The present invention provides a replacement brush head, comprising: a bristle head, a housing, a transmission shaft and a tail cover, the transmission shaft is arranged inside the housing, and the bristle head is arranged in a transmission manner at a top end of the housing through the transmission shaft, and the tail cover is arranged at a tail end of the housing. The replacement brush head and oral hygiene device provided by the present invention converts a linear motion of the transmission shaft device into a rotary motion, effectively controlling the rotation angle and swing frequency of the brush head, realizing the smooth transmission of the brush head, and also reducing the noise caused by the transmission process and has the technical effect of convenient, fast and low-cost assembly.

A distinguishing Tooth apparatus cleaning device with a tooth polisher figure, and a four sided black Technical Circular Brush with feelers, for cleaning teeth. A battery cleaning device provides users a highly enhanced method with toothpaste in brush stubbles area to better polish teeth. Further comprising, a cover for the brush with a light to view the brushing area of the mouth.

A brush device for an ultrasonic scaler. The brush device for an ultrasonic scaler may include a base portion having a first end portion and an opposing second end portion, wherein the first end portion and the second end portion define a longitudinal axis of the base portion; an insert portion formed at and extending from the first end portion of the base portion, wherein the insert portion is configured to be received in an opening in a distal end of the ultrasonic scaler for attaching the brush device thereto; and a cleaning element extending away from the second end portion of the base.

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.

An electric toothbrush includes a handle, a toothbrush head, and a charging base. One end of the handle is configured for outputting ultrasonic vibrations. The toothbrush head is configured for simultaneously wrapping upper and lower rows of teeth of a human body. The toothbrush head is configured to be disposed on the end of the handle and vibrates with the end of the handle to simultaneously clean the upper and lower rows of teeth of the human body. The charging base is disposed at the other end of the handle and charges the handle. And the charging base includes a sterilization unit for sterilizing the handle and the toothbrush head. The electric toothbrush provided by the present application is convenient to operate, and is configured for being charged through a charging base and being sterilized after being used, with complete functions and a wide application range.

A replacement toothbrush head assembly is provided for an electric toothbrush. The replacement toothbrush head assembly is provided in the form of an assembly that includes a head portion and a stem portion, such that the head portion may be selectively and easily attached and detached from the stem portion. The head includes a plurality of bristles extending from a main body having a coupling portion. The stem includes a corresponding locking portion configured to receive the coupling portion, such that the head is releasably coupled to the stem in an assembled condition.

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.

A head for an oral care implement comprises at least one tooth cleaning element of a first type and at least one tooth cleaning element of a second type. The at least one tooth cleaning element of the first type has a length extension along a longitudinal axis being about 1 mm to about 2 mm shorter than the length extension of the at least one tooth cleaning element of the second type along its longitudinal axis. The at least one tooth cleaning element of the first type is a tuft of a first type comprising a plurality of filaments, each filament having a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels, the projections and channels being arranged in an alternating manner. The at least one tuft of the first type has a packing factor within a range from about 40% to about 55%, preferably from about 45% to about 50%.

A denture brush that includes a frame having a plurality of wall pieces disposed at an outer circumferential part of a flat plate-shaped base, and first bristle tufts are arrayed on the wall pieces, and second bristle tufts 6 are arrayed in a center region of the base, and third bristle tufts are arrayed on an outer circumferential side of the second bristle tufts. When the denture brush is not housed in a holder, the wall pieces are positioned radially along the outer circumferential part of the base so as to be horizontal with respect to the base. When the denture brush is housed in the holder, the wall pieces are supported by a wall surface of a denture-brush-housing portion of the holder, and are positioned so as to stand upright with respect to the base.
