Masseter Botox has become one of the fastest-growing non-surgical treatments, used both for facial contouring and for jaw problems. At The Naderi Center for Plastic Surgery and Dermatology, our physicians see patients every week who want relief from jaw pain or teeth grinding, or who don’t like the fullness of their lower face. The treatment can ease those symptoms and soften a square jawline.
What You Need to Know About Masseter Botox
- Masseter Botox can reduce teeth grinding, jaw tension and TMD-related discomfort.
- It also slims the jawline by relaxing overactive masseter muscles.
- The effects usually persist for 3 to 6 months and get better with regular maintenance.
- The injections take only a few minutes, and most patients have no downtime.
- At The Naderi Center, injections are given by physicians only, whether the goal is symptom relief, a slimmer face or both.
Understanding the Masseter Muscle
The masseter muscle is one of the strongest muscles in the body, responsible for chewing and clenching. When overworked, it can lead to conditions like bruxism and temporomandibular joint disorder (TMD), along with cosmetic concerns such as jawline widening. Injecting Botox or another neuromodulator into the muscle calms that overactivity.
According to Dr. Shervin Naderi, a double board-certified facial plastic surgeon with more than 20 years of experience using Botox, “Masseter Botox is one of those treatments where medicine and aesthetics meet. We’re helping patients feel better while also giving them a more refined jawline.”
Benefits for Bruxism and Teeth Grinding
The most well-documented benefit of masseter Botox is its ability to reduce teeth grinding. Bruxism often leaves patients with tight jaws, worn enamel, headaches, and even fractured teeth. While mouthguards can help, they don’t address the root cause. Botox relaxes the muscle itself, significantly reducing the grinding reflex.
Many patients notice less tooth sensitivity, jaw soreness and tension headaches after one treatment, and some avoid dental repairs that chronic grinding and clenching would otherwise cause.

Masseter Botox Treatment for TMD Relief
TMD is another condition that responds favorably to masseter Botox. The temporomandibular joint connects the lower jawbone to the skull, and when this joint becomes inflamed or strained, it causes pain, stiffness, and even jaw locking. By relaxing the surrounding muscles, Botox helps restore function and reduce discomfort.
Common TMD symptoms, including jaw pain, headaches, limited jaw movement and even earaches, can improve with this minimally invasive treatment. For patients who have tried night guards, physical therapy or medications without success, masseter Botox is another option worth considering.
Cosmetic Botox Injections and Jawline Slimming
Masseter Botox also has a cosmetic use. Strong masseters can create a boxy, square jawline that looks disproportionate to the rest of the face. By gradually slimming these muscles, Botox gives the lower face a softer, more elegant V-shape.
Subtle, Natural Facial Contouring
When used for facial contouring, this treatment is often called jaw reduction or masseter reduction. Results develop gradually over a few weeks, so the change looks natural and understated.
Dr. Naderi explains, “We’re not just shrinking the muscle; we’re rebalancing the face. For some patients, a slimmer jawline brings out their cheekbones, makes their nose appear more delicate, and highlights the natural harmony of their features.”
Patient case
This patient received a total of 40 units of Botox, with 20 units injected into each masseter muscle to relax the overactive jaw muscles responsible for clenching and a widened lower face. Patients choose this treatment for jaw tension, for a slimmer lower face, or both. Results typically appear within 2 weeks and last 3 to 6 months, with no downtime.

Growing Popularity and Demand
In the past few years, requests for Botox in the masseter muscle have risen sharply. People on social media show how the injection narrows the lower face and dentists and oral surgeons prescribe it for patients who grind or clench their teeth. Because the injection both eases the dental problem as well as changes the face shape, more patients across the country now ask for it.
Treatment Process and Customization
At The Naderi Center, we typically inject 15–20 units per side of Botox into the masseter, depending on the strength of the muscle and the patient’s goals. The dose is adjusted for each patient to avoid over-treatment and keep chewing normal.
Results generally last three to six months, although some patients find that repeated treatments extend the duration as the muscle continues to weaken over time. Many patients schedule touch-ups two to three times a year to maintain their results.
Neurotoxin Options at The Naderi Center
The Naderi Center offers three FDA-approved neurotoxins: Botox®, Dysport®, and Daxxify®. Botox is the best known. Some patients prefer Dysport, which can take effect a little faster, or Daxxify, which was developed as a longer-acting option.
We explain how the three differ and recommend one based on what you want: jaw pain relief, a slimmer profile or both.
Dr. Naderi has more than 20 years of experience with Botox and performs his own injections.
Comfort, Pain Level, and Procedure Experience
Patients often ask whether the treatment hurts. Masseter Botox causes only mild discomfort. We apply numbing cream to the skin first, and the injections themselves are over quickly.
The treatment lasts under ten minutes. Patients feel a few quick pinches. Many leave the office and go straight back to work or to meet friends. No significant recovery time is needed.
Safety and Provider Training
At The Naderi Center, injections are given by physicians only, each with detailed knowledge of facial anatomy.
That knowledge of the anatomy is what keeps the result natural and helps prevent problems.
The practice is about half surgical and half non-surgical, so injectables are a large part of its everyday work, and patients travel from across the country for treatment.
Aesthetic Enhancements and Photogenic Results
The cosmetic change is a big part of the appeal. Many patients notice that their selfies and photos look more flattering as their jawline takes on a softer, more feminine or balanced appearance.
For men, Botox can also create a stronger yet less bulky look by defining the jawline while reducing excessive clenching.
“Patients are amazed at how one simple procedure can completely change the way they feel,” says Dr. Naderi. “When you take away the constant tension, pain, and bulk in the jaw, people often say they feel like a new person.”
Complementary Treatments at The Naderi Center
Masseter Botox can be combined with other treatments at The Naderi Center, such as non-surgical jawline contouring, other injectables and facial surgery, for a more balanced face overall.
During the consultation, we explain the results the patient should realistically expect, the possible side effects and the way masseter Botox can be complemented with other facial rejuvenation treatments.
Because it can relieve jaw symptoms and reshape the lower face with almost no recovery time, masseter Botox has become a routine part of facial care.
