A visual tooth cleaning, grinding and polishing instrument includes a host, an oral observation instrument and a cleaning and polishing tool. The host can drive the cleaning and polishing tool and supply a power source and a control system for an illuminating system, an observation system and the oral observation instrument. A picture shot by a camera of the observation system can be transmitted to a display of the observation system in time, so as to achieve the purposes of cleaning the teeth while observing a process of cleaning the dental calculus, dental plaque and pigmentation on the surface of the teeth with the cleaning and polishing tool and the cleaning effect instantly on a mobile phone, thereby effectively cleaning, grinding and polishing the teeth. A flusher or an electric toothbrush head or other interdental cleaning tools may also be mounted on the host or the oral observation instrument.

A multiple purpose oral care device is provided. The device comprises a two-ended manual tool with ergonomically shaped handle and attachment components located at least at a first end to accommodate semi-circular snap-on flossers. The device also comprises disposable implements for dental and gum care that attach to the snap-on flossers and comprise optional structures. The disposable implements comprise at least one of brushes and gum stimulators and are situated at ends of the snap-on flossers. A first optional structure combines a snap-on flosser and two parallel inter-proximal brushes, one on each end of the flosser. The first optional structure is directed to orthodontic patients with braces and patients with fixed restorations comprising at least one of crowns and bridges. A second optional structure comprises two gum stimulators, one with each attached on opposite sides of the snap-on flosser, pointing inward to each other and parallel to floss.

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 apparatus for performing dental hygiene includes a concave support member integrally coupled to an upper end of a handle portion, and a floss attachment coupled to the concave support member between a first end and a second end of the concave support member. A hollow passage extending from a lower end of the handle portion to the second end of the concave support member is provided, which receives a water flosser tip such that water from the water flosser tip traverses and exits from an aperture shaped end of the hollow passage at the second end of the concave support member onto the floss attachment in a direction substantially parallel to the floss attachment for the apparatus to work as a water floss pick.

An oral care refill head (300), the oral care refill head (300) may be detachably coupled to a handle (200). The handle (200) may include a stem (250) that is received within a connection cavity (326) of the oral care refill head (300). The stem (250) and the connection cavity (326) may have specific geometries and structures to ensure an adequate coupling therebetween. An oral care implement (100), the oral care implement (100) have a pressure sensing assembly, excessive pressure applied onto the oral care refill head (300) will cause the motor (140) and a motor chassis (401) to rock. As the motor chassis (401) rocks, a contact element (456) thereon will actuate a pressure actuator element (455). In response, a control unit (150) may initiate generation of a user perceptible signal to inform the user of the excess pressure.

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.

An oral care device is provided that both simultaneously flosses between teeth and scrapes a tooth surface. The oral care device includes flat floss having a rectangular cross section and a piece of material having greater stiffness than the flat floss directly overlaying an outer surface of the flat floss. The piece of material acts as the scraper and is at least partially arcuate in cross section.

A flossing device including a handle and a selectively lockable floss frame carrying a taught floss string is provided. The flossing device locks the floss frame to the handle to position the taught floss lengthwise parallel to the longitudinal axis associated with the handle. A locking assembly effectuates the selective locking engagement of the floss frame to the handle. The locking assembly may be positioned adjacent two arms formed in the handle defining a slot configured to slidably receive the floss frame.

A dental flosser includes a flosser member configured to secure a piece of dental floss. The flosser member includes a shoulder portion comprising a hinge and two arms coupled to the shoulder portion, each arm configured to secure a respective end of the piece of dental floss. The flosser also includes an adjustment body coupled to the flosser member, whereby linear movement of the adjustment body causes the flosser member arms to articulate about the hinge.

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.
