A dental mouthpiece is provided that may be attached to a high-suction dental adapter for the purpose of assisting the dental staff during dental procedures through chair-side, hands-free suction, and isolation. Such mouthpiece may include a main body portion, a cheek retractor portion, and a suction connector portion. In some embodiments, the main body portion, cheek retractor portion, and suction connector portion (and sub-portions thereof) may be molded in one piece, preferably by injection molding. In an exemplary embodiment, the mouthpiece may be made of a material that is flexible, translucent, conducive to injection molding, high heat-resistant, and autoclavable. Such a material may include silicone. Because the mouthpiece may be made of a high heat-resistant and autoclavable material, such a mouthpiece may be reusable.

Systems and methods for cleaning teeth by removal of dental biofilm. In one illustrative embodiment, a custom fit tray that fits over the teeth and seals against the gum of a mammal. A number of ports are embedded in the tray, each in fluid communication with a hose or line supplied with either a vacuum or an irrigant/fluid source. A small space between the tray and the teeth provides for fluid to flow around the teeth. A router may be connected to both an irrigant fluid supply reservoir and a vacuum pump to direct either fluid or vacuum to the various hoses with the routing changing over time for optimum cleaning. Air may be injected into the cleaning fluid in varying amounts, to create bubbles, water droplets, and/or boluses of the cleaning fluid to increase and focus the hydrodynamic forces of the fluid upon reaching the teeth.

A dental cleaning appliance includes a fluid delivery system for delivering a burst of working fluid to the teeth of a user; and a control circuit for controlling the delivery of the burst of working fluid to the teeth of a user. The appliance has a first operational mode in which the delivery of the burst of working fluid to the teeth of a user is inhibited and a second operational mode in which the burst of working fluid to the teeth of a user is permitted. During use of the appliance, the control circuit is arranged to effect a transition between the first operational mode and the second operational mode automatically depending on a detected operational parameter of the appliance.

A pacifier for rinsing an infant's or child's mouth and teeth having an aperture extending through its front lip shield and connecting to a port near the front of the pacifier. The port preferably connects the aperture to enclosed channels or tubes preferably contained entirely within the body walls of the pacifier. The enclosed channels or tubes allow fluid communication with beveled openings located on the top side of the pacifier. The beveled openings are preferably forwardly angled to point towards the lip shield and the interior surface of the infant's or child's upper teeth when the pacifier is placed in the infant's or child's mouth so that when water is pushed through the aperture, the water is pushed through the port, the enclosed channels, and out of the beveled openings, and rinses the mouth and teeth.

Embodiments are described wherein a system for brushing the teeth of a person comprises a master input device; a flexible teeth tray configured to at least partially encapsulate one or more of the teeth in a flexible substrate material, the flexible teeth tray comprising one or more vibratory transducers removably coupled to one or more brushing panels; and a controller operatively coupled to the master input device and the one or more vibratory transducers; wherein subject to an input from the master input device, the controller is configured to cause reciprocating brushing motion of the one or more brushing panels against a surface of the one or more encapsulated teeth, to clean the one or more teeth.

A dental treatment system can include a console, a tooth coupler, and an interface member that provides at least one of fluidic, electrical, mechanical, and data communication between the tooth coupler and the console. The tooth coupler (which may comprise a handpiece or a treatment cap) can act as a working end of the system to administer a suitable treatment procedure, such as a cleaning procedure, an obturation procedure, a restoration procedure, etc. The tooth coupler can removably engage the interface member such that the clinician can easily engage and disengage the tooth coupler and interface member.

In some embodiments, a method for removing a foreign object from a root canal of a tooth is disclosed. The method can include positioning a fluid generator to be in fluid communication with the root canal of the tooth. Fluid can be supplied to the root canal. The method can include generating fluid motion and/or pressure waves in the fluid in the root canal with the fluid motion generator. The foreign object can be removed from the root canal with the pressure waves and/or the fluid motion.

An oral irrigator including a fluid reservoir, a pumping assembly, a pressure control assembly, and a nozzle. The pumping assembly comprises a power source, a motor in electrical communication with the power source, and a pump in fluid communication with the reservoir. The pressure control assembly is in fluid communication with the pump; mechanically varies a pressure of a fluid exiting the nozzle to change the outlet pressure of the oral irrigator a high pressure to a low pressure and vice versa.
