A Head & Neck Specialist's Approach to Jaw Tension Relief

Few injectors know the jaw as thoroughly as a head and neck surgeon. Dr. Amir Moradi is double board-certified in facial plastic surgery and otolaryngology–head and neck surgery, giving him a detailed understanding of the muscles, nerves, and joints that shape the lower face.

Beyond his surgical training, Dr. Moradi has served as an investigator in numerous clinical trials for neurotoxins and dermal fillers. He also consults for leading aesthetic companies, including AbbVie, Evolus, Merz, and Galderma. That research background informs every masseter treatment plan he and his team design.

What Is Masseter BOTOX®?

Masseter BOTOX® is an injectable treatment that relaxes the masseter, the large chewing muscle at the angle of the jaw. A small dose of neuromodulator temporarily limits how forcefully the muscle contracts, easing clenching while leaving normal chewing and speaking intact.

"TMJ" refers to the temporomandibular joint itself, while temporomandibular disorders (TMDs) describe the conditions that cause pain in the joint and surrounding muscles. According to the National Institute of Dental and Craniofacial Research, TMDs include more than 30 conditions, and disorders of the chewing muscles are one of the three main categories.

Over time, chronic clenching can also enlarge the masseter, creating a wider, squarer lower face. Relaxing the muscle lets it gradually slim, which is why many patients notice a softer jawline as a secondary benefit.

Benefits of TMJ and Masseter BOTOX®

Patients choose masseter injections for both comfort and aesthetics. Potential benefits include:

Relief from jaw pain, tightness, and fatigue
Less nighttime clenching and teeth grinding (bruxism)
Fewer tension headaches linked to jaw strain
Reduced wear on teeth and dental work
A slimmer, softer jawline over time
A quick in-office visit with no downtime

The Cleveland Clinic notes that providers may recommend BOTOX® for more severe teeth grinding, often alongside a night guard or other dental care.

Are You a Candidate for TMJ BOTOX® in San Diego?

You may be a good candidate for TMJ BOTOX® in San Diego if you wake with a sore or tired jaw, clench during stressful moments, or have been told you grind your teeth at night. Patients who want a softer jawline without surgery are also often well suited.

Treatment is not recommended during pregnancy or breastfeeding, or for people with certain neuromuscular conditions. Because jaw pain can have several causes, Dr. Moradi reviews your history and symptoms carefully and may recommend coordinating with your dentist.

What to Expect From Masseter BOTOX® Treatment

Consultation and Cost

Your visit begins with a consultation at our San Diego-area practice, where the team evaluates your jaw muscles, bite, and goals. The cost of masseter BOTOX® depends on the number of units needed, since stronger muscles typically require a larger dose. You'll receive a personalized quote before treatment, and new patients can take $50 off their first service.

The Treatment Experience

Masseter injections take only about 10 to 15 minutes. After cleansing the skin, your injector places a few precise injections into each masseter muscle. Most patients describe the sensation as a brief pinch, and you can return to work or daily activities right away.

Results and Maintenance Timeline

Clenching relief often begins within a few days to two weeks. Jawline slimming develops more gradually as the muscle relaxes, usually becoming visible over several weeks. Results typically last three to six months, and many patients find that regular maintenance sessions help them enjoy longer-lasting relief.

Related Treatments for Jawline and Facial Balance

Masseter injections pair well with other treatments that refine the lower face. Dr. Moradi may suggest BOTOX® for forehead lines or neck bands, dermal fillers to define the chin and jaw, chin augmentation, or neck liposuction for a more sculpted profile.

Careful dosing allows you to chew, speak, and smile normally. Some patients notice mild chewing fatigue with tough foods for the first few weeks.

Temporary bruising, tenderness, or headache at the injection sites are most common. Rare risks include smile asymmetry or chewing weakness, which Dr. Moradi minimizes through precise placement.
