Patent Description:
To facilitate proper oral cavity health, it is important to ensure that there is adequate cleaning of all dental surfaces, including the interproximal space between teeth. Research has shown that improper cleaning of interproximal spaces leads to gum and periodontal disease, and can lead to caries.

Dental practitioners typically recommend that their patients clean between the teeth using various interdental cleaning methods or devices such as floss, an interdental brush, or a water jet, among other methods. Dental floss, for example, is often recommended for individuals with narrow interdental spaces, and interproximal brushes have been recommended for periodontal patients or for patients with open embrasures.

One major issue with cleaning these interproximal spaces is that every person has different anatomy and morphology of the teeth, thereby creating different sizes, shapes, and forms of the interproximal spaces. There are different interproximal spaces even within the mouth of a single person. To address variations in interproximal spacing, many dental practitioners measure the spacing and prescribe interproximal cleaning aids with different sizes for different sites in the patient's mouth. For example, a <NUM> diameter interproximal brush may be utilized for a first site, a <NUM> diameter interproximal brush may be utilized for a second site, and a <NUM> diameter interproximal brush may be utilized for a third site.

These traditional approaches to cleaning interproximal spaces are onerous. Patients often struggle to follow the dental practitioner's instructions properly, and often forget which interproximal brush to use at which location within the mouth. And for patients that are able to follow the dental practitioner's instructions properly, they tend to quit after few days or few weeks as motivation fades away.

Accordingly, there is a continued need in the art for methods and systems for oral care devices that dynamically adjust an oral care routine based on measurements of the user's interproximal space.

<CIT> describes a dental cleaning appliance including a fluid delivery system for delivering a burst of working fluid to the teeth of a user, and a control circuit for controlling the delivery of the burst of working fluid to the teeth of a user.

<CIT> describes an oral cleaning device comprising a body which carries a set of projections. An actuator device is associated with one or more projections in the form of an electroactive polymer structure.

Based on the received information about interproximal spacing, the oral care device automatically adjusts the oral care routine to improve cleaning of each interproximal space. Adjustments to the oral care routine may include, for example, adjusting a spray pattern and/or intensity, among other options.

The present disclosure describes various embodiments of an oral care device configured to automatically and dynamically adjust an oral care routine. More generally, Applicant has recognized and appreciated that it would be beneficial to provide a device that adjusts one or more parameters of an oral care routine for an interproximal space, based on a measurement of that interproximal space. Accordingly, the methods and systems described or otherwise envisioned herein provide an oral care device that utilizes information about interproximal spacing to automatically and dynamically modify an oral care routine, thereby cleaning interproximal spaces comprising a plurality of sizes, shapes, and forms using a single device. According to an embodiment, the oral care device obtains information about an interproximal space using a mechanical and/or digital measurement. According to another embodiment, the oral care device receives measurement information from another source. The oral care device utilizes the obtained or received information to adjust the cleaning session, thereby improving cleaning of interproximal spaces.

The embodiments and implementations disclosed or otherwise envisioned herein can be utilized with any oral care device. Examples of suitable oral care devices include an oral irrigator, a toothbrush, or other oral care device. However, the disclosure is not limited to these enumerated devices, and thus the disclosure and embodiments disclosed herein can encompass any oral care device.

Referring to <FIG>, in one embodiment, is an oral care device <NUM> used to clean the interproximal spaces between teeth. Oral care device <NUM> includes a handle or body portion <NUM> designed to be held in a user's hand, and an oral care implement <NUM>. Oral care implement <NUM> may have a curved portion at the distal end thereof, to assist in convenient positioning of the oral care implement in the mouth by the user. The oral care implement may have a function head <NUM> at the distal end thereof.

Oral care device <NUM> may also include a user interface <NUM> used to turn the device on or off or implement operation, and may provide for communication with the user. Oral care device <NUM> also includes a controller <NUM>, which is part of control system <NUM> shown in <FIG>. Controller <NUM> may be formed of one or multiple modules, and is configured to operate the oral care device <NUM> in response to an input. Controller <NUM> can comprise, for example, a processor <NUM> and a memory <NUM>. According to an embodiment, an operating system may contain code which, when executed by controller <NUM>, controls operation of the hardware components of oral care device <NUM>.

