polycarbonate, polypropylene, polyvinyl chloride (PVC), or any other suitable polymeric material or combination of materials. Coatings may also be employed in the manufacture of the cap 20 on various portions, such as the outer surface 26. As known in the art of polymeric materials, the cap 20 may be manufactured employing known techniques, such as extrusion, injection molding, blow molding, thermo-flowing, casting, transfer molding, or any other known manufacturing methods of polymeric materials. The cap 20 may be formed as a seamless unitary structure. The cap 20 may also be formed in multiple components and then attached with known methods.
Turning now to FIGS. 5 and 6, in another embodiment, a cap 60 may be sized and configured to capture an end 15 of the arch wire 14. The cap 60 in this embodiment may include a spherical or a mound shaped body 61 with a wall 62 having an outer surface 64 and an inner surface 66, the inner surface 66 defining a hollow space 68 in the body 61. Similar to the previous embodiment, the cap 60 may include multiple tabs 70 extending from an edge 72, the edge 72 defined between the outer and inner surfaces 64, 66. Each tab 70 may include a base 74 and a free end 76. The tabs 70 collectively may provide a spoke-like configuration with slits defined between each tab 70. In one embodiment, the free ends 76 of the tabs each may extend toward an axis 78 of the body 61 such that the free ends 76 of the tabs 70 collectively define an opening 80 that extends to the hollow space 68 of the body 61. The tabs 70 may give way to enlarge the opening 80 upon manually pushing the cap 60 over the end 15 of the arch wire 14. Upon the cap 60 being positioned over the wire end 15, the tabs 70 are configured to bias against an outer surface of the arch wire 14 so as to retain or maintain the cap 60 over the wire end 15. With this arrangement, due to the cap 60 having a rounded outer surface 64, the cap 60 minimizes potential irritation and discomfort that would otherwise be caused by the arch wire 14. Such cap 60 may be formed of any suitable polymeric material, such as those described in the previous embodiment, and be formed employing known manufacturing techniques as previously described and known in the art.
With respect to FIG. 7, another embodiment of a cap 90 provided over a bracket system 10 is described. This embodiment is similar to the first embodiment describing the cap and bracket system 10 discussed herein (FIGS. 1-4), except this embodiment includes a shield portion 92. The shield portion 92 may be integrally formed, attached, or adhered to a front side of the cap 90. The shield portion 92 may be sized and configured to be positioned over an entire face of a single tooth 5 to substantially and aesthetically shield the braces of a patient. Such shield portion 92 includes a face surface 94 and a back surface 96. The face surface 94 may be a large smooth surface to protect the gums, tongue, and mouth from irritation and discomfort. The back surface 96 is sized and configured to abut at least a portion of the face of the tooth 5.
The cap 90 and shield portion 92 may be formed of any suitable polymeric material as previously set forth herein and be formed employing known manufacturing techniques. In addition, the shield portion 90 may be formed of a more rigid polymeric material, such as polyvinyl, or any other suitable material, such as a ceramic, composites, laminates or combinations thereof. The shield portion 90 may be formed separately from the cap portion and then adhered together with an adhesive. The shield portion and the cap may also be formed as a unitary and seamless structure.
With reference now to FIGS. 8 and 9, a shield system 100 for aesthetically altering the appearance of one's teeth is disclosed. This embodiment provides similar structural characteristics of previous embodiments, however, this embodiment does not include a mound shaped cap. Rather, this embodiment includes a shield member 102 sized and configured to fit over a bracket 104. The bracket 104 may have a lower profile than brackets employed for braces. The bracket 104 is a stand-alone or wireless bracket for temporarily adhering to one's teeth. The bracket 104 of this embodiment may be an attachment mechanism for the shield member 102. The bracket 104 may include a base portion 106 and an extension 108. The base portion 106 may be adhesively adhered to a person's tooth 105. The extension 108 may be configured to correspond with an attachment portion of the shield member 102. The extension 108 may include a square or rectangular configuration or any other suitable configuration sized to correspond and attach to the shield member 102. The bracket 104 of this embodiment may be formed of a polymeric material, ceramic material, or a metallic material, or any combination thereof.
The shield member 102 may include a face portion 110 and a rear portion 112 with a pocket 114 or hollow space disposed and defined therebetween. The rear portion 112 may include an opening 116 defined therein in the form of a horizontal slit or the like. The rear portion 112 may also include vertical and/or transverse slits 118, transverse relative to the opening 116, that define tabs 120 extending toward the opening 116 in the rear portion 112. Such tabs 120 may extend around the opening 116 defined in the rear portion 112. The face portion 110 may include a more rigid material than the rear portion 112. In another embodiment, the face portion 110 and rear portion 112 may be made of a common material, but be formed of different thicknesses so that the face portion 110 is thicker than the rear portion 112 so that the face portion 110 is more rigid than the rear portion 112. The tabs 120 may include structural characteristics to facilitate maintaining the shield member 102 to the bracket 104.
