Masseter Botox NYC

The masseter is one of the strongest muscles in the body, responsible for clenching, chewing, and grinding. When this muscle becomes enlarged — whether from habitual teeth grinding (bruxism), genetics, or repetitive chewing — it can create a square, wide jawline that many patients find unflattering. Masseter Botox works by injecting a neuromodulator directly into the masseter muscle, temporarily relaxing the fibers and allowing the muscle to gradually slim down over several weeks.

At our practice, we favor Daxxify for masseter treatments because it consistently lasts longer than traditional Botox — even up to six months for many patients. This means fewer office visits, longer-lasting jaw slimming results, and sustained TMJ relief between appointments. Whether your primary goal is facial slimming, V-line contouring, or relief from jaw pain and teeth grinding, Daxxify in the masseter muscle delivers predictable, natural-looking outcomes.

Masseter Botox vs. Jaw Reduction Surgery

Patients researching jaw contouring inevitably encounter two options: Botox treatments in NYC and surgical jaw reduction (mandible ostectomy). Surgery involves shaving or reshaping the jawbone under general anesthesia, carries significant risks including nerve damage, and requires weeks of downtime with swelling and dietary restrictions. Masseter Botox, by contrast, is performed in minutes during a simple office visit with no anesthesia and essentially zero downtime.

For the vast majority of patients, Botox jaw slimming delivers the aesthetic improvement they are looking for without the permanence, expense, or surgical risk of an operation. Results develop gradually over two to four weeks, look entirely natural, and can be fine-tuned at follow-up visits. If a patient decides they prefer their original jaw shape, the effect simply wears off — an option that surgery can never offer.

Will masseter Botox change my smile?
When performed by an experienced, board-certified dermatologist, masseter Botox should not affect your smile. The masseter muscle is responsible for clenching and chewing, not for smiling. Dr. Akhavan uses precise injection placement to target only the masseter, leaving the surrounding muscles that control facial expression completely unaffected.

How many units of Botox do I need for jaw slimming?
Most patients require between 40 and 80 units total (split between both sides). The exact number depends on the size and strength of your masseter muscles. At our practice, $1,000 covers up to 80 units, and Dr. Akhavan determines the ideal dose during your consultation to ensure optimal slimming without over-treating.

Will masseter Botox affect my ability to chew?
No. The masseter is one of several muscles involved in chewing. Botox relaxes the muscle enough to reduce its bulk and relieve grinding, but you will still be able to chew food normally. Most patients notice no functional difference at all — only a slimmer, more contoured jawline.
