Described herein are systems and methods for providing personalized oral irrigation. One variation of a system for personalized oral irrigation comprises a fluid reservoir and a customized oral insert in fluid communication with the fluid reservoir. The oral insert comprises an arrangement of fluid openings positioned based on the individual oral or dental structures of a user's teeth to provide a customized fluid flow over the user's teeth. Also described herein are methods for generating an arrangement of fluid openings in a customized oral insert.

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 device includes a dispensing unit for the composition, a distal end of which is adapted to apply the composition onto teeth or gums. The device further includes an electrode system having first and second electrodes, the first electrode adapted to be held against the composition at a location at or near teeth or gums, and the second electrode 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 first and second electrodes.

The present disclosure relates to a water pumping device for a water flosser, which includes a mounting base, a transmission assembly, a connecting member, and a piston. The transmission assembly includes a first transmission member. The connecting member is disposed in the mounting base in a reciprocally movable manner in a first direction. The first transmission member is rotatable about a first rotation axis perpendicular to the first direction, and in mating connection with the connecting member. The first transmission member is eccentrically disposed with respect to the first rotation axis. During a rotation of the first transmission member about the first rotation axis, the first transmission member reciprocates in the first direction, so as to drive the connecting member to reciprocate in the first direction. The reciprocation of the connecting member in the first direction can drive the piston to reciprocate in the first direction.

An oral hygiene assembly for performing oral hygiene includes a handle that is elongated for reaching into a user's mouth. A vibration unit is integrated into the handle and the vibration unit has an output shaft extending outwardly from the handle. The output shaft vibrates when the vibration unit is turned on. A plurality of heads is provided and a respective one of the heads is removably attachable to the output shaft of the vibration unit such that the vibration vibrates the respective head.

Exemplary devices and methods are disclosed that facilitate a modular dental device including cartridges. The modular dental device includes an energy storage module, dispensing unit, motor, controller, button, and tube, configured to dispense a compound at a dispensing port. The modular dental device includes a chamber that may receive cartridges containing different compounds, and may serve different functions including cleaning and whitening. The modular dental device may be reconfigured to perform different functions by combining different dental device sections, or by changing the order that different dental device sections are connected in.

Luminous dental floss of the present application includes dental floss, an illumination system, and a handle. The dental floss is detachably connected to the handle. The illumination system includes a light source system, a circuit system, a switch, and a power supply system. The light source system is connected to the power supply system through the circuit system. The circuit system and the power supply system are mounted in the handle, and the switch is mounted on the handle. Illumination light emitted by the light source system can illuminate an oral cavity, and especially an observation window is designed on the luminous dental floss of the present application. During use, under the illumination of the illumination system, a process of the dental floss entering a gap between teeth can be directly observed, thereby facilitating cleaning and effectively avoiding accidental injury to gingivae.

An infinity brush has a flaccid belt configured to define a lemniscate. A plurality of work-contacting segments protrude from and are carried by the flaccid belt. A mechanical drive rotates the flaccid belt. Various embodiments of the flaccid belt include a single lemniscate, a plurality of lemniscates, and various simulated lemniscates. In one embodiment, the infinity brush bristle includes non-cylindrical brush bristles with a longitudinal shaft having at least one diameter transition, while other bristles comprise beads of various oval, circular, and cylindrical geometries.

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.

Disclosed is a multi-functional visual electric toothbrush, including a main unit, an oral viewer, an interdental cleaning appliance and an electric toothbrush head. The oral viewer is connected to the main unit, the interdental cleaning appliance is connected to the front end of the oral viewer, and the electric toothbrush head is connected to a toothbrush driving mechanism. A circuit system and a control system of the main unit can not only transfer the energy of a power supply to the toothbrush driving mechanism, so as to drive the electric toothbrush head to work for large-area oral cleaning, but also connect a lighting system, an observation system and a switch of the oral viewer to control the oral viewer to work. The interdental cleaning appliance may be used cooperatively with the oral viewer to perform targeted cleaning on difficult-to-clean food debris in an oral cavity.

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.
