Enlarged masseter muscles are common and may occur naturally or can grow from excessive teeth grinding or clenching (bruxism), which is often related to stress.

​

With overuse from habitual teeth grinding or clenching, the muscle becomes large and overdeveloped, altering the shape of the lower face often in an asymmetrical manner.

People who suffer from bruxism often report daily headaches, TMJ pain, ear and facial pain, worn down teeth and dental problems.

Previously the only available treatment was expensive dental splints and physiotherapy which often didn’t address the pain associated symptoms.
