Vou ter dificuldade em mastigar?

Não, com dose adequada. Reduz-se a força excessiva de contração, não a função. Pode notar-se alguma sensação de menor força nos primeiros dias, sobretudo com alimentos muito duros, que normaliza rapidamente.

Serve para a dor de cabeça ao acordar?

Frequentemente sim, quando essa dor tem origem na tensão do masseter e do temporal durante o sono. A avaliação em consulta ajuda a perceber se é essa a causa — nem todas as cefaleias matinais são de origem muscular.

É o mesmo produto usado nas rugas da testa?

É a mesma substância, aplicada noutro músculo e em doses diferentes. O masseter é um músculo bastante mais potente e exige quantidades superiores às usadas no terço superior da face.

Botulinum Toxin for Bruxism and the Masseter

Botulinum toxin applied to the masseter, with two goals that often go together: relieving bruxism and slimming the jawline.

What bruxism is

Bruxism is the involuntary grinding or clenching of the teeth, mainly during sleep. It causes tooth wear, jaw joint pain, morning headaches and muscle tension in the face and neck.

Over time, hypertrophy of the masseter muscle, which grows larger from overwork, also visibly widens the lower third of the face.

How the treatment helps

Botulinum toxin applied to the masseter reduces the muscle's contraction force. This relieves the load on the teeth and joint, reduces pain and, as the muscle is used less, it shrinks in volume.

It is important to be clear: the treatment acts on the consequence, not the cause. Bruxism often stems from stress, anxiety or sleep disorders, and these should be addressed in parallel. In many cases, coordination with your dentist is recommended.

Aesthetic effect

Reducing masseter volume slims the jawline and softens a square lower face. For people seeking this effect without bruxism, the procedure is equally possible, with the same prior assessment.

The change is gradual and becomes evident after four to eight weeks.

Duration and maintenance

Symptom relief usually lasts between four and six months. The slimming effect tends to last longer with repeated sessions, as the muscle remains less active.

Frequently asked questions

Will I have trouble chewing?

No, with the right dose. It reduces excessive contraction force, not function. You may notice slightly less strength in the first few days, especially with very hard foods, which quickly returns to normal.

Does it help with morning headaches?

Often, yes, when the headache comes from tension in the masseter and temporal muscles during sleep. The consultation helps establish whether that is the cause, as not all morning headaches are muscular.

Is it the same product used for forehead lines?

It is the same substance, applied to a different muscle at different doses. The masseter is a much stronger muscle and requires larger amounts than those used in the upper face.