As in previous embodiments, the shield member 102 may be formed of a variety of polymeric materials, such as silicone, polyethylene, polycarbonate, polypropylene, polyvinyl chloride (PVC), polyvinyl, or any other suitable polymeric material or combination of materials, such as polyvinyl for the face portion 110 and silicone for the rear portion 112. As set forth, the face portion 110 of the shield member 102 may be formed of a more rigid material, which may include ceramics, such as porcelain, and various composites and laminates that may include polymeric materials. The shield member 102 may be colored in various shades of white so as to shield any undesired deficiencies in one's teeth.
In another embodiment, the bracket 104 and shield member 102 arrangement may be employed for changing the aesthetic appearance of one's teeth with a shield member 102 that is not colored with various shades of white. For example, the shield member 102 may be gold or black in color. Depending on the color of the shield member 102, such bracket and shield member arrangement may be employed for a myriad of other purposes, such as costume, popular culture, etc.
In still another embodiment, the shield member 102 depicted in FIGS. 8 and 9 may also be employed to shield brackets employed for braces. Such shield member 102 may be employed with a bracket system 10 for braces (See FIG. 1). As such, the opening 116 and tab 120 arrangement defined in the rear portion 112 would be employed similar to the cap discussed herein to engage a bracket for braces and the face portion 110 would provide the advantageous features of protecting one's mouth from discomfort as well as aesthetically shielding the braces. The shield member of this embodiment may provide a lower profile than the embodiment depicted in FIG. 7, for example.
With respect to FIG. 10, in another embodiment, a shield system 130 is disclosed for aesthetically shielding a gap 132 in ones teeth. In this example, the shield system 130 provides for aesthetically shielding deficiencies in one's teeth, such as tooth loss or any other displeasing deficiencies. The shield system 130 may include a first bracket 134 and a second bracket 136 that each may be adhered to a first tooth 138 and a second tooth 140, respectively. The first and second brackets 134, 136 may be similar to the bracket 104 described in FIGS. 8 and 9. The shield system 130 also includes a shield member 142 that may include the aesthetic appearance of three teeth, namely, a first shield portion 144, a second shield portion 146, and a third shield portion 148, the first and second shield portions 144, 146 being joined by a first intermediate portion 150 and the second and third shield portions 146, 148 joined by a second intermediate portion 152. The shield member 142 may include a face portion 154 and a rear portion (not shown). The rear portion may include an opening and tab arrangement (not shown), similar to that described with respect to FIGS. 8 and 9, at the rear portion of the first shield portion 144 and the third shield portion 148. As such, the opening and tab arrangement in the rear portion (not shown) of the first and third shield portions 144, 148 may respectively couple to the first bracket 134 and the second bracket 136 in a similar manner as depicted in the embodiment of FIGS. 8 and 9. With this arrangement, the shield member 142 is retained by the first and third shield portions 144, 148 and the second shield portion 146 aesthetically shields the gap 132 between the first and second tooth 138, 140. The materials employed in this embodiment may be similar to those described in the previous embodiment.
FIGS. 11-14 describe another embodiment for aesthetically shielding a gap 184 or a lost tooth in one's teeth. FIGS. 11-12 depict one embodiment of a shield member 160. The shield member 160 may include a front side 162 and a rear side 164 with an edge extending between the front side 162 and rear side 164 that defines a periphery 166 of the shield member. The rear side 164 may include an extension portion 168 with, for example, two ends 170 sized and configured to couple to respective first and second coupling members 178, 180 (See FIGS. 13 and 14). As depicted in FIG. 11, the extension portion 168 may extend beyond a width or the periphery 166 of the front side 162. Such extension portion 168 may be snipped or cut down to a desired length to match the width for a given gap between teeth. For example, FIG. 12 depicts the extension portion 168 with a longitudinal length (with the ends being snipped) so as to match the approximate width or periphery of the shield member 160. Further, the periphery 166 of the shield member 160 may be cut or filed back to an appropriate size to match the gap 184 (FIG. 14) between one's teeth. Further, the rear side 164 of the shield member 160 may include a backing 172 for additional reinforcement to the shield member 160.
