What Is The Masseter Muscle?

The masseter muscle is one of the more powerful muscles in the body. Wrapped around the jaw bone, the masseter’s job is to open and close the jaw in speech and eating.

When this muscle enlarges, the shape of your face can change – sometimes quite dramatically. For some women, this sometimes presents a perception of appearing somewhat masculine.

How Can I Reduce the Size of My Masseters?

BOTOX® Cosmetic is successfully used to reduce the ability of the masseter muscle to exert heavy force. This reduced force allows the muscle to return to a normal size and shape.

The treatment is simple, with results lasting 4 to 6 months.

What Causes Jaw Muscle Enlargement?

Normal action on its own doesn’t usually cause this type of muscle enlargement – though if you tend to eat a lot of nuts, chew on hard candy or chew gum often with a lot of force, chewing alone can be the cause. The more frequent causes are teeth grinding and unconscious clenching of the jaw.What enlarges the masseter muscle?

Anxiety and stress are bedfellows for a lot of people and often it’s not until you see the shape of your jaw become more square that you even realize you are clenching or grinding. Your dentist can provide help with teeth grinding and once you are aware of tenseness or clenching in your jaw, you can take steps to reduce the tension or at least redirect it.

One dentist recommends the following mantra before going to sleep – Three times say out loud, “Lips together, teeth apart”.
