Masseter Muscle Treatments in Coral Gables,Miami for Jawline Contouring, TMJ Relief, and Teeth Grinding
The masseter muscles are the powerful muscles located at the sides of the jaw, responsible for chewing and clenching. Overactivity of these muscles can lead to a square or bulky jawline, TMJ (temporomandibular joint) discomfort, teeth grinding (bruxism), and facial tension.
At RDYMD in Coral Gables & Miami, Dr. Rafael Diaz-Yoserev, MD, FACS, offers physician-supervised neuromodulator treatments (Botox® or Xeomin®) that target the masseter muscles, helping patients achieve jawline slimming, improved facial harmony, and relief from TMJ-related discomfort.
Causes of Masseter Hypertrophy and Jawline Concerns
Excessive masseter muscle activity can result from:
Chronic teeth grinding or clenching (bruxism)
TMJ disorders causing muscle overuse and jaw tension
Genetics or naturally strong jaw musculature
Stress-related repetitive jaw movements
Benefits and What to Expect
Patients receiving masseter treatments can expect:
- A slimmer, more defined jawline and enhanced facial balance
- Relief from TMJ pain, tension headaches, and jaw discomfort
- Reduced teeth grinding and nighttime clenching
- Safe, minimally invasive treatment with little to no downtime
How Masseter Botox/Xeomin Works?
Neuromodulator injections (Botox® or Xeomin®) temporarily relax the masseter muscles, reducing their size and activity over several weeks. Benefits include:
Jawline Slimming & Contouring: Relaxed masseters create a softer, more oval facial shape
TMJ Relief: Reduces muscle tension, alleviating jaw pain, headaches, and discomfort
Teeth Grinding Reduction: Helps decrease bruxism and nighttime clenching
Non-surgical & Minimally Invasive: Quick treatment with minimal downtime
Dr. Diaz-Yoserev often prefers Xeomin® for masseter treatments due to its purified formulation, offering precise dosing and predictable results while minimizing diffusion into nearby muscles.
we’re here to all your questions
Will masseter Botox affect my ability to chew or eat?
No. Masseter Botox relaxes excessive clenching, but it does not stop normal chewing. You may feel slightly weaker when chewing very tough foods for the first 1–2 weeks, but this is temporary and mild. Most patients experience improved comfort and reduced tension.
How long do masseter Botox results last?
Masseter Botox typically lasts 4–6 months, sometimes longer with regular treatments. Jawline slimming becomes noticeable around 4–8 weeks, while TMJ symptom relief often begins sooner. Consistent maintenance leads to longer-lasting contouring and comfort.
Is masseter Botox safe for treating TMJ and teeth grinding?
Yes. When performed by a medically trained injector, masseter Botox is a safe and widely used treatment for TMJ pain, jaw tension, clenching, and bruxism. At RDYMD, we focus on precise dosing to ensure both effective relief and a natural-looking jawline.
How soon will I notice improvement in jawline shape or TMJ symptoms?
Most patients begin to feel relief from jaw tension or teeth grinding within 1–2 weeks. Visible jawline slimming typically appears around 4–8 weeks, with full results at 10–12 weeks. Individual results may vary depending on muscle strength and treatment plan.
