An electric toothbrush is disclosed, having a handle including a drive motor and a head portion removably coupled to the handle. The head portion includes a brush, an exit port fed by an internal irrigation lumen, and a drive shaft operatively connecting the drive motor to the brush. A disposable irrigant reservoir is removably coupled directly to the head portion. The irrigant reservoir is in fluid communication with the internal irrigation lumen of the head portion. The head portion is configured to be replaceable with respect to the handle, and the irrigant reservoir is configured to be replaceable independent of the head portion. In some examples, the irrigant reservoir is a disposable bulb (e.g., a capsule), and is positioned such that the user can hold the handle while also squeezing the reservoir with the same hand. In some examples, the toothbrush head includes a suction mechanism.

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 toothbrush tip includes a brush head, a plurality of bristle tufts extending from the brush head, a water jet nozzle extending from the brush head, and a cover panel arranged on a rear of the toothbrush tip opposite the bristle tufts.

A powered toothbrush and toothbrush head comprise a transmission housing; a substantially disk-shaped bristle carrier; a plurality of first bristle tufts arranged on the bristle carrier along a first virtual circle; and a plurality of second bristle tufts arranged on the bristle carrier along a second virtual circle, the second virtual circle being concentric with and having a smaller diameter than the first virtual circle, wherein each of the plurality of first bristle tufts includes a plurality of bristles of a first type, having a tapered form.

Disclosed is an oral cleaning kit, including an interdental brush, an oral viewer, a container, and a holder. The container includes an upper cover and a base. Oral cleaning appliances such as the interdental brush, the oral viewer, toothpaste and a toothbrush may be disposed in the container. The base includes a fixed clamping ring and a storage tank. The upper cover may be used as a tooth mug and is detachably mounted on the base. The holder may be provided on the container. When the holder is unfolded, a mobile phone may be disposed on the holder, and the cleaning process may be observed through the mobile phone in real time. The oral cleaning kit has the advantages of carrying convenience, simple use and hygiene.

A dental apparatus for tooth stain removal comprising an elongate body formed of a single piece of plastic. The dental apparatus comprising a distal portion of the body having a distal end for contacting a tooth, wherein the distal portion is pointed and angled relative to an axial direction of the body for contacting and removing stains from a tooth. The dental apparatus further comprising a proximal portion of the body configured to attach onto an electric toothbrush drive mechanism such that driving of the electric toothbrush drive mechanism causes the distal portion of the body to vibrate.

An electric toothbrush includes a handle with a motor and a light source located in a proximal end. A brush head is in a distal end of the toothbrush, and a drive shaft conveys kinetic energy from the motor to the brush head. The drive shaft includes a light guide from the light source to the distal end and contains two layers of an optical medium of differing refractive indices to enable TIR within the light guide. The brush has a tuft plate having bristles and is made of a polymer such that the water contact angle of the tuft plate is less than 90 degrees and is at least partially transparent. The handle and the tuft plate have electrical contacts to make a contact sensor and a movement sensor provides movement data. A computing device processes movement and contact data to determine when to activate the light.

The present disclosure provides a brushhead for a power toothbrush, and the power toothbrush. The brushhead configured for an electric toothbrush, the brushhead being detachably installed on a handle of the electric toothbrush, the brushhead comprising: a brushhead element; and an engaging assembly arranged in the brushhead element and connecting the brushhead element with a driving shaft, wherein the engaging assembly comprises a main body, an accommodating cavity is defined in a first end of the main body along a first direction, the accommodating cavity is configured to accommodate the driving shaft, a material of the brushhead element is different from a material of the main body, and the first direction is a direction from an end of the brushhead element connected with the handle toward an end of the brushhead element away from the handle.
