Bruxism: treatment for chronic teeth grinding and clenching
Bruxism is habitual grinding and clenching — usually during sleep, often without the patient's awareness. At Unclench Dental, we evaluate whether therapeutic botulinum toxin can reduce the muscle intensity that drives the wear and the pain.
What bruxism actually is
Bruxism is not a single disease. It's a pattern of repetitive, involuntary clenching and grinding of the teeth driven by the masseter and temporalis muscles. Sleep bruxism happens unconsciously during sleep, often in the lighter stages. Awake bruxism happens during concentration, stress, or screen use — and many patients don't notice it until their jaw aches at 4 p.m.
The common thread is overactive muscle tone that the patient cannot consciously control. That's why behavioral approaches often stall: you can't will yourself to stop clenching at 3 a.m.
Signs you may be grinding or clenching
- —A partner who hears you grind at night
- —Nightguards that wear through or crack within months
- —Flattened, chipped, or fractured teeth
- —Morning jaw stiffness or soreness
- —Temple and jaw headaches on waking
- —Visibly enlarged masseter muscles
- —Linear scalloping along the sides of the tongue
- —Tooth sensitivity without decay
Nightguards do real work — and have a real limit
A well-fitted nightguard from your general dentist is essential — it protects enamel from the mechanical force of grinding, prevents fracture of restorations, and gives your dentist a way to monitor wear patterns. If you have one, keep wearing it. We don't replace it.
What a nightguard doesn't do is reduce the clenching itself. The force continues; the guard simply shields the teeth from it. So patients who have worn guards for years often report the same morning pain, the same headaches, and the same face ache by afternoon — because the muscle is still firing at the same intensity.
Therapeutic botox is the complementary piece. The guard protects the structure; the injection reduces the force. For patients whose bruxism is driven primarily by masseter/temporalis overuse — not occlusal instability or airway pathology — the two together can meaningfully reduce both symptoms and ongoing dental wear.
How botox changes the pattern
Injected into precise sites in the masseter and (when indicated) the temporalis, botulinum toxin temporarily reduces the force of contraction. Patients typically report:
- —Less morning soreness within 2–3 weeks
- —Fewer tension headaches
- —Softer facial appearance from reduced masseter bulk
- —Partners who no longer hear grinding at night
- —Nightguards that last longer

Frequently asked questions about bruxism
Bruxism is habitual grinding or clenching of the teeth, which can happen during sleep (sleep bruxism) or while awake (awake bruxism). It often occurs without the patient's awareness and can cause significant wear to teeth, restorations, and jaw muscles over time.
Botulinum toxin injected into the masseter and temporalis muscles temporarily reduces the intensity of contraction. In bruxism patients, this decreases the force of clenching and grinding, often reducing morning jaw soreness, headaches, and further dental wear.
Unclench Dental is a cash-pay practice. We do not bill insurance, file claims, or issue paperwork for insurance or HSA/FSA reimbursement. Pricing is transparent and disclosed before any treatment.
Sometimes. Botox reduces the force but does not always eliminate grinding entirely. Many patients continue to wear a nightguard for enamel protection while benefiting from reduced muscle activity from treatment.
Dosage varies by patient and muscle size. A typical range is 20–30 units per masseter and 10–20 units per temporalis, adjusted based on response over successive visits.
