A dental water jet is provided. The dental water jet may include a base unit, a reservoir supported by the base unit, a handle supported by the base unit, and a container covering an opening of the reservoir. The container may include a base supported by the reservoir and a lid movable relative to the base. The container may be configured to store one or more tips for use with the handle.

The invention is concerned with a musical teether for infant. It has a body member including one or more regions or projections on which an infant can bite in use for soothing purpose and a musical unit. The body member is configured to receive or otherwise accommodate the musical unit which is removably engageable with the body member. The teether further has means for transmitting vibrational musical signal from the musical unit to the body member for onward transmission to teeth of the infant, then to jaw bones and skull of the infant, and then to ear bones of the infant, such that the infant can, while biting on the teeth, receive vibrational musical signal arisen from direct vibration on the ear bones of the infant.

Provided is a light irradiated toothbrush, in which light sources, irradiating light having mutually different wavelengths, are arranged in alternation at the bottom of waveguide bristles so that light of different wavelengths give rise to constructive interference which strengthens the intensity of the irradiated light, and the height of the light sources are varied on the basis of the wavelength of the light irradiated therefrom so as to effectively transmit light of short wavelengths to the waveguide bristles, and light having mutually different wavelengths are transmitted by means of the waveguide bristles, thereby effectively transmitting the light to the mouth of a user.

A oral irrigator device (10) for cleaning teeth, including a system (14) for producing a stream of liquid/air bursts and a nozzle (16) connected to the system, and through which the stream of liquid/air bursts are directed. The nozzle can include a guidance tip (26) including a base portion (30), a tip portion (28), and an orifice (31) through which the stream of liquid/air bursts exits at a flow output pattern, and a flow output pattern selection mechanism (90, 90′) connected to or positioned within the guidance tip. A flow output pattern selection mechanism can be configured to be selectively actuated and to vary, upon the actuation the flow output pattern between a first flow output pattern to at least a second flow output pattern.

The present disclosure is concerned with an oral hygiene implement having a longitudinal axis, a carrier element mounted for driven movement, a motion transmitter that has a first end for transferring a drive force to the carrier element, which first end is provided at a position being offset from the longitudinal axis, and the motion transmitter has a second end positioned essentially on on the longitudinal axis or is arranged for being positioned essentially on the longitudinal axis during operation, wherein the motion transmitter has a first coupling part comprising the first end, which first coupling part essentially extends along a centre axis arranged at an angle with respect to the longitudinal axis, and a second coupling part comprising the second end, which first coupling part is fixedly connected with a first connecting portion of an elastic pivot element that allows that the first coupling part and the second coupling part can pivot with respect to each other at least in a first pivoting plane spanned by the longitudinal axis and by the centre axis, and wherein the first coupling part is made from a plastics material, including reinforced plastics materials, having a Young's modulus of at least 5000 MPa or from a metal material, and at least the first connecting portion, in particular the whole elastic pivot element, is made from a plastics material having a Young's modulus of not more than 3000 MPa, optionally of not more than 1000 MPa, further optionally of not more than 500 MPa.

An actuation assembly for an oral irrigator includes a bezel secured to or formed as part of a housing of the oral irrigator, an actuator operably connected to the bezel and moveable relative thereto, and an augmentation fluid positioned between the bezel and the actuator. The augmentation fluid modifies a frictional relationship between the bezel and the actuator to provide a predefined resistance force between the actuator and the bezel as the actuator is rotated relative to the bezel.
