An interdental brush comprising an interdental brush bar and a grip, the interdental brush bar having a central shaft and a joint portion, the central shaft surface axially staggering a plurality of first bristle sets and a plurality of second bristle sets, the first bristle set has two first bristles, and the second bristle set has two second bristles, and each of the first bristles is connected with an adjacent second bristles to form a squeegee. The grip connects the joint portion, and the squeegee can increase the contact area with the teeth to enhance the cleaning effect.

A toothbrush having Dental floss includes a main body having a cartridge housing portion formed in an upper portion at one end and a brush portion formed in a lower portion thereof and a floss cartridge, which includes a bridge for cleaning as area between teeth, having a first gear, a second gear and a floss, wherein the floss cartridge is attachable and detachable to and from the cartridge housing portion, wherein a new floss stored in the floss cartridge is fed by the first gear in the floss cartridge, and the used floss is wound by the second gear.

A multiple purpose oral care device is provided. The device comprises a two-ended manual tool with ergonomically shaped handle and attachment components located at least at a first end to accommodate semi-circular snap-on flossers. The device also comprises disposable implements for dental and gum care that attach to the snap-on flossers and comprise optional structures. The disposable implements comprise at least one of brushes and gum stimulators and are situated at ends of the snap-on flossers. A first optional structure combines a snap-on flosser and two parallel inter-proximal brushes, one on each end of the flosser. The first optional structure is directed to orthodontic patients with braces and patients with fixed restorations comprising at least one of crowns and bridges. A second optional structure comprises two gum stimulators, one with each attached on opposite sides of the snap-on flosser, pointing inward to each other and parallel to floss.

A method and apparatus permitting arbitrary, relative motions of a distal end of a toothbrush or flosser with respect to a handle with real-time selectable motions. The toothbrush has a handle and a post, with a mechanism mechanically coupling the handle to the post permitting relative translational movement of the post with respect to the handle.

A system for classifying the usage of a handheld consumer device having a sensor and an analyzer. The sensor determines usage data at successive time instants and provides a temporally successive sequence of usage data during a usage session. The analyzer classifies the usage of the device with respect to at least one set usage classes and assembles a temporally successive sequence of input tuples of usage data relating to a predetermined time period of the usage session, each of the input tuples having at least one element representing the usage data at the respective time instant and for inputting the sequence of input tuples into at least one artificial neural network arranged to output at least one output tuple comprising a number of elements in accordance with the number of usage classes, each element of the output tuple representing a prediction value that the usage of the consumer device at the given time instant relates to a respective usage class.

A dental cleaning tool includes a body portion defining a longitudinal axis of the dental cleaning tool. The body portion extends from a first end to a second end along the longitudinal axis. The body portion includes a floss assembly formed at the first end of the body portion, a toothpick member formed at the second end of the body portion, and a handle portion extending between the floss assembly and the toothpick member. The handle portion includes a receptacle. The tool further includes at least one secondary cleaning tool coupled to the body portion. The at least one secondary cleaning tool is rotatable relative to the body portion for selectively positioning the at least one secondary cleaning tool between a stowed position, within the receptacle, and a deployed position.

A method and apparatus which permits arbitrary, relative motions of a distal end of a toothbrush and/or flosser with respect to a handle. Said motions are selectable by a user in real time by a selection switch. The toothbrush herein includes an elongated body used as a handle, and smaller elongated member serving as the toothbrush post. A mechanism mechanically couples said handle to said toothbrush post member permitting relative translational movement of said toothbrush post with respect to said handle.
