A head unit configured to couple to a handle of an electric toothbrush, wherein the handle generates vibrational energy transferred to the head unit, the head unit comprising a proximal end and a distal end; a base adjacent to the proximal end, an exterior wall extending from the proximal end to the distal end, wherein the exterior encases a plurality of hollow chambers, wherein each of the plurality of hollow chambers are separated by a scaffold, wherein the scaffold connects to the exterior wall; and a bulb having an exterior surface configured to transfer the vibrational energy to an object.

A pineal gland vibration unit which may be designed to fit in the roof of the mouth of a user. The system may be designed to vibrate at a frequency which is pleasing to the senses. The system may be wirelessly operated. The system may induce spiritual awareness while meditating with the system installed. The device may further allow a user to meditate and become more aware of oneself during self-healing processes.

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.

A handle of an oral irrigator is provided. The handle may include a handle housing with a first segment and a second segment configured to couple together and define a cavity there between, a first set of interior walls extending from the first segment, and a second set of interior walls extending from the second segment. A wall of the first set of interior walls and a wall of the second set of interior walls may limit movement of an oral irrigator component at least partially disposed in the cavity.

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.

Suggested is a pacifier, comprising a mouthpiece and a shield further including a vibration-generating device.

A water flosser is provided that may include a body, a reservoir, a cap coupled to the body and a tip extending through an opening in the cap. The water flosser may include a latch assembly that selectively retains the tip to the body. In one embodiment, the cap, the tip and the latch assembly are all rotatable as a unit about a defined axis relative to the body. An ejector button may be provided to actuate the latch assembly. In one embodiment, the ejector button extends through an upper surface of the cap. Actuation of the latch assembly may include displacement of the ejector button in a direction that is parallel with a rotational axis of the tip. In some embodiments, the reservoir of a water flosser includes a tapering volumetric section that concentrates a volume of fluid about an inlet of a tube coupled with a pump.

A water flosser is provided that may include a base, a reservoir positioned above the base, a lid, and a handle in fluid communication with the reservoir such as by a hose. The reservoir of the water flosser may include a recess formed in a reservoir wall for receipt of a hose support structure. An input device (e.g., a power button) may be positioned adjacent an upper portion of the water flosser, such as in or adjacent the lid. Actuation of the input device may include application of a force downward toward the base. The water flosser may include a motor having a dual output shaft, with one end of the shaft being associated with a rotary encoder or other sensing device to determine an operational characteristic of the motor. The motor may be driven by a power source such as a rechargeable battery.
