Suggested is a pacifier, comprising a mouthpiece and a shield further including a vibration-generating device.

A removable fluid connection fitting for an oral irrigator is provided. The oral irrigator may include a base unit including an opening formed therein, an oral irrigator handle including a handle inlet, a fitting removably coupled to the base unit and seated within the opening formed in the base unit, and a tube in fluid communication with the fitting and the handle inlet. The fitting may include a fitting inlet and a fitting outlet, the fitting inlet being in fluid communication with the base unit. The tube may be in fluid communication with the fluid outlet. Fluid from the base unit may flow through the fitting inlet, to the fitting outlet, into the tube, and into the handle inlet.

Oral hygiene devices, systems, and methods are disclosed herein. In some embodiments, the device comprises a disposable shaft configured to be releasably coupled to a reusable base. The shaft may include a head configured to engage an oral tissue and oral contents of a patient's oral cavity to dislodge one or more substances disposed on the oral tissue. In some embodiments, the shaft defines one or more lumens configured to transport a substance between the base of the device and the patient's oral cavity. The device can be configured to deliver a therapeutic agent to the patient's oral cavity to prevent and/or inhibit colonization of the oral cavity by pathogens. In particular embodiments, the device is configured to suction a substance out of the oral cavity and into the device to reduce a risk of the substance being aspirated into the patient's airways.

An improved external head apparatus for reducing the tone of the masticatory muscles in patients with bruxism and/or other craniomandibular dysfunctions (CMD) includes two curved spring-tempered wires and two separate connecting elements. The external head apparatus has a plane of symmetry, which passes through the center of the curved spring-tempered wires. The two separate connecting elements are situated on different sides of the plane of symmetry.

An oral cavity washing device includes a nozzle and a pump that supplies a liquid to the nozzle. The nozzle has a nozzle flow passage and a reduced part that is disposed in an intermediate part of the nozzle flow passage and that is smaller in cross-sectional area than a rest of the nozzle flow passage. A first flow passage and a second flow passage that are in parallel to each other are disposed between the nozzle and the pump. The first flow passage has a first valve that causes the first flow passage to be opened only when the pump sucks the liquid. The second flow passage has a second valve that causes the second flow passage to be opened only during discharge performed by the pump.
