Masseter treatment for teeth grinding: the jaw relief that also slims the face

The masseter is the muscle at the angle of the jaw, the one you can feel bulge when you clench. In people who grind or clench, particularly at night, it works far harder than it should. That means headaches, a tight jaw in the morning, worn teeth, and, over years, a squarer face as the muscle grows.

How the treatment works

A small dose of a muscle-relaxing injection is placed into the masseter on each side. The muscle does not stop working; it stops overworking. Chewing and speaking are unaffected. Clenching loses its force.

What changes, and when

• One to two weeks. The jaw feels looser. Morning tightness eases. Fewer tension headaches.
• Four to eight weeks. The muscle, no longer bulking under constant strain, gradually softens. The jawline looks less square. This is the part people did not come for and notice most.
• Three to five months. The effect wears off gradually. Repeat treatments tend to last longer as the muscle stays smaller.

The consultation for the masseter

This treatment is planned face to face, because the masseter varies more from person to person than any other muscle treated at the clinic. The practitioner asks you to clench and feels the muscle on each side, notes any difference between them, and asks about headaches, jaw clicking, tooth wear and whether a dentist has fitted a guard. If the jaw pain has a cause that is not the muscle, a joint problem for instance, that is said, and the treatment waits.

Doses, and why less is more

The masseter takes a larger dose than the areas of the upper face, but the clinic starts at the lower end of the range and reviews at two weeks. Too much, too soon, can make chewing feel like effort and, in a few people, thin the face more than they wanted. Starting light and building over two visits gives the same result with none of that. A dose that is right for you is then repeated, not increased, at each visit.

Aftercare

• No pressing or massaging the jaw for the rest of the day, and no lying face down that night.
• Nothing very chewy for a day or two: the muscle is settling and does not need the work.
• Keep wearing a night guard if you have one; the treatment lowers the force, the guard protects the teeth.
• A review at two weeks, so the dose can be adjusted before the next visit.

Signs it is time for the next one are the same as the signs that brought you in: a tighter jaw in the morning, a headache that starts at the temples, and a squareness returning at the angle of the jaw. Most people find those signs take four months or more to come back, and longer with each treatment.

What it costs, and how the cost is judged

The masseter is priced as its own area, and the price is on the treatments page beside the others. Judged against a night guard replaced every year, or against the dentistry that years of grinding lead to, most people find it reasonable; judged against the headaches it removes, more so. The clinic does not bundle it with anything, and the dose is set for the muscle rather than for the price, which is why a first visit is followed by a review rather than by a larger dose.

• A consultation first, always, because the dose depends on the muscle and the aim.
• A review at two weeks, part of the price rather than an extra.
• Repeats when the signs return, not by the calendar alone.

This treatment is planned in a consultation, not booked cold, because the dose depends on the size of the muscle and on what you want from it: relief, a softer jaw, or both.
