What Does Masseter Muscle Botox Do?

Medical professionals frequently use masseter muscle botox to treat two types of concerns.

Patients who complain of “grinding my teeth” Bruxism-TMJ. Patients usually opt for this treatment when other solutions do not control the aches, pain, and associated headaches due to grinding their teeth. TMD (temporomandibular disorder) can cause pain in your jaw joint and the muscles controlling jaw movement.

Square Jaw & Teeth Clenching Are Related

You will notice your jawline change over the years, and a square jaw appears. Now, utilizing masseter botox works the masseter muscle out.

If you suffer from teeth grinding (Bruxism), you clench your teeth at night for hours. Bruxism causes the muscle to enlarge over time, leading to a square jaw appearance. 

Grinding can also cause substantial damage to the teeth. Many studies suggest that Botox can stop the grinding that leads to these problems. Botox may also reduce clenching, tension, and headaches.

Botox is injected into the masseter or temporalis muscle to help reduce symptoms of clenching and teeth grinding. Bruxism is linked with TMJ problems.

TMJ Problems

● Injury to your jaw
● An unhealthy posture
● Uneven teeth or an uneven jaw
● Locked Jaws
● Grinding your teeth at night
● Chewing gum regularly
● Clenching your teeth excessively

Surprisingly, receiving masseter botox would induce not only physical benefits but psychological benefits as well.
