Masseter Botox in Murrieta & Temecula: TMJ Relief + Facial Slimming
If you’ve ever caught yourself clenching your jaw, waking up with headaches, or feeling like your face looks wider than you’d like—your masseter muscle might be the reason.
Masseter Botox is one of the most underrated treatments because it does two things at once:
✔ Relieves jaw tension and TMJ symptoms
✔ Slims and softens the lower face
Let’s break it down.
What Is the Masseter Muscle?
The masseter is the large muscle located at the back of your jaw. It’s responsible for chewing—but it can also become overactive from:
Teeth grinding (bruxism)
Jaw clenching (especially from stress)
TMJ dysfunction
When this muscle is overworked, it can grow larger (like any muscle), creating a wider, more square jawline.
What Is Masseter Botox?
Masseter Botox involves injecting a small amount of neurotoxin (like Botox, Xeomin, or Jeuveau) directly into the masseter muscle.
This works by relaxing the muscle, which:
Reduces clenching and grinding
Relieves jaw pain and tension
Softens the appearance of a bulky jawline over time
TMJ Relief: How It Helps
For clients dealing with TMJ symptoms, this treatment can be a game changer.
Common symptoms that improve:
Jaw pain or tightness
Clicking or popping
Headaches (especially tension headaches)
Teeth grinding (day or night)
By reducing the strength of the muscle, Botox helps break the cycle of overuse and inflammation.
Facial Slimming Benefits
This is where the aesthetic magic happens ✨
When the masseter muscle relaxes and shrinks over time, the lower face becomes:
Softer
More tapered
Less square
Results develop gradually, typically over 4–8 weeks, creating a natural slimming effect without surgery.
What to Expect During Treatment
Treatment time: ~15 minutes
Discomfort: Minimal (quick pinches)
Downtime: None
You can return to normal activities right away
Most clients need treatment every 3–4 months to maintain results.
How Many Units Do You Need?
This varies based on muscle strength and goals, but typical dosing ranges:
20–30 units per side for aesthetic slimming
25–40+ units per side for TMJ relief
A consultation is key to customizing your treatment.
When Will You See Results?
TMJ relief: Often within 1–2 weeks
Slimming effect: Gradual, with full results at 6–8 weeks
Who Is a Good Candidate?
You may be a great candidate if you:
Clench or grind your teeth
Have jaw pain or TMJ symptoms
Feel your face looks too wide or “bottom heavy”
Want a softer, more contoured jawline without filler or surgery
