What Is Masseter Botox®?
Masseter Botox® is a non-surgical treatment that uses small, targeted injections of botulinum toxin into the masseter muscle — the large muscle responsible for chewing and jaw clenching. When injected by a trained clinician, Botox® temporarily relaxes the muscle, reducing the intensity of involuntary grinding and clenching that causes chronic jaw pain, headaches, and long-term damage to your teeth.
Unlike general cosmetic Botox®, this treatment is administered with a precise dental understanding of jaw anatomy, bite mechanics, and occlusal function. At Lazare Biomimetic Dentistry & Smile Design, every injection is performed by Dr. Marc Lazare himself — not a nurse or aesthetician.

Facts About Masseter Botox for TMJ & Bruxism
Is This Treatment Right for You?
You may be a candidate for Masseter Botox® if you experience any of the following:
— Chronic jaw pain or soreness, especially in the morning
— Frequent tension headaches originating near the temples or jaw
— Teeth grinding (bruxism) during sleep or periods of stress
— A tight, locked, or fatigued jaw after eating or speaking
— Visible jaw muscle enlargement causing facial asymmetry
— Worn, chipped, or cracked teeth from grinding
— Discomfort that has not resolved with nightguards alone
If you recognize yourself in this list, a consultation with Dr. Lazare will determine whether Masseter Botox® is the right solution — or whether a combined approach is more appropriate for your specific condition.
What to Expect During Treatment
The procedure is straightforward, minimally invasive, and completed entirely in-office — typically in under 20 minutes.
During your appointment, Dr. Lazare will identify the precise injection points based on your individual masseter muscle anatomy and the severity of your condition. A fine needle delivers small amounts of Botox® directly into the muscle on each side of the jaw. Most patients describe the sensation as a brief, mild pinch.
There is no anesthesia required and no downtime. You can return to your normal schedule immediately following treatment. Results begin to appear within 3 to 7 days as the muscle gradually relaxes, with full effect typically visible within two weeks.
How Long Do Results Last?
Most patients experience significant relief from jaw pain, headaches, and grinding within the first two weeks following treatment. The results of Masseter Botox® typically last between 3 and 6 months, depending on the individual's muscle mass, metabolism, and the severity of their bruxism.
With repeated treatments over time, many patients find that the masseter muscle gradually reduces in size and activity — meaning results can become longer-lasting with each session. Dr. Lazare will recommend a treatment schedule tailored to your specific needs and response to the injections.

Why This Treatment Belongs in a Dental Office
Masseter Botox® is widely available at medical spas and aesthetic clinics. But the jaw is not simply a cosmetic concern — it is a complex functional structure that directly affects your bite, your teeth, and your long-term oral health.
Your Jaw. Your Bite. Your Long-Term Health.
Dr. Lazare approaches every case with a complete understanding of your dental health — identifying whether bruxism is related to bite misalignment, stress, sleep patterns, or other contributing factors. The result is not just temporary relief. It is a treatment that fits within a broader strategy to protect your teeth and your jaw for the long term.
Often More Effective When Combined
For many patients, Masseter Botox® works best as part of a comprehensive TMJ management plan. Depending on your diagnosis, Dr. Lazare may recommend combining this treatment with one or more of the following:
— Custom Nightguards — to protect teeth from grinding while the muscle relaxes
— Infrared Light TMJ Therapy — to reduce inflammation and promote healing in the joint
— Biomimetic Restorations — to repair teeth already damaged by chronic grinding
A combined approach addresses both the symptom and the source — providing lasting relief rather than temporary management.
