Masseter Botox Guide: Jawline Slimming and TMJ Relief
Whether you’re dealing with a heavy, square jawline or physical discomfort from a sore jaw, it can be frustrating. Masseter Botox is a precision treatment that solves both issues simultaneously, relaxing the specific muscle responsible for bulk and bite force. Dr. Nathan Brought is a board-certified plastic surgeon who brings expertise and precision to masseter Botox, providing a slim jaw without affecting your smile.
How Masseter Botox Delivers Slimming and Relief
Botox works as a neuromodulator, blocking nerve signals and forcing the overactive masseter muscle in the jaw to relax. Relaxing the muscle reduces its size over time, leading to a narrower lower face, much like a muscle you stop working out at the gym. This same relaxation also stops the involuntary grinding that causes pain, protecting teeth and reducing morning headaches.
Does Masseter Botox Help TMJ?
Yes, masseter Botox can help the temporomandibular joint (TMJ) and teeth grinding. While it is an off-label use, it is widely accepted clinically for reducing the bite force that strains the TMJ. Specifically, masseter Botox can provide symptom relief from clicking and popping in the jaw, fewer tension migraines and less wear and tear on tooth enamel.
Medically, masseter Botox is ideal for patients who have tried mouthguards at night without success. This treatment can also be helpful for those who unintentionally clench their jaw during the day due to stress.
The Cosmetic Side: Masseter Botox Jaw Slimming
In addition to masseter Botox for TMJ, this treatment offers jaw slimming benefits. Masseter Botox can help create a visual transformation of your jawline, shifting it from a square or boxy lower face to a softer, heart-shaped or V-line contour. For women, cosmetic masseter Botox can reduce jaw width, making the face appear more feminine and youthful. Men can also benefit from masseter Botox, as Dr. Brought will adjust dosage to reduce bulk without removing the masculine jawline structure.
What to Expect From Masseter Botox Treatment
Specific unit estimates for Botox can vary depending on your treatment goals. For example, Botox for TMJ may require more units per side than for a slimming effect.
For pain relief, clients can usually feel a difference within one to two weeks as the muscle rests. Slimming results can be visible within four to six weeks, allowing time for the muscle to shrink. Results typically last four to six months before the treatment needs to be repeated. Dr. Brought can work with you to design a regular treatment schedule to maintain results.
Why Choose a Board-Certified Surgeon Over a Med Spa?
The masseter is located near the critical smile muscles, the risorius, and incorrect injection depth can lead to a crooked smile or drooling. Dr. Brought is a board-certified doctor of osteopathic medicine (DO) and a Fellow of the American College of Osteopathic Surgeons (FACOS) with knowledge and expertise in facial anatomy. He and his team at Southern Plastic & Reconstructive Surgical Institute follow a conservative dosing technique, using the exact right amount of units to save you money and ensure natural movement.
