Abstract: A wearable mastication muscle relaxer is provided. The wearable mastication muscle relaxer provides headwear with pressure-applying protrusions selectively disposed along its inward-facing surface so that the pressure-applying protrusions align with the temporalis, masseter, medial and lateral pterygoid muscles. The amount of pressure applied by the pressure-applying protrusions is a function of the engagement of adjustable connection points provided by the headwear. Additionally, pressure can be selectively applied on a pressure-point basis through urging each protrusion by way of an associated pressure plate accessible along an outward-facing surface of the headwear.
