Disclosed are finger-wearable oral hygiene devices having a tapered shape with a plurality of extensions extending from the outer surface of the body, with the plurality of extensions extending around at least most of the circumference of the body member, the extensions being longer near the distal end of the device and shorter near the proximal end of the device, or the extensions arranged in a staggered pattern along the length of the tubular body, or having combination of these features. The device allows gums and teeth to be massaged or cleaned more efficiently and thoroughly, and can also provide greater comfort to a subject during an oral hygiene process.

An apparatus for dental irrigation may be provided to project fluid onto the surfaces of, and the interproximal spaces between, a user's teeth and gum-line. The apparatus may comprise two hollow U-shaped manifolds having orifices located on their interior faces used as fluid jets. The manifolds may be connected, at a central point of reflection, by a rotating inlet joint which supplies the fluid flow. When placed in the user's mouth, the apparatus may be designed to receive the top and bottom sets of teeth in each corresponding U-shaped manifold, with orifices configured to provide fluid jets aligned towards the lingual and buccal side of the teeth. The orifices may be staggered to provide staggered fluid flow. A user's teeth may be cleaned with a controlled fluid flow by moving the apparatus in a sweeping motion between each set of rear molars.

A tooth brush device having bristle touch-points composed of a polymer material (e.g., silicone) provides improved biofilm removal from teeth. The tooth brush device comprises a head with an apex, a base opposite the apex, a front surface, and a back surface opposite the front surface. The front surface of the head includes bristle touch-points arranged along rows. The rows are arranged orthogonal to the longitudinal axis of the head extending from the apex of the head to the base of the head. Each of a plurality of the bristle touch-points is a single solid elongate structure extending from the head and is composed of a polymer material. The device further includes a neck coupled to the base of the head and a handle coupled to the head via the neck.

A dental hygiene system can include a dental cleaning tip, the tip can include rounded protrusions configured to optimize teeth cleaning and stimulating gums; a supporting member, wherein the supporting member can include a tip coupling mechanism, wherein the tip coupling mechanism can connect the dental cleaning tip to the supporting member; and an angled handle, wherein the angled handle can be coupled to the supporting member and extend away from the supporting member, wherein the tip coupling mechanism can permit removal of the dental cleaning tip; wherein the dental cleaning tip can include a first flat surface and a second flat surface oriented parallel along a conical axis of the dental cleaning tip to maximize dental hygiene; and wherein the bases of the rounded protrusions can increase from an apex of the dental cleaning tip to a base of the dental cleaning tip.

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.

The invention relates to a toothbrush having a handle and a head part, on which bristle filaments and at least one flexible cleaning element are arranged. According to the invention, the at least one flexible cleaning element is arranged on a carrier element which consists of a hard material and is connected to the head part. The invention also relates to a process for producing such a toothbrush.

An oral care implement having a collapsible elastomeric element. The oral care implement may include a body having a handle portion and a head portion. Furthermore, an elastomeric element may extend from the body. The elastomeric element may comprise a hollow body that has an internal cavity, the hollow body having a base section, a middle section, and a distal section that includes a free distal tip, each of the base, middle, and distal sections coupled together by a pre-weakened section. The elastomeric element may be configured to alternate between a collapsed state and a normal state.

An apparatus may include one or more manifolds, each including a shell having an inner portion and an outer portion. Each shell may have a first set of outlets in a first wall and a second set of outlets in a second wall that approximately faces the first wall. Each manifold is shaped to accommodate a tooth. A rotating inlet joint, having an inlet channel and a rotating joint, may enable fluid flow into each manifold from the inlet channel at any angle relative to an axis of rotation defined by the rotating joint. In each manifold, the first set of outlets and the second set of outlets are oriented towards a tooth and/or gums associated with the tooth. The inner portion and the outer portion of each shell cooperate to direct fluid flow substantially horizontal to, and then substantially perpendicular to, the fluid flow exiting the inlet channel.
