A brush head for an electric toothbrush includes a support part supporting upper and lower lateral brush elements and transverse brush elements for the combined brushing of the inner, outer and occlusal surfaces of the upper and lower teeth, and an oscillating device intended to impart an oscillating movement to the support part. The support part is elastically deformable such that it can fit snugly against the upper and lower dental arches during brushing. The oscillating device includes a movable part on which the support part is mounted, and a drive shaft coupled to the movable part in order to move the movable part and the support part in an oscillating manner. The movable part extends between the upper lateral brush elements and the lower lateral brush elements.

This disclosure relates to an oral care appliance and a method for use in oral care for cleaning the teeth of one or two arches using a mouthpiece forming a closed or nearly closed cavity. The mouthpiece is adapted to deform in response to pressure variations inside the cavity and create an action on the teeth. This disclosure includes a description of depression chambers and associated methods that can contribute to the operation of the oral care appliance by affecting the aforementioned pressure variations.

The present invention provides a mouthpiece for a vibratory tooth cleaning device for simultaneously cleaning several, preferably all, of a user's teeth, comprising a holder and a silicone casing substantially completely surrounding the holder. In addition, a vibratory tooth cleaning device and a manufacturing method for a silicone casing and mouthpiece are provided.

The present invention describes a method for a U-shaped teeth brush device having a conformable shape adjusting U-shaped teethbrush module and one or more individual tooth brushes coupled to the power drive mechanism, each brush having a sensor, piezoelectric crystal and transducer and each tooth brush having a block anchor coupled to the power drive, under smart controls, an electronic control system for sensing individual tooth pressure and controlling motor transmission of vibration to prior positioned brushes, whereby a users unique mouth features can be accounted for by adjusting U-shape distal ends to fit through the users mouth and align with users teeth arch for programmatically brushing more than one tooth simultaneously.

This disclosure relates to oral care mouthpieces and methods of forming oral care mouthpieces. A disclosed oral care mouthpiece includes a base shaped to a dental arch. The base elastically deforms in response to pressure variations in the mouthpiece. The mouthpiece also includes a set of one or more supports attached to the base and placed to allow the base to elastically deform in response to the pressure variations in the mouthpiece. The mouthpiece also includes a set of oral care elements attached to the set of one or more supports and placed to transmit pressure to the dental arch when the base elastically deforms in response to the pressure variations in the mouthpiece.

A toothbrush device comprises a cleaner body that defines a cleaning cavity configured for receiving a set of teeth of a user. A powered driving mechanism is coupled to the cleaner body and is configured to impart driven movement to the cleaner body, thereby to effect cleaning of a set of teeth engaged with the cleaning cavity. The cleaner body can be uniquely customized for a specific user, the cleaning cavity being substantially complementary in shape only to the corresponding set of teeth of the specific user. Cleaning elements can be arranged non-uniformly in the cleaning cavity to define focus areas corresponding to identified dental problem areas unique to the specific user.

Disclosed is an apparatus for cleaning periodontal pockets configured to be inserted into the periodontal pockets formed at boundaries between teeth and gums so as to clean the periodontal pockets, the apparatus includes a customized frame configured to have a structure which the user puts in a mouth thereof and manufactured to match shapes of teeth and gums of a user, and inserts provided inside the frame and arranged at the boundaries between the teeth and the gums of the user so as to clean the periodontal pockets, and the inserts are formed at different positions for respective teeth of the user so as to correspond to the boundaries of the teeth and the gums, so that the inserts are capable of being inserted into the periodontal pockets despite differences in positions of the periodontal pockets of the respective teeth.

Hands-free devices adapted for rapid brushing, cleaning and treating users' teeth are provided. In some embodiments, such a device comprises brushes for cleaning each of a user's teeth simultaneously. In some embodiments, such a device is generally U-shaped, accepting, cleaning and/or treating all of a user's teeth simultaneously. In some embodiments, a device is adapted to fit an individual user, based on 3-dimensional imaging. Example customized fluid jets within such devices are provided, introducing dentifrices and other treatments into tooth-conforming channels. In some embodiments, specialized handles are set forth, configured for hands-free use. Example methods and modes for such devices' use are also set forth. In some embodiments, compartments and cartridges with a proprietary form factor for delivering dentifrice and other treatments and for disposing of waste without mess are provided. In some embodiments, observational data are gathered, analyzed and serve as the basis for a treatment action plan.

This application relates to oral hygiene and/teeth cleaning devices and associated methods. The devices can be configured to have a shape that allows all or substantially all of a user's teeth to be cleaned at once. In some embodiments, the devices are configured to be useable, for example, without access to water or a bathroom. The devices can be used to freshen up and clean the user's mouth on-the-go. In some embodiments, the devices are disposable.

This application relates to method of manufacturing a pressure chamber of a dental mouthpiece; to a method of manufacturing a dental mouthpiece and pressure chamber; to a mouthpiece manufactured with these methods, provided with these methods; to J-/U-shaped dental mouthpiece; and to systems comprising said mouthpieces. The method of manufacturing a pressure chamber joins a frame part and a flexible wall part by over-moulding. The method of manufacturing a mouthpiece starts with an essentially flat member comprising pressure chambers, and is folded and bended into a J-shaped or U-shaped trough configuration. The J-/U-shaped mouthpiece may comprise a multiple of trough sections and be flexible to ride along a dental arch and has its handle coupling at the anterior end of the mouthpiece.
