Botox treatment of the masseter
The masseter is one of the strongest muscles in the face. Treatment can ease teeth grinding and jaw discomfort and make the face look slimmer.

Why patients come to me
Your concern
In many people the jaw muscle is constantly overactive. This can lead to unconscious teeth grinding, jaw pain and tension. At the same time, a pronounced masseter can make the face look wider and more angular.
The treatment
Botulinum toxin is injected into the masseter on both sides of the jaw and relaxes the muscle. The treatment takes about 15 to 20 minutes and causes very little discomfort. Afterwards you can eat and drink normally.
Possible result
Teeth grinding and related discomfort can noticeably decrease. The face can also look slimmer, an effect that develops over several weeks. The effect usually lasts 4 to 6 months.

Masseter treatment can be combined with the upper-face areas. Package prices apply when combined in one session.

Translated from German.

„I had problems with grinding and strong clenching for a long time, especially when stressed. I often woke up with a tense jaw. Since the treatment I notice a big difference. I clench much less at night and wake up more rested.“

„For years I ground my teeth at night and clenched unconsciously during the day. After the masseter treatment the grinding has improved a lot and my jaw feels more relaxed. Over time my face has become a little slimmer and still looks natural.“
Good to know: masseter treatment in Berlin
The masseter is one of the strongest muscles in the body. It sits at the side of the jaw and is responsible for chewing, but also for unconscious teeth grinding and jaw clenching, medically called bruxism. If it is constantly overactive, it can contribute to headaches, jaw pain and dental damage.
Botox for teeth grinding: how does it work?
Botulinum toxin is injected into the masseter and relaxes the muscle without affecting normal chewing. This can reduce pressure on the teeth and tension in the jaw and neck. The effect usually lasts 4 to 6 months.
Face slimming: a slimmer facial profile
A pronounced masseter can make the face look wider. When the muscle is relaxed, it can reduce in size over several weeks and the facial profile can look slimmer.
Transparent pricing
Masseter treatment starts at €350. The price includes the original product, the medical treatment and a free follow-up after 14 days.
Frequently asked questions
How does the masseter treatment work?
After a short assessment, botulinum toxin is injected into the masseter with fine needles. The treatment takes 15 to 20 minutes and causes very little discomfort.
Can I eat and chew normally afterwards?
Yes, chewing function is preserved. For the first few hours just avoid very hard foods.
When will I see the first results?
Relaxation usually starts after 3 to 7 days. A slimmer-looking face develops over 6 to 8 weeks as the muscle gradually loses volume.
How long does the effect on teeth grinding last?
Usually 4 to 6 months.
Does it hurt?
Hardly. The needles are very fine; a slight feeling of pressure is possible and passes quickly.
How often should the treatment be repeated?
Initially every 4 to 6 months. For some people the intervals get longer over time.
Does the treatment replace a night guard?
Not necessarily. The treatment can be a useful addition to a night guard. If you have dental damage or jaw joint problems, a dental check-up is important.
