Systems and methods for enhancing a user's efficiency while operating an oral hygiene device () is provided. In an exemplary embodiment, motion information of an oral hygiene device is received from one or more accelerometers () located within the oral hygiene device. The received motion information is compared to a targeted motion of the oral hygiene device. The user operating the oral hygiene device is then provided with feedback in response to determining that the received motion information is within a predefined range of the targeted motion information.

Systems, methods, and devices for providing feedback to an individual based on brushing performance, and providing guidance for the individual's brushing, are provided herein. In one exemplary embodiment, after an oral hygiene device is orientated, a determination is made as to a segment within the individual's mouth that a brush head of the oral hygiene device is located. Upon this determination being made, a sub-segment within the individual's mouth where the brush head is located is also determined. A brushing performance within the sub-segment is calculated and displayed to the user. A level of compliance for the particular segment is determined based on the brushing performance of the various sub-segments within the particular segment. If the level of compliance exceeds a pre-set compliance level for that segment, the individual is guided to a different segment within their mouth for brushing.

A varnish composition is provided comprising a hydrophilic oral care agent, such as a peroxide material, dispersed in a solution of a film-forming hydrophobic polymer in a non-polar solvent. The solvent is selected so as to be a good solvent for the polymer and to be susceptible to evaporation. The composition can be applied as a single layer varnish, preferably a whitening varnish. E.g., the dispersed hydrophilic peroxide material is an aqueous peroxide solution, such as a hydrogen peroxide solution, whereby the dispersion is an emulsion.
