Masseter Treatment in BirminghamJaw Slimming and Grinding Relief

The clearest sign is a wide or square jaw that has become more pronounced over time. You may have noticed your face looking wider at the bottom, or a jaw that looks masculine rather than soft. If you grind your teeth at night, you may also have morning headaches, a sore jaw, or worn-down teeth.

Teeth grinding (bruxism) affects many people, often without them realising it. The masseter muscle enlarges from the constant work, which widens the jaw. Masseter treatment relaxes the muscle, which stops the grinding and slims the jaw over the following weeks. A consultation will confirm whether your jaw width is muscle-driven or structural.

Masseter treatment uses the same product as anti-wrinkle treatment, injected into the masseter muscle on each side of the jaw. The injections take a few minutes, and most people describe a sharp scratch that passes within seconds. The muscle begins to relax over the following 7 to 14 days, and the jaw slims gradually over 4 to 8 weeks.

You come back at 14 to 21 days for a free review. If the muscle needs more relaxation, we can add a small amount then. The result lasts 3 to 6 months, after which a maintenance treatment extends the effect. For clients who also want to address lines, see our Anti-Wrinkle Treatments page.

Masseter treatment requires precise placement — the product has to go into the right part of the muscle to slim the jaw without affecting chewing. Hafsa Ashadu-Campbell has over 13 years of NHS clinical experience and treats conservatively. Every treatment includes a free review at 14 to 21 days. We are fully insured and will tell you honestly if your jaw width is structural rather than muscle-driven, because filler or a different approach would be more appropriate in that case.
