The Art of Facial Contour

Botox for Masseter Muscle

A dual-purpose treatment for jawline refinement and jaw tension, using Botox to relax the powerful masseter muscle on each side of the face.

What it is

A targeted treatment for a strong or overactive jaw muscle.

Masseter Botox temporarily relaxes the large chewing muscle at the side of the jaw, which may become enlarged from genetics, clenching, grinding, or heavy chewing.

As activity reduces, the muscle can gradually soften in size for a slimmer-looking jawline. Therapeutically, treatment may also reduce clenching force, jaw tension, and TMJ-related discomfort.

Contour and comfort

Your provider assesses bite strength, jaw shape, clenching habits, and facial proportions before choosing dose and placement.

01 Jawline slimming

Can gradually reduce masseter bulk for a softer, more V-shaped contour.

02 Grinding support

May reduce the force of clenching and grinding, especially when stress-related.

03 TMJ comfort

Can help relax jaw muscle tension associated with clenching and discomfort.

Treatment flow

Precise injections into the masseter on each side.

Treatment often takes about 10 minutes. Your provider may ask you to clench so the masseter can be felt and mapped before small injections are placed into the muscle.

01

Assess

Your provider reviews jaw width, clenching pattern, discomfort, and chewing strength.

02

Map

The masseter is identified on each side, often while you gently clench.

03

Treat

Botox is placed into the muscle in small, precise amounts for a balanced effect.

Why patients consider it

A softer jawline with less clenching tension.

Slimmer Jawline

Slimmer Jawline

Reduced muscle activity can gradually refine a bulky or square jaw contour.

Less Grinding Force

Less Grinding Force

Relaxing the masseter may help protect teeth from clenching-related wear.

Tension Relief

Tension Relief

Easing chronic jaw tension may also support fewer tension-related headaches for some clients.

Results

Comfort may come first; contour changes build gradually.

Jaw tension can begin improving as the muscle relaxes, while slimming is usually gradual because it depends on reduced muscle activity over time. Longevity varies by dose, muscle strength, clenching habits, technique, and individual response.
