The interchangeable mouth shields disclosed herein include a lip-anterior portion and teeth tray that can be releasably coupled together. The lip-anterior portion includes a panel positioned anterior to a lip shield. The panel can be customized to be different shapes and have decorative features. The interchangeable mouth shield includes a vent enabling a user to breathing through the interchangeable mouth shield during use. The teeth tray can be selectively flavored.

The present invention discloses a mouthguard with light emitting function. The mouthguard with light emitting function includes an occlusion unit which is bitten by teeth between the maxilla and the mandible of a wearer. A front end of the occlusion unit is provided with a protector which includes a holding chamber. The mouthguard also includes a lower cap, which is disposed in the holding chamber of the protector; an electric module, which is disposed in the lower cap and includes a control circuit, light emitting devices and a push button; and an upper cap, which covers the electric module to clip and fix with the lower cap. By pressing the push button, the light emitting devices are activated to emit light, thereby achieving the effect of alerting and highlighting.

A mouthguard according to an embodiment of the present disclosure includes an occlusion portion that is configured to be disposed between and engaged by at least some of the upper teeth and at least some of the lower teeth of a wearer. The mouthguard further includes a protection portion coupled to the occlusion portion. The protection portion is configured to be disposed laterally and anteriorly relative to the upper teeth of the wearer. The protection portion includes an interior surface that is configured to face toward the teeth of the wearer. The protection portion further includes an exterior surface opposite the interior surface and configured to face away from the teeth of the wearer. At least a portion of the exterior surface is a textured surface.

A mouthguard according to an embodiment of the present disclosure includes a pair of spaced lateral bite wings, a conduit defining an air channel extending between forward portions of the lateral bite wings, and a lip shield member and/or a flange disposed around and extending radially outward with respect to a forward end of the conduit. The conduit is tapered inward from its forward end toward its rearward end, and defines an incisor engaging surface proximate the rearward end of the conduit, and a lip engaging surface between the incisor engaging surface and the forward end of the conduit.

A mouthguard according to an embodiment of the present disclosure includes a teeth engagement portion having a medial surface. An anterior surface is coupled to the teeth engagement portion opposite the medial surface. A first breathing channel extends from the anterior surface to the medial surface. A second breathing channel extends from the anterior surface to the medial surface. A third breathing channel extends from the anterior surface to the medial surface. A first interior wall is disposed between the first breathing channel and the second breathing channel. The first interior wall is configured to be aligned with a first upper incisor of a wearer. A second interior wall is disposed between the second breathing channel and the third breathing channel. The second interior wall is configured to be aligned with a second upper incisor of the wearer.

The present invention discloses a mouthguard. The mouthguard includes an occlusion unit to be bitten by teeth between the maxilla and the mandible of a wearer. A front end of the occlusion unit is connected to a protector for protection. The occlusion unit and the protector are transfixed with an exhalation opening, and the protector is provided with a groove unit to emplace a fixing body. The fixing body is provided with a fan which can rotate relatively on the fixing body, so that the wearer can inhale through the nose and exhale through the mouth to breathe, which drives the fan to rotate, thereby increasing the vital capacity.

The present invention relates to a buccal valve, suitable for modifying the respiratory flow of a user, comprising a valve body, adapted to be arranged between the dental arches of the user, wherein said valve body comprises one or more airflow passages therethrough; and one or more valve flaps configured to be connected to the valve body. Advantageously, the valve body and the valve flaps are arranged so that, when the buccal valve is installed in the buccal cavity of the user, the one or more valve flaps are positioned in the buccal cavity proper and exposed to direct contact with the tongue of the user. Also, the valve flaps are adapted to regulate the flow rate and direction of the airflow entering the buccal cavity proper, through the airflow passages, towards the palate, the dental arch, or the sublingual areas of the buccal anatomy depending on the position of the tongue.
