Jaw Botox Treatment For Medical Uses

Botox in the masseter relaxes overgrown (hypertrophic) muscles. The masseter may enlarge due to excessive chewing (gum) as well as bruxism (teeth clenching). Increased muscle may exacerbate TMJ disorder and related headaches.
Botox is traditionally a cosmetic treatment for lines and wrinkles. However, it has a long history of medically therapeutic uses. Botox works well for many signs & symptoms of bruxism & TMJ, such as aches & pains in the jawline due to excessive clenching.

Safe & Effective For Facial Contouring

We start with a consultation examining your muscle size and other signs of masseter hypertrophy. We examine masseter muscles for asymmetry and determine appropriate dose for each side of the face.

The treatment has no downtime; therefore, patients can leave straight after the procedure to regular daily routines. Botox is administered via a small needle that relaxes the muscles over two weeks.

Patients can observe softening of the masseter muscle within a week, with results continuing over the next few months. The treatment duration is just a few minutes.

Jawline Botox Results (Before and After)

Jaw botox works to reduce the volume that makes the lower face appear wide. Muscles can be enlarged due to usage such as excess gum chewing, weight lifting and nighttime clenching.
