Treatment
Therapeutic Botox (botulinum toxin) injections into the jaw muscles are a highly effective, minimally invasive treatment for chronic jaw clenching, bruxism, and TMJ-related headaches. Results typically last 3–6 months and the procedure takes under 20 minutes.
How It Works
Botulinum toxin (Botox) works by temporarily blocking the nerve signals that cause muscle contraction. When injected into the masseter (the large chewing muscle) and temporalis muscles, it reduces the force of clenching and grinding — without affecting normal chewing or speech.
This reduction in muscle force relieves the pain and pressure on the jaw joint, reduces headaches caused by muscle tension, and protects teeth from further grinding damage. It is particularly effective for patients who have not achieved adequate relief from splint therapy alone.
Who It Helps
Benefits
Most patients notice significant reduction in jaw pain and headaches within 1–2 weeks of treatment.
By reducing the force of clenching, Botox helps prevent further tooth wear, cracking, and damage to dental restorations.
As the masseter reduces in size with repeated treatment, the lower face gradually softens — a welcome side effect for many patients with a square or bulky jaw profile.
Effects typically last 3–6 months. With repeated treatment, many patients find the interval between treatments extends.
The injections are administered with a fine needle and are well-tolerated by most patients. Topical anaesthetic is available if preferred.
What to Expect
We assess your jaw muscles, bite, and symptoms to confirm Botox is appropriate and identify the optimal injection sites and dosage.
Botox is injected into the masseter and/or temporalis muscles using a fine needle. The procedure takes 15–20 minutes.
The muscle-relaxing effect develops gradually over 1–2 weeks. Full effect is typically seen at 2–4 weeks.
We review your response at 4–6 weeks and schedule maintenance treatments every 3–6 months as needed.
