Abstract
A jaw strengthening device may have an upper mouthpiece and a lower mouthpiece. These mouthpieces may be attached to each other by way of a coil compression spring. This allows the upper and lower mouthpieces to shift front and back as well as laterally so that the upper and lower mouthpieces do not track a specific pivot point, but can follow the natural movement of the jaw. A film is wrapped around the spring and expands outwardly as the user bites down on the mouthpieces to push the inside surface of the person's cheek away from the coils of the spring and prevent the coils of the spring from pinching the user's cheek. Additionally, the device may be inserted inside the person's mouth so that the device is not aesthetically obtrusive.
