An oral hygiene instrument includes a handle for gripping by a user and a dental floss assembly coupled with the handle. The dental floss assembly includes a support frame and a length of dental floss attached to the support frame for flossing between teeth. The support frame is selectively rotatable relative to the handle around an axis of rotation.

Disclosed herein are embodiments for a handle for securing a patient's mouth in place while an oral procedure is performed. A handle includes a handle head extending from a handle body, the handle head comprising exterior border bumpers to the sides. An indented portion lies in between the border bumpers, the indented portion having grooves oriented substantially perpendicular to a length of the border bumpers. The indented region is configured to receive a patient's teeth and lock the patient's mouth open by preventing the teeth from sliding off the surface of the handle head. With the patient's mouth securely open, a caregiver may then use a second tool (e.g., a toothbrush, flosser, tongue cleaner, etc.) for cleaning the patient's mouth or performing any other oral procedure.

A dental floss insertion device for inserting an end of a length of dental floss into an enclosed oral space. The device may include a body and a tip attached to the body and cooperating with the body to define a floss guide path. A first roller may be positioned on a first side of the guide path and a second roller may be positioned on a second side of the guide path. The second roller may be moveable toward and away from the first roller to open and close a nip that receives the length of floss, thereby allowing a user to apply a compressive force on a piece of floss located between the first and second rollers while simultaneously rolling the second roller to advance the end of the length of floss along the guide path, through the distal orifice, and into an enclosed oral space. The body may include a removable carriage member that defines the floss guide path and supports the first and second rollers.

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.

A flossing device 100 is described having a flossing head 130 connected to a handle 110 The flossing head 130 includes a pair of elongated side posts 135 each having a proximal end and a distal end, a cross bar attaching the proximal ends of the side posts 135, an end ribbon 141 stretched between distal ends of the side posts 135 and a panel 139 connected between the side posts 135 but spaced away from the end ribbon 141 creating a gap 137 which collects and removes tartar and food particles which are scraped off of the surface of the user's teeth. The unique design allows the handle to hold the flossing head 130 at the proper angle to insert it between the user's teeth. The panel 139 may be constructed from a plurality of parallel flossing ribbons, flossing string, or a combination of both. The panels 139 may be embossed or die cut to increase abrasion and efficiency.

An anti-tipping oral hygiene instrument exchanging structure includes a handle member attachable to a base member that includes a weight element, a circular curved section formed on the weight element, a base engaging section formed on the weight element, and a plurality of placing sections formed on the base member. The circular curved section is used in combination with the weight element to prevent the handle member from tipping over. The handle member has a handle engaging portion combinable with one hygiene piece. The hygiene piece includes a mutual engaging section mountable to the handle engaging portion in order to achieve an advantage of fast replacement. The hygiene piece includes a first rod, a plurality of holed sections formed on the first rod, and a plurality of detaching sections formed on the holed sections to provide an effect of assisting the operation and use of floss.

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 means 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.

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.

An automatic dental flosser (10,11,37) includes a floss cartridge or attachment (14,15,17,19) detachably connectable to a power driver (12,13). The attachment comprises a plastic bifurcated member (16,82) supporting a dental floss span for flossing teeth. A rotatably supported floss supply spool (58) is connected to the bifurcated member for continuously replacing used floss spans with clean floss spans. A rotatably supported floss take-up spool (50,72) is connected to the bifurcated member for being driven by the driver to wind used floss drawn from the bifurcated member. Means for encapsulating the used floss and for distributing antimicrobial fluid (69) on the used floss are included to inhibit microbial activity. Means are provided to distribute used floss along a take-up spool for high-capacity used floss storage until disposal of the cartridge. In the unlikely event of a floss snag, such as on a dental appliance, a built-in floss cutter (88) can instantly detach the flosser.
