Masseter Botox in San Antonio, TX
Clenching, jaw tension, or a jawline that looks wider than you would like? Masseter Botox at Jovem Med Spa in San Antonio relaxes the powerful jaw muscle to ease TMJ discomfort and teeth grinding — while gently slimming and softening the lower face. It is a quick, physician-led treatment with both therapeutic and aesthetic benefits.
What Is Masseter Botox?
Masseter Botox is the targeted injection of a neurotoxin (Botox®, Dysport®, or Daxxify®) into the masseter — the large muscle at the back of your jaw that powers chewing and clenching. By relaxing this muscle, the treatment relieves the tension behind TMJ pain, jaw clenching, and teeth grinding (bruxism). Over time the masseter also slims, softening a square or overdeveloped jawline for a more oval facial shape. It is both a medical and cosmetic treatment in one.
How Masseter Botox Works
When you clench or grind, the masseter muscle works overtime — which can cause jaw pain, tension headaches, worn teeth, and a bulkier lower face. A few precise injections temporarily relax the muscle so it cannot contract as forcefully. This eases clenching and the discomfort that comes with it, and because the under-used muscle gradually shrinks, the jawline becomes slimmer over the following weeks. Your provider tailors the dose to your muscle strength and goals.

Who Is a Good Candidate for Masseter Botox?
Masseter Botox is ideal for adults in San Antonio who clench or grind their teeth, experience TMJ-related jaw pain or headaches, or want to soften a wide, square jawline. It often complements a night guard for bruxism. During your consultation, our medical team examines your jaw muscles and discusses your goals to determine whether you are a good candidate and how much product you will need.
What to Expect During Treatment
Masseter Botox takes about 10 to 15 minutes. Your provider injects each masseter muscle with a few small injections — most clients describe only a quick pinch — and there is no downtime afterward. You can return to your day right away. Jaw-tension relief often begins within a few days, while the slimming, contouring effect develops gradually over several weeks as the muscle relaxes.

How Long Does Masseter Botox Last?
Masseter Botox typically lasts about three to six months. Because the masseter is a strong, frequently used muscle, results may wear off a bit sooner at first; with repeat treatments the muscle often stays relaxed longer and the slimming effect becomes more lasting. Most clients schedule maintenance two to three times a year to keep both the comfort and contouring benefits.
