Abstract: A mouth appliance to promote nasal breathing and reduce or eliminate snoring and to help improve breathing during exercise. The mouth appliance includes upper and lower pieces that are hinged in the rear and conformed to fit the mouth and teeth of a wearer. The upper and lower mouth pieces come together to create a seal and promote nasal breathing. The frame of the mouth appliance may be formed from a hard or semi-hard material, and may be form-fitted to the mouth of a wearer to ensure both comfortable and effective use. The upper and lower pieces include a latching mechanism that allows for the mouth to be opened, closed, or semi-opened during wear and use of the appliance, and also allows for talking and drinking without removing the mouth appliance. The mouth piece can be worn at any time and provide protection of the teeth.

Abstract: A mouth appliance to promote nasal breathing and reduce or eliminate snoring and to help improve breathing during exercise. The mouth appliance includes upper and lower pieces that are hinged in the rear and conformed to fit the mouth and teeth of a wearer. The upper and lower mouth pieces will come together to create a seal and promote nasal breathing. The frame of the mouth appliance will be of a hard or semi-hard material such as plastic, silastic, silicone, or acrylic. As such, it can be form fitted to the mouth of a wearer to ensure both comfortable and effective use. The upper and lower pieces will have a latching mechanism that allows for the mouth to be opened, closed, or semi-opened during wear and use of the appliance, and also allows for talking and drinking without removing the mouth appliance. The mouth piece can be worn at any time and provide protection of the teeth.
