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.

Showerhead devices incorporate sensors to control bath fill levels. Showerheads have interchangeable attachments, including bristle attachments. Oral care devices are attachable to standard shower arms. Pump devices allow various lotions and fluids to be used in conjunction with showers. Shower organizing devices provide for ordered storage and access to accessories. Bathtub spouts including sensors and valves to control bathtub filled levels.

A dental handpiece system includes a dental handpiece for operating a dental burr and providing a stream of water to the dental burr for cooling a tooth being acted upon by the dental burr. The dental handpiece further includes a flush water port for providing a flush water stream that is directed away from the dental burr to allow the dentist to flush a work site in a patient's mouth. The dental handpiece can also include an air outlet for providing a stream of air that is also not directed to the dental burr and that can be used to dry other dental instruments as well as work sites in the patient's mouth.

A toothbrush is provided. The toothbrush may include a brush head having a first brush and a second brush. Each of the first brush and second brush may include bristles extending radially from first ends of the first brush and second brush. The first brush and second brush may rotate in opposite directions along rotational axes parallel to a longitudinal axis of the toothbrush to brush away from the gums of a user and assist with implementing a rolling brushing method.

A dental water jet is provided. The dental water jet may include a base unit, a reservoir supported by the base unit, a handle supported by the base unit, and a container covering an opening of the reservoir. The container may include a base supported by the reservoir and a lid movable relative to the base. The container may be configured to store one or more tips for use with the handle.

A self-cleaning suction device has a user's suction end that self-sanitizes externally and internally before and after use, as well as self-sanitizes internally during use. A cover opens to reveal the user's suction end within a containment unit. As the cover opens, the suction end travels from a lower chamber, proceeds through a middle chamber of a sanitizing agent, and is presented for use. After suction is complete, the suction end retracts through an upper chamber with, a scraping feature that removes debris from the outer surface of the mouthpiece, and proceeds down through the middle chamber of a sanitizing agent and a scraping feature that removes debris and the sanitizing agent from the outer surface of the user's suction end. Upon the sealing closure of the cover, the upper and middle chambers are flushed with a sanitizing agent, which is suctioned away along with any collected debris. The user's suction end resides within a lower chamber and can be decontaminated by a UV-C light entering into the lower chamber and/or corresponding chambers. The suction device can also include a liquid-hydration delivery system.

A cordless dental gas/water syringe is provided. The cordless dental gas/water syringe can be freely carried and operated by a dental practitioner within a dental facility. The cordless dental gas/water syringe includes a portable or wearable body. The body includes a water chamber, a water pump, a gas chamber, a gas valve, a water switch, a gas switch, and a conduit system for fluidic connection. The body can also include a controller including a touch panel and/or a button for controlling the gas switch, the water switch, the gas valve, and/or the water pump.
