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 cosmetic device with an exchangeable application head and a device body is disclosed, wherein the device body contains a motor and drive mechanism, an actuating switch, a power supply, a head recognition element and a control element adapted to control the motor and drive mechanism based on an actuation of the actuation switch and the application head recognized by the head recognition element. It is provided that the head recognition element comprises at least one mechanical switch disposed on a carrier fixed at the device body. Further, a flexible actuation area is disposed in front of the at least one mechanical switch. The exchangeable application head has at least one recognition generating protrusion actuating through the flexible actuation area on one of the at least one mechanical switches when the exchangeable application head is mounted at the device body.

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.

A dental appliance for removing material from the mouth of a user is disclosed. The appliance has a body with a plurality of bores extending through the body. A cleaning element is positioned in each of the bores. The cleaning elements are disposed to extend beyond the body and are moveably positioned in the bores.

An oral device for a baby is disclosed herein. The oral device includes a head portion, the head portion including one of: (i) a plurality of bristles for brushing gums and/or teeth of a baby, or (ii) a plurality of protrusions for stimulating gums and/or emerging teeth of the baby; a stop portion connected to the head portion, the stop portion sized to prevent over-insertion of the oral device into the mouth of the baby; and a handle portion connected to the stop portion, the handle portion configured to be grasped by the baby or another person for holding and/or manipulating the oral device.

Provided is a skin care device including at least one brush brought into contact with skin of a user, a motor configured to rotate or vibrate at least one of the at least one brush, a battery configured to supply power to the moto, a main body provided with the at least one brush disposed on one surface thereof and having an accommodation space configured to accommodate the motor and the battery therein, and a cradle having an accommodation space configured to accommodate the at least one brush and having a charging module configured to supply power to the battery.

A dental appliance for removing material from the mouth of a user is disclosed. The appliance has a body with a plurality of bores extending through the body. A cleaning element is positioned in each of the bores. The cleaning elements are disposed to extend beyond the body and are moveably positioned in the bores.

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 wireless gum numbing device includes an on or off switch, a soft rubber cover, and a base assembly with the soft rubber cover covering an underside of the base assembly. The wireless gum numbing device includes two lateral support assemblies, a finger holding clip and a fingertip retention piece. The two lateral side assemblies rise horizontally from a left side and a right side of the base assembly and hold a user's finger from moving laterally during use of the wireless gum numbing device. A finger of the user touches the finger holding clip. The fingertip retention piece connects the base assembly to the finger holding clip to prevent the fingertip from moving too far in a forward direction.
