A device (10) for improving the breathing of a user includes an upper arch (12) adapted to receive at least some of the user's upper teeth and a lower arch (14) adapted to receive at least some of the user's lower teeth. A hook (104) is coupled to the upper arch (12) and is uncoupled from the lower arch (14) until the device (10) is inserted into the user's mouth. The hook (104) removably engages the lower arch (14) after the device (10) has been inserted into the user's mouth to adjustably position the lower arch (14) forwardly relative to the upper arch (14). At least a portion (102) of an adjustor (100) associated with the upper arch (12) may rotate to adjust the hook (104) forwardly relative to the upper arch (12). |
