What does masseter Botox achieve?
The masseter is the powerful chewing muscle on the side of the jaw. If it is overactive — for example through nocturnal clenching and grinding (bruxism) or constant tensing under stress — this can lead to jaw pain, tension headaches and worn teeth. When botulinum toxin is injected specifically into the masseter, its strength temporarily subsides. This can ease the symptoms; because the muscle also becomes somewhat slimmer, the lower half of the face appears finer and more relaxed in many people.
When is the treatment advisable?
- Teeth grinding / bruxism — especially at night, often first noticed by a dentist or partner.
- Jaw pain and tension headaches that are linked to strong clenching.
- A strong jaw contour that should appear more harmonious (aesthetic aspect).
Whether the treatment is an option for you — and whether a dental assessment (e.g. a grinding splint) beforehand makes sense — we discuss openly in the medical consultation.
How the treatment works
Medical consultation
We palpate the chewing muscle, discuss your symptoms and inform you about the benefits, limits and alternatives.
Injection
Using fine needles, a few points are placed into the masseter on both sides — this takes only a few minutes and is well tolerated.
Effect
The relief builds up over one to two weeks. A visible slimming of the contour, if desired, often only becomes apparent after several weeks.
Check-up
On request, we assess the result together and make gentle adjustments.
Price
Billing is transparent according to the German Scale of Medical Fees (GOÄ) based on the amount of botulinum toxin required. Since the chewing muscle is considerably larger than the small facial muscles, the price is higher than that of a single wrinkle treatment — before the treatment you receive a clear, binding overview with no hidden costs.

Frequently asked questions
Does masseter Botox really help against teeth grinding?
In many of those affected, the pressure during clenching and grinding subsides because the chewing muscle temporarily develops less force. The treatment does not replace a dental assessment — it is often a sensible addition to a grinding splint. We discuss this individually.
How long does the effect last?
Usually around three to six months. Afterwards the body fully breaks down the active substance; a top-up is possible at any time. With regular treatment the muscle often becomes permanently somewhat calmer.
Can I still chew normally afterwards?
Yes. The dosing is such that normal chewing and speaking are preserved — what is reduced is the excessive constant tension, not the chewing function.
Does the treatment hurt?
The injections are given with very fine needles and are usually felt only as a brief prick. Anaesthesia is generally not necessary.
What side effects are possible?
Small bruises or a feeling of pressure at the injection sites are possible, rarely a temporary sensation of chewing fatigue. For this reason the treatment is carried out exclusively by a doctor and after detailed information.
As with any medical treatment, side effects and risks cannot be ruled out. We inform you about individual risks, possible alternatives and the course you can expect in a personal medical consultation before every treatment.