According to an embodiment, oral care device <NUM> can optionally include one or more sensors <NUM>. Sensor <NUM> is shown in <FIG> within body portion <NUM>, but may be located anywhere within the device, including for example within oral care implement <NUM> or function head <NUM>. According to one embodiment, sensor <NUM> can be integral to controller <NUM>. Sensor <NUM> can comprise, for example, an inertial motion sensor such as an accelerometer, gyroscope, or magnetic sensor. According to an embodiment, sensor <NUM> is configured to provide readings of six axes of relative motion (three axes translation and three axes rotation), using for example a <NUM>-axis gyroscope and a <NUM>-axis accelerometer. As another example, sensor <NUM> is configured to provide the readings of nine axes of relative motion using, for example, <NUM>-axis gyroscope, a <NUM>-axis accelerometer, and a <NUM>-axis magnetometer. Other sensors may be utilized either alone or in conjunction with these sensors, including but not limited to a pressure sensor and other types of sensors, such as a capacitive sensor, a camera, a photocell, a clock, a timer, and other types of sensors. Many different types of sensors could be utilized, as described or otherwise envisioned herein. According to an embodiment, sensor <NUM> is configured to generate information indicative of the acceleration and angular orientation of oral care device <NUM>. The sensor may comprise two or more sensors <NUM> that function together as the <NUM>-axis or a <NUM>-axis spatial sensor system.

Referring to <FIG>, in one embodiment, is a schematic representation of a control system <NUM> of oral care device <NUM>. Control system <NUM> comprises controller <NUM> with a processor <NUM> and a memory <NUM>, which can store an operating system as well as sensor data. The system may also comprise a power source. Control system <NUM> can optionally include a user interface <NUM>, as shown in <FIG>, which is configured to transmit or receive information to the user. An optional sensor <NUM> of the system, which may be an inertial motion sensor such as an accelerometer, gyroscope, or magnetic sensor, generates sensor data in response to motion and communicates that data to controller <NUM>.

A connectivity module <NUM> of the device can be configured and/or programmed to receive and/or transmit data from or to a wireless transceiver (not shown). For example, connectivity module <NUM> may transmit sensor data via a Wi-Fi connection over the internet or an intranet to a dental professional, a database, or other location. Alternatively, connectivity module <NUM> may receive and/or transmit sensor or feedback data via a Bluetooth or other wireless connection from or to a local device (e.g., a separate computing device), database, or other transceiver. For example, connectivity module <NUM> allows the user to transmit sensor data to a separate database to be saved for long-term storage, to transmit sensor data for further analysis, to transmit user feedback to a separate user interface, or to share data with a dental professional, among other uses. Connectivity module <NUM> may also be a transceiver that can receive user input information, such as interproximal spacing information. Other communication and control signals described herein can be effectuated by a hard wire (non-wireless) connection, or by a combination of wireless and non-wireless connections.

According to an embodiment, control system <NUM> of oral care device <NUM> can be programmed and/or configured to automatically and dynamically adjust an oral care routine via a sensing and actuation mechanism <NUM>, based on interproximal spacing. For example, as disclosed or otherwise envisioned herein, oral care device <NUM> can modify an output of the function head <NUM> or other component of the oral care device in order to adapt to a specific interproximal space and improve cleaning of that space. According to another embodiment, oral care device <NUM> can modify a physical structure of the oral care implement itself to adapt to a specific interproximal space and improve cleaning of that space. According to yet another embodiment, oral care device <NUM> may adjust an output to adapt to a specific interproximal space, such as providing a larger or smaller amount of cleaning liquid ejected from the oral care device into the interproximal space during a certain timeframe, among other variations in output. For example, the system may increase the volume of liquid delivered by the device for larger interproximal spaces, and reduce the volume of liquid delivered by the device for smaller interproximal spaces. Many other embodiments of a dynamic sensing and actuation mechanism <NUM> are possible.

Sensing and actuation mechanism <NUM> can receive input from a sensor <NUM> of the oral care device <NUM>, which can directly or indirectly measure interproximal space. Sensor <NUM> can be any of the sensors described or otherwise envisioned herein, and can be programmed and/or configured to obtain sensor data regarding one or more of the user's interproximal spaces before, during, and/or after a cleaning session. Controller <NUM> can receive the sensor data from sensor <NUM> in real-time or periodically. For example, sensor <NUM> may send a constant stream of sensor data to controller <NUM> for storage and/or analysis, or may temporarily store and aggregate or process data prior to sending it to controller <NUM>. Once received by controller <NUM>, the sensor data can be processed by processor <NUM> and the processor can direct the adjustment of the oral care routine accordingly.

