Masseter Botox: A Comprehensive Guide to Slimmer Jawlines and Reduced Bruxism


Masseter botox is a non-surgical cosmetic treatment that involves injecting botulinum toxin into the masseter muscles, located on each side of the jaw. These muscles are responsible for chewing and clenching, and overactivity can lead to a square-shaped jawline, bruxism (teeth grinding), and facial pain.

Benefits of Masseter Botox

Slimmer Jawline: Masseter botox can relax the masseter muscles, causing them to atrophy slightly. This can result in a slimmer, more defined jawline.

Reduced Bruxism: Bruxism is the involuntary grinding or clenching of teeth, often occurring during sleep. Masseter botox can help to relax the masseter muscles, reducing the frequency and severity of bruxism.

Improved Facial Symmetry: Overactive masseter muscles can cause the jawline to appear asymmetrical. Masseter botox can help to relax these muscles, creating a more balanced and symmetrical facial appearance.

Reduced Facial Pain: Overactivity or tightness in the masseter muscles can cause facial pain, headaches, and jaw pain. Masseter botox can help to relax these muscles, reducing pain and improving overall facial comfort.


The masseter botox procedure is relatively quick and simple. A topical anesthetic may be applied to numb the area, and then small amounts of botulinum toxin are injected into each masseter muscle. The number of injections will vary depending on the size of the masseter muscles and the desired results.


Masseter botox is generally considered to be an effective treatment for reducing the size of the masseter muscles, improving facial symmetry, and reducing bruxism. The results of treatment typically last for three to four months, after which the muscles will gradually regain their strength.

Side Effects

Masseter botox is a safe procedure, but there are some potential side effects, such as:

Temporary bruising or swelling at the injection sites
Temporary weakness in the jaw muscles
More serious side effects, such as difficulty swallowing or speaking, are very rare.


The cost of masseter botox will vary depending on the provider, the geographic location, and the number of injections required. However, it is generally considered to be a more affordable option than surgical jaw reduction.


Masseter botox is a safe and effective treatment for a variety of cosmetic and functional concerns related to the masseter muscles. If you are considering this treatment, be sure to consult with a qualified and experienced provider.
