An automated, hands-free dental floss dispenser is provided herein. Particularly, the dispenser includes a housing and an activation sensor, such as an infrared, motion, or other sensor for detecting the presence of a hand or other object within a dental floss dispensing region and for activating the dispenser. The dispenser further includes a feeding assembly disposed at least partially within the housing, and a dispensing assembly for receiving an amount of dental floss from the feeding assembly. Specifically, the feeding assembly includes a removable and/or replaceable cartridge which at least temporarily retains the dental floss. The dispensing assembly includes a spindle and a spindle activation assembly, wherein the dental floss is fed from the feed assembly to the spindle for dispensing.

An oral care device comprises a head portion and a handle portion. The head portion comprises at least one supporting arm and a base. The supporting arm extends from the base. A sensor is exposed from the supporting arm. The handle portion is configured to move relative to the head portion. The handle portion comprises a processor, wherein the processor is configured to receive signals from the sensor and analyze the signals received from the sensor.

The subject invention comprises methods and an apparatus for making a non-electric dental water flosser. It connects a water flosser tip to a household faucet. The water flosser tip is an outlet for pressurized water to floss teeth. The flosser comprises only eight major parts: a water flosser tip (10), a quick connect fitting (20), a flexible plastic tubing (30), a faucet diverter valve (40), a faucet adapter (50), a supplement tubing (60), a water flosser tip rest holder (70), and an U-shaped shim (80).

The uniqueness of this flosser is its simplicity. All of its parts are commercially available in many hardware or online stores, and each part has many vendors. The parts are inexpensive, easy to assemble, easy to fix/replace, and it does not use electricity. For consumers, it costs less to own and to operate. If it breaks, there are multiple vendors for replacement parts.

A method and apparatus permitting arbitrary, relative motions of a distal end of a toothbrush or flosser with respect to a handle with real-time selectable motions. The toothbrush has a handle and a post, with a mechanism mechanically coupling the handle to the post permitting relative translational movement of the post with respect to the handle.

An oral assembly (100) for use within a mouth of a user. The oral assembly (100) includes an oral device (104) and a collection device (224). The oral device (104) is configured to be usable within the mouth of the user to provide oral health care treatment. The collection device (224) is coupled to the oral device (104). The collection device (224) is movable between (i) a collection mode wherein the collection device (224) collects saliva from the mouth of the user, and (ii) an expulsion mode wherein the collection device (224) expels a liquid into the mouth of the user. A collection tube (226) can be coupled to the collection device (224). The collection tube (226) can be configured to receive saliva that is collected by the collection device (224) from the mouth of the user.

A fluid emitting dental pick device for cleaning is having a handle defined by a body having an interior cavity. A pick component engaged to one end of the body bifurcates a pressurized fluid stream into two individual fluid streams projecting in opposing directions to clean both sides of the teeth concurrently. An optional reservoir holding a secondary fluid can also be employed which mixes fluid from the reservoir into the pressurized fluid stream which is delivered to the teeth with the two individual fluid streams.

A dental flossing device comprising a first body circumscribing a void adapted to receive one or more fingers of a user, an outward-facing surface, opposite from the void, having a first segment comprising at least one pair of cleats arranged to define a circumferential groove for receiving and carrying one or more revolutions of the dental floss formed by wrapping the dental floss along the circumferential groove. A second segment of the outward-facing surface includes a fastener comprising a depression, a crown with a base wall and a niche in the base wall, and a pedestal that connects the base wall of the crown to a floor of the depression. The base wall, niche and the pedestal are configured to provide a space located between the floor of the depression and the base wall to receive and secure a free end of the dental floss. The device permits users to easily hold and manipulate the dental floss into position for flossing, eliminating the problems associated with gripping dental floss directly with the hands.

Disclosed is a new method, and a system, for increasing the pH of a composition applied on teeth and/or gums. The composition is gelable under the influence of a pH change. The pH change typically is a pH increase in the event of a direct pH-triggered gelation. The pH change typically is a pH decrease in the event of gelation induced by ions, such as calcium ions, released from a pH-sensitive carrier. The device comprises a dispensing unit for the composition, a distal end of which is adapted to apply said substance onto teeth or gums. The device further comprises an electrode system comprising first and second electrodes, the first electrode being adapted to be held against the composition at a location at or near teeth or gums, and the second electrode being adapted to be held against the composition at a location away from teeth or gums, The electrode system is adapted so as to provide an electrical potential difference of 1.5 to 10 Volt between the electrodes.

A handle for an electrically operated personal-care implement includes a metal tube housing having a metal wall with an opening and an inner surface, the inner surface defining an inner cavity of the housing for accommodating an energy source, and a switch assembly for activating the energy source. The switch assembly, including a hard switch component and a soft switch component, is arranged in the opening and seals the opening from the inner surface of the wall. The hard switch component comprises a frame having a recess and attached to the inner surface of the metal wall thereby surrounding the opening and providing an undercut between the recess and the inner surface. The undercut is open to the opening, and the soft switch component is positioned in the undercut to at least partially cover the opening.

An electrical appliance for personal care includes a handle with a longitudinal axis, and a plug-on part which can be attached to the handle, wherein a vibration unit having an electric motor and an eccentric element is arranged in the handle, wherein a plug-like coupling structure protrudes from the handle, which plug-like coupling structure forms an interface with a substantially mirror-inverted socket-like coupling structure of the plug-on part, wherein the interface has at least two stages with different circumferential geometry, wherein at least one of the stages has a rotation-preventing device between the handle and the plug-on part, and wherein a stop surface of the handle for the plug-on part extends obliquely with respect to the longitudinal axis of the handle.
