Who This May Be Suitable For

Best suited to patients whose square or wide jaw is driven by masseter muscle bulk, particularly noticeable when clenching.

- A square or wide lower face on clenching.
- Teeth grinding or clenching (bruxism).
- A preference for an oval contour without surgery.

Where the shape is mainly bone structure, muscle treatment won’t change it - this is assessed at consultation.

Common Concerns Treated

- A square or heavy-looking jaw
- Jaw tension from clenching or grinding
- A desire for a softer, oval contour

Our Approach:
- Assessment of masseter bulk at rest and on   clenching
- Realistic, staged treatment timeline from the   first consultation
- Dose calibrated to your individual muscle bulk

Doctor-Led Treatment

A course of treatment into the masseter reduces its overactivity, causing it to gradually reduce in bulk as it’s used less forcefully a gradual softening of the jawline over several weeks, not an instant change.

Dose is calibrated to your muscle bulk, typically higher than other areas in this group given the masseter’s size.

A typical course involves two to three sessions spaced 12–16 weeks apart, followed by less frequent maintenance.
