It helps with jaw clenching, teeth grinding (bruxism), tension headaches, jaw discomfort, and a bulky or square-looking jawline.

Masseter treatment involves a direct application of cosmetic fillers into the masseter muscles — the muscles at the sides of your jaw that control chewing. This is a powerful solution for those who suffer from jaw clenching, teeth grinding (bruxism), or wish to soften a square jawline for a slimmer facial profile.
How it works:
The treatment weakens the masseter muscle over a period of 3 months, reducing its size and activity. This not only helps relieve physical discomfort but also contributes to a sober, more contoured facial shape.
Treatment time & results:
Masseter treatment reduces jaw tension, teeth grinding, and the appearance of a square jawline by relaxing the large chewing muscles on either side of your jaw. At Chatham Dental, we take a safe, precise, and medically informed approach to ensure effective and natural-looking results.
Here’s what the treatment includes:
A detailed examination of your jaw muscles, bite habits, and clenching patterns to confirm that masseter treatment is suitable for you.
Your clinician determines the correct amount of product based on muscle size and your goals (jaw slimming, tension relief, or both).
Small, accurate injections placed directly into the masseter muscle to reduce activity over time.
The procedure takes 15–20 minutes with minimal discomfort and no downtime.
A review appointment to assess results and check muscle response, usually 4–6 weeks later.
Clear guidance on what to expect, how to protect results, and how often top-ups may be needed.
Masseter treatment is both functional and aesthetic. Whether you want relief from teeth grinding or a softer jawline, we’ll build a plan that suits your needs and ensures natural, balanced results.

Most patients feel improvements within 1–2 weeks, with full results after 4–6 weeks.
Effects typically last 4–6 months, depending on muscle strength and grinding habits.
Yes. As the muscle becomes less active, it gradually reduces in size, creating a slimmer and more contoured jawline.
Discomfort is minimal. Most patients describe it as a quick pinch. The entire procedure takes 15–20 minutes.
