While BOTOX is primarily known for its wrinkle-smoothing benefits, it has other notable applications. When injected into the masseter (chewing) muscles, for example, it can slim your face and relieve temporomandibular joint (TMJ) symptoms. If you are wondering, "What is masseter BOTOX?" and what it can do for you, this blog post is just for you.

Masseter BOTOX® Before & After

Before & After Masseter BOTOX

What Is Masseter BOTOX?

Clenching or grinding your teeth can cause your masseter muscles to become overdeveloped. This creates a square facial shape and often leads to tightness and pain when chewing or opening your mouth. Injecting BOTOX into the masseter eases these symptoms and slims your lower face by relaxing the muscles.

Masseter BOTOX for Round Face Contouring

A round face isn't always due to baby fat! Sometimes, it results from enlarged masseter muscles, which can add width to your face shape. Masseter BOTOX reduces the bulkiness created by the masseters, allowing the muscles to shrink to a more normal size. The result is a tapered, V-shaped jawline and more harmonious facial proportions.

Relief for TMJ Symptoms

Beyond the cosmetic benefits, BOTOX can relieve the jaw pain, tension, and limited mobility that often comes with TMJ. Patients suffering from TMJ may alleviate these uncomfortable symptoms as BOTOX curtails the excessive jaw clenching and teeth grinding (bruxism). A 2012 study found that BOTOX injections significantly decreased discomfort and increased range of movement, with improvements persisting after 3 months.

How Many Units of BOTOX for Masseter Reduction?

On average, patients need 20 to 30 units per side to treat enlarged masseters. How many units you actually need will vary based on the size of the muscle, the degree of the improvement desired, and other factors. When you come in for a consultation, we will evaluate your face and create a treatment plan specific to your needs.

How Long Does Masseter BOTOX Last?

The effects of masseter BOTOX usually become noticeable within a few days to a week after treatment and can last anywhere from 3 to 6 months. Patients typically book a maintenance session before the effects wear off to sustain their results.

How Much Is Masseter BOTOX?

The cost of masseter BOTOX can vary depending on factors such as the provider's expertise, geographic location, and the number of units required. On average, BOTOX ranges from $10 to $20 per unit, with total treatment costs typically ranging from $500 to $1,000 per session. While this may seem costly, many individuals find the investment worthwhile for the noticeable improvements in facial esthetics and TMJ symptom relief.