As depicted in FIGS. 13 and 14, the shield member 160 is coupled between a first tooth 174 and a second tooth 176 by coupling the extension portion 168 to a first coupling member 178 and a second coupling member 180. The first and second coupling members 178, 180 may be respectively adhered to an inside surface of the two teeth adjacent to the gap 184. The first and second coupling members 178, 180 each include a coupling configuration that corresponds with a respective end 170 of the extension portion 168. For example, as depicted in FIG. 13, the coupling configuration is a recess 182 formed in the first coupling member 178 that is sized and configured to receive one end 170 of the extension portion 168. The extension portion 168 may be formed of a resilient polymeric material that can properly retain the shield member 160, but can also be readily removed when desired. The front side 162 or front portion of the shield member 160 may be formed of a thin polymeric material. The front side 162 of the shield member 160 may include one of a variety of shades of white that can be matched to one's teeth. With this arrangement, the shield member 160 and first and second coupling members 178, 180 facilitate one to aesthetically shield the gap 184 in one's teeth.
The first and second coupling members 178, 180 may be formed of a polymeric material, ceramic, or metal, or combinations thereof or any other suitable material as known in the art. The shield member 160 may be formed of one or more materials. For example, the front side 162 and/or the rear side 164 of the shield member 160 may be formed of a polymeric material, similar to those previously set forth, such as polyvinyl, composites, ceramics, laminates or combinations thereof as known by one skilled in the art. Further, the extension portion 168 and backing 172 may be formed of a polymeric material as previously set forth and, preferably, a more compliant polymeric material, such as silicon rubber or the like.
Now with reference to FIGS. 15 through 17, another embodiment of a shield member 202 for purposes of aesthetically shielding one's tooth 205 is provided. Such a shield member 202 may be employed for purposes of shielding the discoloration of one's tooth 205, in which case the shield member may be white or a white-like color to match the other teeth in one's mouth. In another embodiment, the shield member 202 may include a black color or any other color to be employed for, for example, costume purposes.
The shield member includes a body portion 203 having a face surface 204 and a rear surface 206 each defined by a periphery 208. The shield member 202 may include multiple suction cups 210 extending from the rear surface 206. In another embodiment, the shield member 202 may include one suction cup extending from the rear surface 206. Preferably, the shield member 202 may include between two and six suction cups 210, but may exceed six suction cups as the suction cups 210 may be much smaller in comparison to that depicted so as to facilitate additional suction cups. The suction cups 210 may each include a base 212 and a cup portion 213, the cup portion extending from the base with a circular configuration. The base may be centrally located relative to the circular configuration. The base 212 may be in the form of an extension, as depicted, or it may include a low-profile. For example, the base 212 having a low-profile may simply be the interconnection between the cup portion 213 and the rear surface 206 of the shield member 202 such that the rear surface 206 defines one or more concave portions or suction cups therein. Further, each cup portion 213 may include a suctioning surface 214 extending from the base having a concave shape to facilitate effective suctioning of each suction cup 210.
To apply the shield member 202 to a tooth 205, the user may first clean and then dry an outer surface or face surface of the tooth 205. The user may then remove the shield member 202 from its packaging and apply moisture to the suctioning surface 214 of each suction cup 210. Such moistening may be employed with the user's tongue or with a damp cloth. Once the suction cups 210 are moistened, the user may position and align the shield member 202 over a tooth 205 and then apply a force, as indicated by arrow 216, to the face surface 204 of the shield member 202 such that the suctioning surface 214 of one or more suction cups 210 is pressed against the face surface 204 of the tooth 205. In this manner, the suction cups 210 of the shield member 202 become suctioned to the tooth 205 to, thereby, hold the shield member 202 to the tooth and conceal the face surface of the tooth 205.
Such shield member 202, along with the suction cups 210, may be monolithically formed in a unitary and integral manner so as to be a single piece member. In another embodiment, the shield member 202 may be formed separately and with a separate material than the suction cups 210 such that the suction cups are added to the shield member employing various fastening techniques, such as, adhesive, wire fasteners, etc. Further, the shield member 202 may be formed of one or more polymeric materials, ceramics, etc., similar to that described herein for alternate embodiments for a shield member. The suction cups 210 may also be formed with similar polymeric materials or any suitable polymeric material as known to one of ordinary skill in the art that will facilitate effective suctioning of the shield member 202 to one's tooth.
In another embodiment, the suction cups 210 and shield member 202 set forth above may be employed as a shield system similar to the shield system 130 depicted in FIG. 10. For example, at the rear portion or side of a shield system, suction cups may be employed to a first and third shield portion to suction to teeth on both sides of a gap or an unsightly tooth such that a second shield portion extends between the first and third shield portions to hide the gap or unsightly tooth. In this manner, the suction cups may replace the need of adhering temporary stand-alone brackets to the teeth, as set forth and described relative to FIG. 10.
Now with reference to FIGS. 18 through 21, another embodiment of a cap member 230 for positioning over multiple in-line brackets is provided. This embodiment is similar to the cap 20 sized for a single bracket depicted in FIGS. 1 through 4, except in this embodiment, the cap member 230 is sized and configured to engage over multiple in-line brackets of a user's upper teeth or lower teeth.
