Masseter Botox: a gentle way against teeth grinding & tension headaches.

Nocturnal teeth grinding damages teeth and tenses the jaw. A targeted treatment of the chewing muscle can relieve the pressure.

The problem: bruxism

With bruxism, those affected clench and grind — often at night and unconsciously — with considerable force. The consequences range from worn-down teeth to jaw joint problems and tension headaches. The cause is often an overactive chewing muscle (musculus masseter).

How the treatment works

During the treatment, a muscle-relaxing agent is injected in a targeted way into the chewing muscle. This makes the muscle weaker, not non-functional — chewing remains possible, but the unconscious, extreme clenching force decreases. This relieves the teeth and jaw joint.

A double effect

Because the chewing muscle helps shape the face, a very strong masseter can visually create an angular, broad lower-jaw profile. The treatment therefore often also has a slightly face-harmonising effect.

Procedure & effect

  • Short treatment, usually a few minutes
  • The effect does not set in immediately, but over a few days
  • The effect is temporary — a top-up after a few months is common
  • No downtime, normal everyday life right afterwards

What the treatment is not

Masseter Botox treats the symptom, not necessarily the cause. If stress or a misalignment lies behind it, for example, that should be taken into account too. A combination with a grinding splint is often advisable — we discuss this individually.

Our conclusion

For many of those affected, masseter Botox is an effective, gentle relief — as part of a well-thought-out concept, not as an isolated quick fix.
