The utility model discloses a U-shaped electric toothbrush. The U-shaped electric toothbrush includes a handle and a U-shaped brush head. The U-shaped brush head includes an inner brush piece and an outer brush piece separated from each other. Bristles are provided on opposite surfaces of the inner brush piece and the outer brush piece. A driving device configured to drive the inner brush piece and the outer brush piece to move in a reciprocating and alternating manner is provided on the handle. The driving device includes a motor, a connecting rod, a connecting sleeve sheathed on the connecting rod, and a gear set. The motor drives, through the gear set, the connecting rod and the connecting sleeve to move in a reciprocating and alternating manner in a radial direction of the connecting rod. The outer brush piece is connected to an upper end of the connecting sleeve and is drivable to move by the connecting sleeve. An upper end of the connecting rod passes through the connecting sleeve and protrudes upward. The inner brush piece is connected to the upper end of the connecting rod and is drivable to move by the connecting rod. According to the utility model, the inner brush piece and the outer brush piece are drivable to move in a reciprocating and alternating manner in upward and downward directions in an oral cavity to clean teeth with the bristles. Therefore, the amplitude of motion of the bristles is increased, cleaning efficiency is improved, and the time spent by a user on tooth brushing is shortened.

A toothbrush product for cleaning an exposed mesial or distal surface of a tooth or tooth prosthesis comprising: an elongate member comprising a forward end and a backward end, wherein the elongate member comprises a handle portion and the elongate member extends in a longitudinal direction from the forward end to the backward end; a brush head, wherein the brush head comprises a plurality of tufts provided at a forward and/or a backward surface of the brush head and at least one support memberfor the brush head disposed at the forward end of the elongate member wherein the at least one support member is shaped to support the brush head at a transverse distance from the elongate member, wherein the at least one support member comprises a proximal portion and a distal portion to provide a void between the forward end and the brush head.

A dental cleaning apparatus (DCA) includes an elongated member having a brush portion and a handle portion. The DCA includes multiple brushes with different respective geometries situated equiangularly about the brush portion. The brushes may include convex, concave and flat geometries with each brush being designated for cleaning a different respective tooth surface type. For each of the convex, concave and flat bushes, the DCA includes a respective tactile feel region exhibiting the same geometry as the brush type to aid the user in orienting the DCA in the mouth for tooth cleaning purposes.

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.

Toothbrush head for an electric toothbrush comprising a brush which comprises a bristled dome joined to an annular carrier, wherein the bristled dome comprises a supporting dome having a convex outer surface, and bristles which extend outwards from the convex outer surface, and wherein the bristled dome is a monolithic structure comprising fused bristles. The brush can be substantially hemi-spherical, and the head can comprise one or two such brushes.

An apparatus for the interdiction of periodontal disease comprising a device the size of a US quarter coin capable of being chewed by a user, and which is configured with finger protrusions having fabricated blade ends capable of removing plaque from the teeth surface and disrupting plaque accumulated in the gingivae pockets of the teeth. The device of the apparatus is additionally configured with re-fillable inserts holding hygienic formulations to limit bacterial growth and flush plaque debris out of the gingivae pockets of the teeth. Some embodiments of the device of the apparatus are wholly digestible. The device of the apparatus is portable and comes in a plurality of embodiments in different shapes, all having the basic functionality of, self-treating periodontal disease.

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.

The present invention relates to a disposable closed-liquid suction toothbrush helping increase the maximum of convenience for user because: whose hands are free due to no gripping or holding while brushing teeth; no need to open mouth while brushing; brush the whole surface of all teeth simultaneously; actively regulate the injection and extraction of the liquid in the oral cavity; and shorten the time of brushing teeth, comprises an arch body (10); brush bristle layers (30) covering the interior surfaces of the arch body; and a liquid storage system (20) located inside the intestine of the arch body. The characteristics of the above components and the methods of integrating these components into a system, which take advantage of the limited amount of clean liquid available in the device in the inconvenient conditions for cleaning teeth outside the bathroom or public restrooms and/or situations or spaces which are not easy to discharge the waste liquid during the process of brushing teeth.

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.

The brush head of the toothbrush has filaments that are pointed at one end and led through clearances in the bristle carrier. These filaments have a length of about 10-20 mm. The tips of the pointed filaments produce a height profile other than that of a plane and the ends of the pointed filaments that are remote from the tips are melted.
