Provided is an interdental cleaning tool that can be smoothly inserted between back teeth. An interdental cleaning tool according to the present invention includes: a cleaning tool body that is made of a synthetic resin, and includes a grip portion that is capable of being gripped with fingers of a user and a shaft portion that extends in one direction from the grip portion; and a cleaning portion configured to clean between teeth, covering a leading end of the shaft portion, and made of an elastomer, wherein (angle b)/(angle a) is 0.82 or more, where the angle a is a rotational angle (degrees) when a torque value A is measured, the torque value A being a maximum torque value (N.Math.cm) when the grip portion is rotated at a rotational speed of 10 rpm about a position located 6 mm away from a leading end of the cleaning portion, and the angle b is a rotational angle (degrees) when a torque value B is measured, the torque value B being a maximum torque value (N.Math.cm) when the grip portion is rotated at a rotational speed of 10 rpm about a position located 10 mm away from the leading end of the cleaning portion.

An oral irrigator having an irrigator tip, the tip including a handle portion, a tip portion, a channel in fluid communication with the tether and arranged within the handle portion and the tip portion, and an actuator located on or within the handle portion, the actuator arranged to at least partially altar a flow of a fluid through the channel. The oral irrigator further includes a housing, the housing having a reservoir in fluid communication with a pump sub-assembly, a sensor arranged to measure a first pressure or first electrical load within the pump sub-assembly, and a control unit arranged to control an operational current provided to the pump sub-assembly where operation of the actuator produces a second pressure or electrical load measured by the sensor and the control unit is arranged to alter the operational current of the motor in response to the change.

In one embodiment, a dental flosser includes a handle and a housing coupled to the handle. The housing includes a chamber for rotatably receiving a spool having first top and bottom surfaces and a side surface and having a supply of floss wound about the side surface, the supply of floss having second top and bottom surfaces. The housing further includes a floss orifice for directing at least a portion of the supply of floss therethrough. The dental flosser also includes an actuator including at least one contact surface configured to frictionally engage at least one of the first top surface, the first bottom surface, the second top surface, or the second bottom surface. The actuator further includes a biasing member for biasing the at least one contact surface relative to the spool.

Disclosed is a method, and a system, for accomplishing the in situ formation of a gel in an interdental space. This is useful for the interdental application of one or more dental care agents, such as antimicrobial agents or other anti-plaque agents. The invention makes use of a two component system comprising a gelable liquid and a liquid gelling agent capable of bringing about gelation of the liquid. The system of the invention is arranged such that first the gelable, typically viscous, liquid can be applied, and then the liquid gelling agent is forced, e.g. jetted, into the applied gelable liquid. The system is designed such as to prevent the gelling agent and the gelable liquid to come into contact with each other before both have been applied. The system is configured to allow the gelable liquid to be applied prior to the gelling agent.

An interdental brush realizing reuse of parts by a simple structure includes a shaft portion including an internal passage which extends in an axial direction and of which distal end and base end are opened; and a brush on which fibers are implanted over an entire area of a core that is longer than extension length of the internal passage. The shaft portion further includes a grip portion of which a state is changed between a gripping state for gripping the brush, which has been inserted into the internal passage from an opening on a base end side and of which a part protrudes from an opening on a distal end side, to restrict the brush from moving in the axial direction, and a releasing state for releasing gripping of the brush to allow the brush to move in the axial direction.

A dental floss type tooth cleaning device that is configured to clean tooth gap in oral cavity is disclosed. The invention is mainly configured to allow the user, who is preparing to use dental floss to clean tooth gap, to quickly wind the dental floss which follows a floss groove and is tightened and fixed. The dental floss can be dismantled quickly and disposed after use, so as to achieve a recyclable effect.

A dental flosser having a handle, a dental floss support mounted to the handle and having first and second projections, each projection defining a tip, a floss dispensing spool mounted to the handle, and a floss collecting spool mounted to the handle. The dental flosser also includes a thumbwheel operable to rotate the collecting spool to cause uptake of floss from the dispensing spool, across the tips of the first and second projections, and onto the collecting spool, and a spool brake member mounted to the handle and operable to fix rotated positions of the dispensing and collecting spools, and to automatically release the dispensing and collecting spools to rotate upon operating the thumbwheel.

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.
