An oral care device has a field generator adapted to generate an electric field in a mouth of a user, responsive to an input control signal. The electric field is for imparting a force upon particles forming a biofilm to be removed by the oral care device or upon cleaning agent particles. A cyclic control signal is generated for intermittent generation of an electric field at a first RF frequency. The use of an intermittent generation of an RF electric field means the force applied to particles (in particular polarized particles) by the field is itself cyclic. The cyclic nature of this applied force is found to be more effective in the disintegration of a biofilm to be removed, and hence makes subsequent mechanical removal, e.g. by brushing, easier.

An apparatus for dental irrigation may be provided to project fluid onto the surfaces of, and the interproximal spaces between, a user's teeth and gum-line. The apparatus may comprise two hollow U-shaped manifolds having orifices located on their interior faces used as fluid jets. The manifolds may be connected, at a central point of reflection, by a rotating inlet joint which supplies the fluid flow. When placed in the user's mouth, the apparatus may be designed to receive the top and bottom sets of teeth in each corresponding U-shaped manifold, with orifices configured to provide fluid jets aligned towards the lingual and buccal side of the teeth. The orifices may be staggered to provide staggered fluid flow. A user's teeth may be cleaned with a controlled fluid flow by moving the apparatus in a sweeping motion between each set of rear molars.

An oral care device having a head with cleaning elements and a handle coupled to the head. The handle may include a selectively rotatable ring arranged between the head and a distal end of the handle that is configured to allow a user to select a desired mode of operation of the oral care device. The handle may include a selectively illuminated light that is configured to display at least one color that visually indicates that certain behaviors, patterns, and/or consistent habits have been performed successfully. The handle may include a processor configured to track a duration of a user's brushing session, a light ring on a bottom surface of the handle, and a pressure sensor. Respective portions of the light ring may be selectively illuminated by the processor to visualize progress toward achieving a predetermined brushing routine time and/or to visualize an over-pressure condition sensed by the pressure sensor.

A mechanical toothbrush, including a housing portion extending along a longitudinal axis, a bristle shaft assembly including a shaft portion disposed within the housing and extending along the longitudinal axis, and a head portion disposed outside of the housing and having a plurality of bristles extending perpendicularly to the longitudinal axis around a circumference of the shaft portion, and an electronic controlling mechanism disposed within the housing portion, the electronic controlling mechanism activating the bristle shaft assembly to rotate about the longitudinal axis.

A dental cleaning appliance includes a handle, and a cleaning tool detachably connected to the handle. The cleaning tool includes a nozzle for delivering a burst of working fluid to the teeth of a user, a stem extending between the handle and the nozzle, and a fluid reservoir for storing working fluid. The fluid reservoir is connected to, and extends around, the stem.

The present disclosure provides a brushhead for an power toothbrush detachably attached to a handle of the power toothbrush, the handle including a vibrating drive shaft, the brushhead comprising: a main body defining a receiving cavity which is configured to receive at least a portion of the vibrating driving shaft, the main body including a cavity wall substantially surrounding the receiving cavity and an end connected to the handle, with an opening which is defined in the end of the main body in air communication with the receiving cavity, so that the vibrating driving shaft is capable of being inserted into the receiving cavity through the opening; and an engaging assembly mounted in a side wall of the main body, the engaging assembly comprising an elastic member, which is made by metal material; wherein, a recess is defined in the outer surface of the side wall, the elastic member is deformably received in the recess, the elastic member is elastically deformed by force provided from the vibrating drive shaft when the brushhead is attached to the handle of the power toothbrush.

An oral care system comprising: a. an electrical motor b. a base assembly comprising: i. an elongated base-assembly main body defining an elongate axis; and/or ii. a battery or a battery compartment optionally including electrical contacts for a battery, the battery and/or the battery compartment being electrically wired to the electrical motor; and c. a head assembly is disclosed herein. Methods and kits are also disclosed.

An oral care system includes an oral care implement and motion tracking attachment configured to allow tracking of the implement during an oral care activity such as tooth brushing. The oral care implement may include a handle and head. The tracking attachment is coupled to the implement and comprises colored tracking markers detectable by a programmable visual-based motion tracking unit. The tracking attachment in one configuration may comprise a housing with plural insertable tracking colored wedges. In another configuration, a colored tracking portion colored panels and optional colored neck band may be formed on or attached to the oral care implement. Both the tracking attachment and tracking portion embodiments as applicable facilitate tracking at least one of a position, orientation, movement, and the like of the oral care implement to which it is attached. The tracking attachment may be non-electric in nature without any onboard electronics in some embodiments.

Systems and method for an electric toothbrush and charging dock. The electric toothbrush may include at least one magnetic member and at least one charging coil in a central portion. The charging dock may include at least one magnetic member and at least one transmitting coil. The charging dock may include a proximal portion which may be attached to a distal portion of the charging dock to be rotatable relative to the distal portion. The charging dock may include at least one unit capable of receiving power from a power source. The energy received by the unit from the power source may be transmitted to the transmitting coil. The energy may be transmitted from the transmitting coil to the receiving coil in the electric toothbrush via inductive or resonance charging. The energy may be transferred from the receiving coil to a battery in the electric toothbrush.