Alternatively or in conjunction with this process, sensing and actuation mechanism <NUM> can receive input from an external sensor or information source containing information about interproximal space. For example, measurements of interproximal space may be obtained by the user or a dental professional at a previous time, and that information can be provided to the oral care device. The feedback mechanism receives that information and uses it to dynamically adjust the output of the device for one or more measured interproximal locations.

Referring to <FIG>, in one embodiment, is a function head <NUM> configured to determine the size of an interproximal space and dynamically adjust oral care accordingly. The function head is positioned at or near the end of oral care implement <NUM>, which extends outwardly from the body portion <NUM> of oral care device <NUM>.

According to this embodiment, the function head <NUM> comprises a spacer <NUM> which is configured to assist the user with proper positioning of the oral care device relative to the teeth. The spacer can be a rigid material, or it can comprise or include a softer material. For example spacer <NUM> could be a rigid plastic, or it could be a rubberized or other soft plastic or polymer component extending from the function head in the direction of the user's teeth when the oral care device is positioned within the mouth. When spacer <NUM> touches against or rubs against the user's teeth, the sensing or measuring mechanism is more properly aligned with the teeth and able to obtain one or more measurements of the interproximal space. Additionally, spacer <NUM> can provide the optimal space between the function head outlet <NUM> and the teeth in order to provide improved efficacy of the oral care session.

The function head further comprises an automated sensing and actuation mechanism <NUM> composed of a fixed inner part <NUM> and two movable outer parts <NUM> and <NUM> positioned on either side of the fixed inner part, all of which extend outwardly from function head <NUM> in the direction of the user's teeth when the oral care device is positioned within the user's mouth. The automated sensing and actuation mechanism <NUM> can directly or indirectly measure the interproximal space and can automatically respond to that measurement to change a parameter of the oral care device operation, such as increasing velocity or amount of liquid output or the speed of operation, among many other changes. Referring to <FIG>, one or both of outer parts <NUM> and <NUM> are movable along the function head <NUM> and can be biased away from fixed inner part <NUM>, such as with a spring or other bias. In the default position, the outer part <NUM> is biased away from inner part <NUM> and there is a maximum distance between moveable outer part <NUM> and fixed inner part <NUM>. As the tip or end of moveable outer part <NUM> is pushed against the teeth and at least partially into an interproximal space, outer part <NUM> is pushed toward the inner part <NUM> against its bias, and the distance between the inner part <NUM> and outer part <NUM> is decreased. In this way, the automated sensing and actuation mechanism obtains a mechanical measurement of the interproximal space and can automatically and dynamically respond.

According to an embodiment, fixed inner part <NUM> comprises a head portion <NUM>. Accordingly, as outer part <NUM> is pushed by a tooth against its bias, thereby decreasing the distance between the outer part <NUM> and the fixed inner part <NUM>, the area around head portion <NUM> decreases. So, for example, if the oral care device is dispensing fluid, such as the device shown in <FIG>, the cleaning jet or flow narrows for a narrower interproximal space. When the automated sensing and actuation mechanism <NUM> encounters a wider interproximal space, the outer part <NUM> and/or <NUM> is allowed to move with its bias and the area around head portion <NUM> increases and the cleaning jet or flow widens for this wider interproximal space.

According to an embodiment, outer parts <NUM> and/or <NUM> can be electronically controlled by the oral care device rather than mechanically controlled. For example, outer part <NUM> and/or <NUM> can be moved by an actuator located at least partially within oral care implement <NUM> and/or function head <NUM>. The actuator can respond to interproximal space measurements that the device receives or obtains directly, such as with a camera as described or otherwise envisioned herein.

Referring to <FIG> is an embodiment of the function head <NUM> relative to two teeth <NUM> and <NUM>, which form an interproximal space <NUM> between them. Interproximal space <NUM> in this embodiment is a larger space, and therefore outer parts <NUM> and/or <NUM> are biased out from fixed inner part <NUM> and the cleaning jet or flow is wider and/or faster for this wider interproximal space. In an embodiment in which the positioning of outer parts <NUM> and/or <NUM> is controlled by an actuator, the device obtains or receives information about the spacing <NUM> and moves outer parts <NUM> and/or <NUM> to a wider configuration.

