The mouthpiece enables teeth of an end user to clinch up and down so as to exercise the muscles associated with the jaw and head of the end user. The mouthpiece comprises an adjustable resistance. The mouthpiece further comprises an exterior surface that includes a superior dental arch cavity that accommodates the superior dentition. The mouthpiece further comprises an interior surface that includes an inferior dental arch cavity that accommodates the inferior dentition. The mouthpiece comprises a posterior surface that includes a shelf that is adapted to interface with a tongue. Optionally, the superior dental arch cavity has a curvature that coincides with the superior dental arch. Further, the inferior dental arch cavity has a curvature that coincides with the inferior dental arch.
