A system and method of determining and notifying a user when to replace a worn dental cleaning head (104), comprises receiving, from a sensor (106), at least one measured value; calculating, using the measured value, a burn metric of the dental cleaning head; modeling, using the burn metric, an estimated lifetime of the dental cleaning head; determining, from the lifetime model, whether the dental cleaning head is in need of replacement; and notifying the user upon determining that the dental cleaning head is in need of replacement.

An applicator device including at least one holding section, at least one working tip, and a neck section connecting the holding section and the working tip, the device also includes a base body formed at least partially from a first plastic component, the base body being at least partially overmolded by at least one second plastic component that is softer than the first plastic component. In the region of the working tip, the at least one second plastic component at least partially coats the base body, and the coating includes outwardly projecting, bristle-type cleaning elements.

A system that includes a styling tool configured to treat or shape a user's hair; and a client device configured to communicate with the styling tool and provide feedback to the user regarding a user's usage of the styling tool based at least in part on measured data captured by the styling tool. The styling tool may be a hairbrush that includes circuitry and/or sensors configured to detect one or more of sound, acceleration, force, rotation, hair humidity, and ambient temperature and humidity.

A system and method for instant tongue sampling and diagnosis includes acquiring a plurality of tongue images from a plurality of digital oral devices, and a current health conditions, building a diagnosis framework for diagnosing a current health condition of a user by: i) analyzing the collected tongue images with a visual recognition engine to determine tongue characteristics of each tongue captured in the tongue images, and ii) correlating the tongue characteristics with the current health condition, identifying tongue characteristics from a received image of the tongue using the visual image recognition engine, applying the diagnosis framework to the tongue characteristics of the tongue to diagnosis the current health condition of the user, and modifying a graphical user interface of the digital oral device to display a custom health report indicative of the current health condition of the user, in response to applying the diagnosis framework.

A cartridge and method to authorize and adjust the operation of an oral care appliance are disclosed. The oral care appliance along with the cartridge may be used for cleaning, whitening, removing plaque, or in other general oral care applications for providing oral care hygiene.

Described herein is an oral care implement comprising: a handle; and a head coupled to the handle, the head comprising a main body and a release component coupled to the main body, the release component comprising: a water-dissolvable matrix comprising a first polymer having a processing temperature greater than or equal to 130 C.; and a release agent comprising at least one of zinc oxide, potassium nitrate, and tetrapotassium pyrophosphate; wherein the release agent is dispersed throughout the water-dissolvable matrix.

Systems and methods for enhancing a user's efficiency while operating an oral hygiene device (10) is provided. In an exemplary embodiment, at least one image is captured using an image capturing component (602), and a region of interest (820) for operating the oral hygiene device is determined based on the at least one captured image. Characteristics corresponding to a motion of the oral hygiene device operated by the user are extracted. An analysis of the extracted characteristics occurs to determine a quality of motion of the oral hygiene device, and feedback is provided to the user to regarding the determined quality of motion of the oral hygiene device.

A method (600) for estimating a location of an oral care cleaning device (10), including the steps of: (i) providing (610) an oral cleaning device comprising a sensor (28), a guidance generator (46), a feedback component (48), and a controller (30); (ii) providing (620) a guided cleaning session to the user comprising a plurality of time intervals separated by a cue to switch from a first location within the mouth to a second location; (iii) generating (630) sensor data from the sensor; (iv) estimating (640), based on the generated sensor data, the location of the oral care device during the plurality of time intervals; (v) generating (650) a model to predict the user's cleaning behavior; and (vi) determining (660) the location of the oral care device based on the estimated location of the oral care device and the model of the user's cleaning behavior.

The various embodiments described herein include methods, devices, and systems for creating customized dental care. In one aspect, a method includes obtaining a dental model of a particular user's teeth and determining, based on the dental model of the particular user's teeth, a configuration for a set of cleaning elements to be included with the toothbrush device. The method further includes forming the toothbrush device for the particular user based on the dental model of the particular user's teeth, whereby the toothbrush device includes: (i) a cleaner body, personalized for the particular user based on the dental model of the particular user's teeth, that defines a cleaning cavity shaped for receiving the particular user's teeth, and (ii) the set of cleaning elements, integrally formed with the cleaner body, that contact and clean the particular user's teeth during application of the toothbrush device, whereby the cleaning elements have the determined configuration.