In contrast, referring to <FIG> is an embodiment of the function head <NUM> relative to two teeth <NUM> and <NUM>, which form an interproximal space <NUM>. Interproximal space <NUM> in this embodiment is a smaller space than the interproximal space shown in <FIG>, and therefore outer parts <NUM> and/or <NUM> are pushed against their bias and toward fixed inner part <NUM>, and the cleaning jet or flow is narrower and/or slower for this narrower interproximal space. In an embodiment in which the positioning of outer parts <NUM> and/or <NUM> is controlled by an actuator, the device obtains or receives information about the spacing <NUM> and moves outer parts <NUM> and/or <NUM> to a narrower configuration.

In addition to pushing outer parts <NUM> and/or <NUM> against their bias and toward fixed inner part <NUM>, one or more of outer parts <NUM> and <NUM> can move in other planes relative to the fixed inner part. For example, one or more of outer parts <NUM> and <NUM> can be pushed inward toward oral care implement <NUM> due to interaction with a tooth surface, and the cleaning jet or flow will be wider and/or faster for an interproximal space. Similarly, when outer parts <NUM> and/or <NUM> are not interacting with a tooth surface, or are interacting with a smaller interproximal space, the outer parts will be closer toward the fixed inner part <NUM>, thereby reducing the cleaning jet or flow.

One benefit of the embodiment depicted in <FIG> is that a single function head <NUM> is utilized for a variety of interproximal spaces, and can automatically and dynamically respond to those different interproximal spaces without requiring more than one function head. Accordingly, the user can clean all or most interproximal spaces without multiple oral care implements, function heads, or other manual adjustments of the oral care device.

Referring to <FIG>, in one embodiment, is a schematic representation of a function head <NUM> configured to determine the size of an interproximal space and dynamically adjust the oral care routine accordingly. The function head is positioned at or near the end of oral care implement <NUM>, which extends outwardly from the body portion <NUM>. A spacer <NUM> is configured to assist the user with proper positioning of the oral care device relative to the teeth. The automated sensing and actuation mechanism <NUM> is composed of a fixed inner part <NUM> and two movable outer parts <NUM> and <NUM> positioned on the sides of the fixed inner part, all of which extend outwardly from oral care implement <NUM> in the direction of the user's teeth when the device is positioned within the user's mouth. The embodiment depicted in <FIG> further comprises a sensor <NUM> such as an imaging sensor configured to obtain sensor data representative or otherwise informative of the interproximal space. For example, sensor <NUM> may be a camera or other imager positioned and/or configured to obtain image data of the interproximal space. The data may be actual images, or may be other imaging data representative of the interproximal space.

Although sensor <NUM> is depicted as being affixed to head portion of the fixed inner part, the sensor may be positioned anywhere within or the function head <NUM>. For example, referring to <FIG>, sensor <NUM> is entirely or partially embedded or positioned within the function head <NUM>. The function head may comprise an opening or window with sensor <NUM> positioned behind the opening or window to provide protection to the components which are still able to obtain sensor data. Although not shown, sensor <NUM> may be positioned anywhere along the oral care implement where it will be capable of obtaining interproximal measurement information, including but not limited to along or in spacer <NUM>.

Referring to <FIG>, in one embodiment, is a schematic representation of a function head <NUM> configured to dynamically adjust oral care. The function head is positioned at or near the end of oral care implement <NUM>, which extends outwardly from the body portion <NUM> of oral care device <NUM>. A spacer <NUM> is configured to assist the user with proper positioning of the oral care device relative to the teeth. The sensing and actuation mechanism <NUM> is composed of two outer parts <NUM> and <NUM> which are separated by a space which allows water, air, and/or any other component of a cleaning session to exit the function head outlet <NUM>. According to an embodiment, one or both of outer parts <NUM> and <NUM> are moveable to modify the flow of the water, air, and/or other component from the oral care device. Accordingly, the function head may comprise an actuator configured to move one or both of outer parts <NUM> and <NUM> in response to interproximal spacing information.

Referring to <FIG>, in one embodiment, is a schematic representation of a function head <NUM> configured to dynamically adjust oral care. The function head <NUM> comprises an extension <NUM> comprising or defining a pathway through which water, air, and/or any other component of a cleaning session can travel to function head outlet <NUM>. For example, the width of the outlet of pathway <NUM> may be adjustable to provide a wider or narrower outlet. For a device expelling water and/or air from the outlet, the wider outlet will allow more water and/or air to exit the device and impact the interproximal space, which will improve cleaning of wider spaces. A narrower outlet will allow less water and/or air to exit the device and impact the interproximal space, which will improve cleaning of narrower spaces.

