Abstract
A triple layer mouthguard apparatus has a U-shaped mouthguard base with an elastomeric frame embedded therein. The frame includes a wave-shaped contact surface. The mouthguard base includes inner and outer side walls defining an upper channel which has a liner disposed therein. The liner is adapted to form around the teeth when softened. The liner engages the teeth of the upper jaw and is made of a material that softens at a temperature lower than the material of the mouthguard base and becomes softer than the material of the mouthguard base when hardened.
