Masseter Botox As a Solution To Improve Jaw Appearance

The masseter muscle is a chewing muscle that is on the sides of the jaw. Sometimes your muscle mass increases, which is known as masseter hypertrophy. The main causes of masseter hypertrophy are bruxism, excessive use of chewing gum, and stress. Masseter Botox provides a solution for these ailments.

In addition, there are people who, for a matter of facial constitution, have these overdeveloped muscles, producing a more prominent jaw and a square face, which can be unaesthetic.

Botulinum toxin, better known as Botox, is a drug that weakens the action of the muscle where it is injected. The implementation of jawline Botox in strategic spots of the masseter muscles helps to relax them and stylize the mandibular contouring.

This treatment achieves a sharpening of the chin and a thinning of the lower third, besides alleviating bruxism symptoms.

What is bruxism?

Bruxism is the main cause of masseter hypertrophy. It appears when the jaw contracts unconsciously due to stress.

It leads to jaw pain and swelling, joint sounds, episodes of fatigue and muscle stiffness, hypersensitivity, worn teeth, headache, and temporomandibular disorder. All these symptoms improve with the application of jaw botox.

The causative factors of masseter muscle hypertrophy include poor hygiene-dietary habits, anxiety, stress, a neurotic oral habit (gum abuse), nocturnal bruxism, temporomandibular joint disorders, among others.

How long does it take for masseter Botox to take effect?

During the first 3-5 days, you will notice a subtle change in muscle tone (weakness when consciously clenching the teeth). The muscle will begin to soften from the first week on, then the masseter will feel soft even when clenching the teeth. These changes mean that the muscle is responding to jaw slimming Botox as expected.

Following 2 or 4 weeks, the atrophy of the masseter muscle is evident and the visual change in muscle volume can already be seen, with the face thinner and sharper. The maximum masseter Botox before and after effect occurs after 3 months. If Botox is not applied repeatedly, the muscle tone and volume will get back to their former state slowly.

As masseter Botox sessions are repeated, at recommended intervals, the effect on the muscle and the efficacy of the treatment increases. Therefore, additional treatments may be needed to permanently reduce excess masseter activity.

Experts recommend undergoing the masseter Botox treatment after 4-6 months and then doing it again 4-6 months afterward.

You will get in return:

  • Masseter reduction
  • A jawline that seems narrower
  • Decreased muscle pain and discomfort associated with bruxism
  • A more stylized face
  • A face that looks slimmer overall

And most importantly, the application of jaw slimming Botox does not affect chewing or speech in any case.

While the bruxism treatment with botulinum toxin is valid for the vast majority of people who suffer from teeth clenching, it is mandatory for patients with issues related to the temporomandibular joint or teeth alignment. This time, they should go to another specialist to go through special treatment. Further, the masseter Botox cost is relatively low, around euros, which can be affordable for many people in Europe and US.
