How does Masseter Botox work
Once injected into the masseter on each side, the toxin reduces the muscle's ability to contract forcefully. This quickly eases clenching and grinding and the tension that comes with them. Over the following weeks and months, using the muscle less causes it to gradually reduce in size, which subtly slims the jawline for a softer lower-face contour.
An overactive or enlarged masseter causes both discomfort and a widened jaw. Relaxing it works on several levels:
- Reduced contraction force — eases the intensity of clenching and grinding
- Muscle slimming — with less use, the muscle gradually reduces in bulk over months
- Tension relief — lowers the strain that contributes to jaw ache and headaches
- Jaw refinement — a slimmer masseter softens the width of the lower face
Patient Journey
What to expect
Consultation
Every treatment begins with a consultation. Your practitioner feels the masseter as you clench to gauge its strength and size, discusses whether your goal is relief from grinding, jaw slimming or both, reviews your medical and dental history and agrees the dose before proceeding.
Preparation
- Avoid alcohol for 24 hours before treatment
- Pause non-essential blood thinners for a few days where safe
- Arrive with clean skin over the jaw area
- Let your practitioner know if you wear a night guard for grinding
- Have realistic expectations that slimming develops gradually over months
Treatment
Your practitioner will ask you to clench so the muscle can be located and mapped on each side. After cleansing the skin, a few injections are placed into the body of the masseter at the angle of the jaw using a fine needle. Each feels like a brief pinch and the appointment takes around fifteen minutes. No anaesthetic is needed and you can return to normal activities immediately with standard aftercare.

Who performs Masseter Botox
Frequently asked questions
Yes. Relaxing the masseter commonly reduces clenching and grinding and the tension and headaches that go with them, and can protect the teeth from wear.
Around four to six months. Repeated treatment maintains the relief and supports gradual slimming.
Relief from grinding comes within a week or two, while visible slimming develops gradually over several weeks to months and builds with repeat sessions.
You may notice mild chewing fatigue for a week or two at first, which settles as the muscle adapts.
No, just follow the aftercare advice for the first day.