Referring to <FIG>, in one embodiment, is a flowchart of a method <NUM> for dynamically adjusting an oral care routine based on interproximal spacing. At step <NUM> of the method, an oral care device <NUM> configured to obtain and/or receive interproximal spacing information is provided. Oral care device <NUM> can be any of the devices or embodiments described or otherwise envisioned herein. According to one embodiment, oral care device <NUM> comprises a handle or body <NUM> and an oral care implement14 with a function head <NUM>. The oral care device also optionally comprises a controller <NUM> comprising or in communication with a processor <NUM> and a memory <NUM>. Function head <NUM> of oral care device <NUM> can also comprise an actuation mechanism <NUM> configured to dynamically adjust oral care based on interproximal spacing, and can further comprise a sensing mechanism configured to obtain or receive information about interproximal spacing.

At step <NUM> of the method, oral care device <NUM> obtains spacing information about one or more interproximal spaces within a user's mouth. According to an embodiment, oral care device <NUM> comprises a measurement mechanism, which may be mechanical, digital, or both, configured to obtain the spacing information. For example the oral care device may comprise a sensing mechanism such as a mechanical mechanism as described in conjunction with <FIG>, among many other mechanisms. According to another example, the oral care device may comprise a sensing mechanism such as a sensor <NUM> configured to obtain images or other sensor data representative of interproximal spacing information, as shown for example in the embodiments described with regard to <FIG>. According to an embodiment, sensor <NUM> is a camera configured to obtain one or more images for one or more interproximal spaces.

According to an embodiment, there are many other mechanisms for measuring interproximal spaces. For example, interproximal spacing can be deduced by detecting the elasticity of the gums between two neighboring teeth, such as through a tension test or a vibrating probe using indentation measurements. Interproximal spacing may also be analyzed by detecting roughness (such as the stick/slip phenomenon), by measuring resistance changes in an oral care device, by looking at the response of tissues to cold or pressure stimulus, through ultrasound imaging, by temperature changes such as whether the temperature of the interproximal tissue is different from the temperature of the teeth, a blood detection sensor to detect interproximal tissues, capacitive contact forces to measure the accumulation of fluid in interproximal tissues, and/or by measuring swelling using impedance measurements, Doppler measurements, or other measurements. These are just a few ways to measure the interproximal spaces in the user's mouth.

At step <NUM> of the method, which may be performed together with, or instead of step <NUM> of the method, oral care device <NUM> receives spacing information about one or more interproximal spaces within a user's mouth. According to an embodiment, the oral care device receives information about spacing information from another device or another external information source. According to an embodiment, the oral care device is in communication with and receives information from a device that scans or images one or more interproximal spaces of the user's mouth, such as a smartphone, smart mirror, wearable object such as smart glasses, or an oral device other than the oral care device <NUM>, or a dental professional. According to an embodiment, multiple images may be obtained and the image information can be stitched together to give greater coverage of the oral cavity, and thus more interproximal locations, than would be possible by using a single image.

According to an embodiment, the device scans or images the one or more interproximal spaces of the user's mouth and stores and/or transmits that information to the oral care device directly, or to a remote server or storage device that the oral care device can later access. For example, the oral care device may periodically communicate with the remote server, and/or storage device to inquire about interproximal spacing information and any other information required for the method or system.

According to an embodiment, the oral care device comprises a separate function head, or other component configured to measure interproximal spaces using a mechanical and/or digital mechanism. The separate function head or other component can obtain measurement information and store and/or transmit to the oral care device, or to a remote server or storage device that the oral care device can later access. The oral care device may store the measurement information directly, which can be accessed later by a function head configured for dynamic adaptation to interproximal spaces. The separate function head, or other component may be color-coded or otherwise modified or identified to provide differentiating information to the user.

According to an embodiment, the oral care device receives interproximal spacing information from a dental professional. Dental professionals measure interproximal gaps during appointments and can recommend different interproximal function head sizes. The dental professional can then provide that information to the user or to the user's system and that information can be utilized during subsequent cleaning sessions. This may be especially useful for orthodontists, as the user's interproximal spaces may change significantly over time due to an orthodontic treatment such as braces. It may be advantageous to have a record of the size of the interproximal space as it changes over time so that the proper tools and cleaning routine are utilized.

