A method for providing a beneficial effect to an oral cavity of a mammal, the method including contacting a plurality of surfaces of the oral cavity with a liquid effective for providing the beneficial effect to the oral cavity and providing reciprocation of the liquid over the plurality of surfaces of the oral cavity under conditions effective to provide the beneficial effect.

Various systems, method, and compositions for treating a tooth are disclosed herein. For example, an apparatus for treating a tooth is disclosed. The apparatus can include a chamber having an access port which places the chamber in fluid communication with a treatment region of the tooth when the chamber is coupled to tooth. A fluid motion generator can be coupled to the chamber. The fluid motion generator can be configured to direct fluid across the access port to generate fluid motion in the chamber. In various embodiments, fluid motion (e.g., vortices, swirl, etc.) can be induced at or near treatment regions of the tooth, such as a root canal or carious region.

Various apparatus and methods for cleaning teeth and gingival pockets are disclosed herein. A fluid platform can include a pressure wave generator configured to propagate pressure waves through a treatment fluid. The pressure waves may be sufficient to remove undesirable dental deposits from a treatment tooth, neighboring gums, and/or spaces between the tooth and gums.

The present disclosure discloses a water flosser comprises a housing, a tooth irrigation portion, a water nozzle portion, a winding mechanism, and a water pipe configured to be bent and wound. The tooth irrigation portion is disposed in the housing and comprises a water inlet and a water outlet. The water nozzle portion is in communication with the water outlet of the tooth irrigation portion.

A stable water flosser includes a body and a head. A nozzle is provided at the head. A liquid and air storage chamber that is communicated to the nozzle is provided inside the head, and a diameter of the liquid and air storage chamber is larger than that of the nozzle. The water flosser has a compact structure and is capable of effectively avoiding the pressure reduction of the air and the liquid.

A portable oral irrigator includes a nozzle, a handle, an outer water container and an inner water container. The nozzle is at an upper end of the portable oral irrigator. The handle is below the nozzle. The outer water container is below the handle. The inner water container is below the outer water container. A sealing ring is at a bottom of the inner water container for sealing the inner water container. An annular silicone sealing member is at a joining portion of the outer water container and the inner water container. A gasket is between the outer water container and the handle. An air passable silicone seal is on the gasket. With provision of the air passable silicone seal, a raised bottom of the air passable silicone seal contracts to close its cross-shaped opening due to water pressure in the outer water container, thereby preventing leakage.

An oral irrigator includes a sprayer, a spray lance, a control switch, a vessel, a water pipe and a water volume stepless adjustment device. The water volume stepless adjustment device includes an adjusting switch, a controller and a signal output device. A signal output by the controller can be continuously adjusted for adjusting the adjusting switch to continuously adjust the magnitude of pressure of a fluid sprayed from the spray lance. When a user uses the oral irrigator, the user can adjust the water pressure according to personal tolerance and preferences until feeling most comfortable, thereby greatly enhancing the cleaning effect and comfort of the oral irrigator in a using process. The oral irrigator can also be connected to an oral observation instrument, so that under direct vision, the water volume is adjusted, the teeth and the oral cavity are cleaned, and the cleaning process can be shot and photographed.
