Botox vs. Splint for TMJ
Two leading non-surgical TMJ remedies—Botox injections and occlusal splints (night guards)—work by different mechanisms. Understanding their pros, cons, and outcomes helps you choose the right path.
Botox for TMJ
- Mechanism: Neuromodulator injections into masseter/temporalis muscles to reduce hyperactivity.
- Pros:
- Fast relief (3–7 days)
- Minimal downtime
- Lasts 3–4 months per session
- Cons:
- Requires repeat treatments
- Out-of-pocket cost per unit
- Outcomes: High patient satisfaction (>80% report significant pain reduction)
- Ideal Candidate: Chronic bruxers/clenchers who haven’t responded to splints.
Occlusal Splints & Night Guards
- Mechanism: Custom-fitted acrylic device worn at night to redistribute bite force and protect teeth.
- Pros:
- Protects enamel from grinding
- No injections required
- One-time fabrication (replacements 6–24+ months)
- Cons:
- Takes adaptation (gag reflex, speech)
- Only passive protection—no active muscle relaxation
- Outcomes: 50–70% report reduced pain, but many combine with other therapies for best results
- Ideal Candidate: Mild-to-moderate grinders and first-line conservative therapy seekers.
