A brushing tracker configured to be mounted to a toothbrush has a motion sensor and a transceiver that collect and output raw motion data. The raw motion data is received by a relay and forwarded to a cloud-based remote processing system that processes the raw motion data to determine brushing adequacy based on predetermined criteria. The motion sensor and transceiver are disposed in a flexible case. An attachment band enables the brushing tracker to be affixed to a standard toothbrush for use and affixed to a different toothbrush when desired.

Tooth brushing monitoring system is disclosed that includes a toothbrush with sensors and a base station. The sensors record data regarding the quality, quantity and location of brushing and the system can analyze the data to provide feedback on the quality of brushing. This feedback provides motivation for users to increase their brushing habits, leading to a decrease in plaque, tooth decay and gingivitis

Oral hygiene monitoring system is disclosed to track motion and orientation of an oral hygiene device. The control system may process data output from a motion sensor to determine position and orientation of an oral hygiene device with respect to a user's mouth. In some examples, the system may use machine learning techniques to identify position and orientation, brush stroke type, and other specific actions.

The present disclosure is directed to systems and methods for providing adaptive physical feedback to a user of an oral care device. Methods for providing adaptive physical indicators to a user of a hand-held device comprise: determining, by a controller and one or more sensors of the hand-held device, a current orientation or position of the hand-held device; determining, by a controller of the hand-held device, a deviation from a target orientation for the hand-held device or a proximity of the hand-held device to target locations; determining, by a controller of the hand-held device, a desired correction of orientation or position; and providing, using a sensory feedback module of the hand-held device, a physical indicator to a user.

A toothbrush apparatus, a method, and a medical system. The apparatus includes a sensing module configured to detect one or more brushing parameters for determining at least a brushing intensity. One or more processors are communicatively coupled to the sensing module and are configured to determine at least the brushing intensity and output the determined brushing intensity.

An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.

Formulation delivery systems, formulation delivery devices, and formulation cartridges for the same are provided. Formulation delivery systems include a reusable handle, a formulation dispensing assembly, and a controller. The formulation dispensing assembly includes a reciprocating nozzle assembly and a pump. The reciprocating nozzle assembly is fluidically-coupleable to the formulation cartridge or the cleaning cartridge received within the reusable handle. Formulation delivery devices include a reusable handle configured to receive a formulation cartridge therein, and a formulation dispensing assembly disposed in the reusable handle. The formulation dispensing assembly includes fluid conduits, a pump fluidically connected to the fluid conduits, a reciprocating nozzle assembly, and a controller. Formulation cartridges include a reusable cartridge body, a valve frame, and a disposable refill packet reversibly-coupleable to the reusable cartridge body. The disposable refill packet includes a formulation packet and a body portion configured for insertion into the reusable cartridge body.

The various embodiments described herein include methods, devices, and systems for customizing dental care. In one aspect, a personalized dental care device includes a first customized mouthpiece including a top cleaning tray and a bottom cleaning tray, each customized based at least in part on an electronic 3-D dental model of a respective user's mouth. The personalized dental care device includes one or more power mechanisms, configured to couple with the first customized mouthpiece, and to transmit energy to at least one cleaning tray of the first customized mouthpiece. The personalized dental care device is configured to be operated in a plurality of modes. Each respective mode of the plurality of modes is associated with a different method for providing oral care.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a first component comprising a first housing having an inner surface that defines a first cavity and a second component comprising a second housing having an inner surface that defines a second cavity. When the tracking attachment is coupled to the oral care implement, a first portion of the handle is positioned within the first cavity and a second portion of the handle is positioned within the second cavity.

In one embodiment, an oral care system may include a toothbrush comprising a physical property, and a programmable processor configured to receive physical property data indicative of the physical property of the toothbrush. The programmable processor may be further configured to determine, based at least in part upon the received physical property data, a suggested brushing routine for a user and/or an evaluation of a brushing session of a user
