Masseter Botox is one of the fastest-growing requests at our Downers Grove clinic — and for good reason. A single 15-minute appointment can quiet a clenching jaw, ease tension headaches, and slowly slim a square jawline.
What Is the Masseter?
The masseter is the powerful chewing muscle on the side of your face. When it's overactive — from chronic clenching, grinding (bruxism), or just genetics — it bulks up like any other muscle, widening the lower face and creating constant tension.
What Masseter Botox Does
- Relaxes the muscle so it can't clench or grind as forcefully
- Relieves TMJ pain, jaw soreness, and tension headaches
- Gradually slims the jawline as the muscle atrophies over months
- Protects your teeth and dental work from grinding damage
How Many Units?
20–30 units per side (40–60 total) is the typical starting dose. Larger or more overactive muscles may need more. See our full Botox units guide for context.
Results Timeline
- Week 1–2: Clenching and grinding noticeably reduce. Jaw feels looser.
- Month 1–2: Tension headaches and morning soreness improve.
- Month 2–4: Visible slimming as the muscle reduces in size.
- Month 4–6: Results peak. Re-treatment typically every 4–6 months.
Is It Right for You?
Great candidates include people who:
- Wake up with a sore jaw or have a night-guard for grinding
- Have chronic tension headaches starting at the temples
- Feel their jaw is wider or more square than they'd like
- Have been told by a dentist they're cracking teeth or wearing enamel
What It Costs
At $12–$18 per unit in the Downers Grove market, masseter Botox typically runs $500–$1,100 for both sides. See our Botox cost guide for full pricing.
