An oral care implement including a head and a plurality of cleaning elements which may include a first annular cleaning component and a second annular cleaning component. The first annular cleaning component may have a first inner surface defining a first cavity and a first distal end that is sloped from a first low point to a first high point. The second annular cleaning component may a second inner surface defining a second cavity and a second distal end that is sloped from a second low point to a second high point. The first annular cleaning component may located within the second cavity of the second annular cleaning component. The first and second distal ends may be sloped in opposite directions.

A toothbrush includes an elongate handle stem and a brush head which is connected to the handle stem. The brush head carries a bristle array which contains a plurality of bristle bundles which, in order to improve the cleaning effect, in particular in the interdental spaces, have a plurality of bristle bundles attached to an outer edge of the bristle array, which have a diameter of between 0.8 and 1.2 mm and/or are formed from microfilaments with a diameter of 4 to 6 mils, the usage end of which tapers to a tip.

A replacement toothbrush head includes a tubular sleeve having a brush at one end and a drive shaft receptacle at the opposite end. The receptacle extends into the sleeve from a mouth at a tube end to a shoulder spaced from the mouth within the tube. A coupling member is inserted into the receptacle, and a spring clip is positioned between the receptacle and the coupling member, the spring clip having a base positioned between the shoulder and the distal end of the coupling member and a pair of spring arms overlying the sidewall of the coupling member. At least one of the spring arms engages a flexible region of the coupling member such that the flexible region flexes to engage a drive shaft inserted into the coupling member and retain the replacement head on the drive shaft.

The present invention is a full-mouth toothbrush apparatus. The full-mouth toothbrush apparatus comprises a housing, a pair of brush tines, a set of brush connectors, and a set of brush inserts. The set of brush connectors comprises a pair of first brush connectors and a second brush connector. The pair of brush tines is terminally connected adjacent to the housing. The set of brush connectors is distributed about the pair of brush tines. The pair of first brush connectors is terminally distributed along the pair of brush tines. The pair of first brush connectors is hingedly connected along the pair of brush tines. The second brush connector is slidably connected along the pair of brush tines. The second brush connector is positioned between the housing and the first pair of first brush connectors.

The present invention relates to a comprehensive oral care system. The oral care system provides users with an improved dental cleaning system to ensure people can practice optimal oral care routines. The system has an extendable mouthpiece for receiving the teeth and the tongue of a user. The mouthpiece has a plurality of brushes, and more specifically, three brushes for each tooth for brushing. The mouthpiece also releases water, dental rinse agents, and mouthwash for providing complete oral care. The system has a touch panel that can be used for configuration of parameters like speed and pressure of brushes, amount of water, dental rinse agents and mouthwash and other solutions for meeting requirements of individual users. The system uses a digitized dental mold for configuration and generation of the mouthpiece to create a replica of the jaw of users.

The mouth piece toothbrush is a medical device. The mouth piece toothbrush is adapted for use with a patient. The mouth piece toothbrush is a mouthpiece. The mouth piece toothbrush is adapted for use in cleaning the dentition of the patient. The mouth piece toothbrush comprises a dental tray, a plurality of cleaning structures, and a control circuit. The dental tray houses the plurality of cleaning structures and the control circuit. The plurality of cleaning structures clean the dentition of the patient. Each of the plurality of cleaning structures is an electrically powered device. The control circuit controls the operation of the plurality of cleaning structures. The dental tray simultaneously receives the mandibular dental arch and the maxillary dental arch for cleaning.

A method for manufacturing a brush head (10). The method includes molding a tuft carrier (50) having at least one retention element (52) that are positioned relative to a handling plate (101). Excess material (59) may be removed from the tuft carrier. The retention elements are loaded into recesses of the handling plate. A bristle tuft (21) comprised of a plurality of bristles (22) is inserted into the opening (51) of each retention element. A proximal end (23) of each bristle tuft (21) is bonded together with at least a portion of the proximal side (53) of each corresponding retention element (52) to form a merged proximal end head portion (26) that secures the bristle tufts and retention elements together as a plurality of merged tuft assemblies (20). A platen (42) of a neck (40) is positioned in relation to the merged tuft assemblies using a cavity in a base plate. A matrix material (30) is overmolded to at least partially encompass the platen and the merged tuft assemblies and form the brush head.