At optional step <NUM>, the system analyzes the obtained and/or received interproximal spacing information. For example, according to an embodiment, a sensing mechanism such as a sensor <NUM> which is configured to obtain images or other sensor data representative of interproximal spacing information is in communication with the controller <NUM>. The controller comprises or is in communication with processor <NUM>, which can perform one or more functions of the method. The controller analyzes the obtained and/or received interproximal spacing information to determine an interproximal space, which allows the system to determine, develop or otherwise identify an appropriate response by the oral care device to that interproximal space. For example, as described or otherwise envisioned herein, the oral care device can modify an output based on interproximal space, and the controller can direct the modification of the output based on the analysis of the obtained and/or received interproximal spacing information. As just one example, the controller may be configured, programmed, or otherwise designed to adapt the output to a certain width, velocity, or other parameter when a certain interproximal spacing is identified.

According to an embodiment, the system analyzes the obtained or received information and determines the interproximal distance or spacing by, for example, measuring the distance between the two teeth, which might be recognized as two white objects. The interproximal distance or spacing may also be determined by measuring the width of the gingiva, which might be recognized as a pink or red color. The interproximal distance or spacing may also be determined by measuring the base of a black triangle, or a region of missing gums between teeth.

At step <NUM> of the method, oral care device <NUM> dynamically and automatically adjusts the oral care routine based on the obtained or received interproximal spacing. According to an embodiment, the controller directs the function head of the oral care device to dynamically and automatically adjust the oral care routine based on the analysis of the obtained or received interproximal spacing. For example, as described with regard to <FIG>, the oral care device may comprise a sensing mechanism such as a sensor <NUM> configured to obtain images or other sensor data representative of interproximal spacing information. The controller analyzes that information and provides the analysis or an instruction to the function head <NUM> to adapt the oral care output based on the interproximal space. According to another embodiment, such as that described with regard to <FIG>, oral care device <NUM> comprises a measurement mechanism and automatically and dynamically adapts the oral care output to each interproximal space.

According to another embodiment, function head <NUM> of oral care device <NUM> comprises two components each having a different function/output. The output that may be different is velocity, spray angle or direction, air/liquid mix, and other parameters. During use, the oral care device obtains or otherwise determines interproximal spacing, and can automatically preferably use one or both components depending on the interproximal space. Alternatively, the oral care device may tell the user to actuate a different component of the function head. According to yet another embodiment, the oral care device may comprise multiple function heads each configured to preferably clean interproximal spaces of a certain size or range, and the system may direct the user to utilize specific function heads in specific locations of the mouth.

According to another embodiment, oral care device <NUM> modifies the cleaning routine of a different device. For example, the oral care device determines or obtains interproximal spacing information, and can utilize that information to dynamically adjust its own cleaning routine, and/or it can utilize that information to cause another oral care device to dynamically adjust its cleaning routine. For example, a flossing device may obtain interproximal spacing information and adjust one or more parameters of the flossing, such as spray velocity, amount, or mixture, and can communicate that information to a toothbrush, or application such that the user - or the device itself - will be directed to adapt a subsequent tooth brushing session. Accordingly, the flossing device and the toothbrush, or application are in wired or wireless communication that allows them to communicate information such as interproximal spacing information in one or both directions. This provides an enhanced cleaning protocol for the user without requiring multiple devices configured to obtain interproximal spacing information.

According to an embodiment, oral care device <NUM> dynamically adapts to obtained or received interproximal spacing information by, for example, directing the user to do extra rinses, to use a specific cleaning liquid, to use a specific function head, to use a specific size or shape of an function head, or any of a variety of other responses. The system may direct the user to order specific cleaning products based on obtained or received interproximal spacing information, or may automatically order or request these products directly via communication with a network and shopping function or application. The system may provide suggestions about where and when to buy such products, such as a location feature for local stores.

At optional step <NUM> of the method, the oral care device or system can provide real-time and/or stored feedback data to a user or to a remote system. For example, the system can transmit real-time feedback data to a computer via a wired or wireless network connection. As another example, the system can transmit stored feedback data to a computer via a wired or wireless network connection. In addition to these feedback mechanisms, many other mechanisms are possible. For example, the feedback can combine interproximal spacing information, cleaning time and efficacy, and other information into a display, report, or even a single value, among other types of feedback.

At optional step <NUM> of the method, the generated feedback is communicated to a user, a device, and/or another individual. The feedback can be real-time feedback, or can be feedback regarding one or more historical sessions. According to an embodiment, the feedback is provided to the user via a smartphone, a computer program, a base station, a remote software service, or via other means. According to another embodiment, the feedback is provided directly to a healthcare professional such as a dentist or dental hygienist.