The cap member 230 may include an elongated body 232 extending between a first end and 246 a second end 248 to define a longitudinal length 262 of the cap member 230. The cap member 230 also may include a wall 234 with an exterior surface 236 and an interior surface 238, the interior surface 238 defining a hollowed portion 240 of the cap member 230. The exterior surface may include a rounded portion (or upper portion) extending laterally between a first side 254 and a second side 256 of the elongated body 232.
The cap member 230 may include a first channel 242 and a second channel (not shown) formed and defined in the wall 234 at the respective first end 246 and the second end 248 of the cap member 230. The channels 242 define a space through which an arch wire 14 may extend upon the cap member 230 being positioned and engaged over and with the brackets 12, similar to that shown in FIGS. 1A and 4.
The cap member 230 may also include an underside 250 with multiple tabs 252 extending from the wall 234 toward each other from the first side 254 and the second side 256 of the cap member 230. For example, the tabs 252 extending from the first side 254 may be a first set of tabs 252 and the tabs 252 extending from the second side 256 may be a second set of tabs 252. Further, the first set of tabs 252 may extend substantially parallel relative to each other. Similarly, the second set of tabs 252 may extend parallel relative to each other. Such tabs 252 may be a continuous extension of the wall 234 at the underside 250 of the cap member 230 such that the tabs 252 each may include a base 258 extending to a free end 260. With this arrangement, the first set of tabs 252 may extend toward the second set of tabs 252 such that there is a gap 255 between the free ends 260 of the first set and the second set of tabs 252. Such a gap 255 may provide clearance to readily receive the in-line brackets into the hollow portion 240 while the tabs 252 engage and grab onto the brackets. The cap member 230 and the tabs 252 may include similar features and structural characteristics as that already described relative to the embodiment depicted in FIGS. 1 through 4, including, but not limited to, wall thickness, tab depth thickness, tab length, etc. Further, the cap member 230 may be formed of similar materials employing similar manufacturing techniques as that described for the cap 20 in the earlier described embodiments.
The cap member 230 of this embodiment may readily be positioned over a set of in-line brackets 12 (See FIGS. 1, 4, and 6) along one's upper or lower teeth and pushed over the brackets 12 so that the brackets are disposed within the hollow portion 240 defined by the interior surface 238 of the cap member 230 with the tabs 252 positioned and engaged with an under or side portion of the bracket 12. As such, along the length 262 of the cap member 230, multiple tabs 252 may be engaging the underside portion of different brackets 12 along the upper or lower teeth with multiple tabs 252 positioned between adjacent brackets that are not engaging a particular bracket along with the arch wire 14 also extending through the hollow portion 240 along the length 262 of the cap member 230. As in the previous embodiments, the tabs 252 may be configured to bias against and hold to the brackets with an interference fit such that the tabs 252 and the free ends 260 thereof may bend and grab to hold and bias against the underside portion of the brackets.
In another embodiment, the cap member 230 may include a shield portion (not shown) extending from the outer or exterior surface 236 of the cap member 230. The shield portion may be similar to the single shield portion depicted and described relative to FIG. 7, except this embodiment may extend along a mid-portion of the cap member and may mimic or correspond with four to six teeth.
In another embodiment, as depicted in FIG. 19, the cap member 230 may include a strip 247 impregnated or imbedded into the body 232 of, for example, the polymeric material. The strip 247 may include an anesthetic base and/or a fluoride base that may include a flavor associated therewith. The flavors may include mint, cherry, strawberry, orange or any other suitable favorable flavor. In another embodiment, the strip 247 may include only one of the above-identified flavors associated with the strip 247 without the base substance of an anesthetic and/or fluoride. In another embodiment, the strip 247 may include only the anesthetic and/or fluoride. The strip 247 may be an elongated, structural strip member that may be embedded into the wall of the cap member 230 along the longitudinal length thereof or the strip 247 may be a chemical substance impregnated into the external surface 236. In one embodiment, the strip 247 may substantially extend along an entire length thereof. In another embodiment, the strip may also extend longitudinally along the length, but as multiple strip pieces, as depicted. In still another embodiment, the strip 247 may be in the form of a thin layer that may be, for example, sprayed, spread, or brushed over the external surface of the cap member 230. The strip 247 may be pre-formed with the cap member 230 or the strip may be applied by the user and come as part of a kit, in which the strip may be applied by spraying or applying such strip from a tube. The strip 247 may be configured to include a time-release such that the strip 247 reacts and releases its flavor, anesthetic, and/or fluoride over a pre-defined period of time. Such time-release may be employed with a particular temperature range or with the mouth's saliva or any other suitable means as known to one of ordinary skill in the art. It should be noted that such a strip 247 may be embodied in the cap 20, 90 described in FIGS. 1 and 7, respectively, or in any other of the embodiments described herein, such as the various shield member embodiments.
