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

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.

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.

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.

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.

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.
