In 30 seconds: Bruxism (teeth grinding) is treated stepwise. Step 1: a custom hard night guard worn during sleep — it protects the teeth but does not stop the clenching itself. Step 2: physiotherapy and jaw exercises — useful for daytime tension. Step 3: masseter botulinum toxin — the only treatment that breaks the involuntary muscle-contraction cycle, with 80 to 90% improvement in symptoms.
Are you a “bruxist”?
You probably are if:
- You wake up with sore jaw, temples or shoulders.
- Your partner tells you that you grind your teeth at night.
- Your teeth have worn flat, chipped, or fractured.
- You have unexplained tension headaches in the morning.
- Your masseters look prominent (square lower face).
- You have ear pain or tinnitus without an ear cause.
Bruxism affects roughly 1 adult in 5. It is often linked to stress, anxiety, sleep disorders (notably sleep apnoea), and certain medications (SSRIs in particular). It can occur during sleep (sleep bruxism) or during the day (awake bruxism) — the two require different treatment strategies.
Why night guards alone are rarely enough
A custom-made hard acrylic night guard:
- ✅ Protects your teeth from wear and fracture.
- ✅ Reduces the load on the temporomandibular joint.
- ❌ Does NOT reduce the underlying muscle contraction.
- ❌ Many patients clench AGAINST the guard, ending up with more masseter pain.
The night guard is essential — but it treats the consequence (tooth damage), not the cause (muscle contraction).
Avoid soft guards from the pharmacy. They can paradoxically increase clenching because the brain interprets the soft material as something to chew.
Physiotherapy: useful but partial
Jaw and orofacial physiotherapy typically includes:
- Stretching and relaxation exercises for the masseter and temporalis
- Trigger point release on the masseter and temporalis
- Postural retraining (the cervical spine is frequently involved)
- Diaphragmatic breathing and stress regulation
Best for: daytime jaw clenching, muscle tightness, posture-driven TMJ pain.
Limits: physiotherapy does not control sleep bruxism alone, because the contraction is involuntary and occurs while you sleep.
Masseter Botox: the only treatment that breaks the cycle
When 30 to 40 units of botulinum toxin type A are injected into each masseter:
- Muscle contraction strength drops by 50 to 70% for 4 to 6 months
- The clenching cycle physically cannot occur with the same intensity
- Headaches resolve in 80 to 90% of patients within 4 weeks
- Teeth wear stops at the source
- Sleep quality often improves
The session takes about 10 minutes. No downtime. The slimming of the lower face is a frequent welcome side-effect.
Comparison table
| Treatment | Stops grinding? | Protects teeth? | Reduces headaches? | Best for |
|---|---|---|---|---|
| Night guard alone | ❌ | ✅ | Partial | Mild bruxism, dental protection only |
| Physiotherapy | Partial (daytime) | ❌ | Partial | Daytime clenching, postural component |
| Masseter Botox | ✅ | Indirect | ✅ | Sleep bruxism, headaches, jaw slimming |
| Combined approach | ✅ | ✅ | ✅ | Most patients (recommended) |
The stepwise approach used at the practice
- Clinical exam + TMJ palpation to confirm muscular bruxism versus joint disorder.
- Custom hard night guard prescribed and fitted with a partnered dental lab.
- Physiotherapy referral if there is a daytime clenching or postural component.
- If symptoms persist after 6 weeks: masseter Botox.
- Maintenance: Botox every 4 to 6 months, plus lifestyle adjustments (stress management, sleep hygiene, screening for sleep apnoea when relevant).
This combined approach achieves > 90% symptom control in our patients.
Frequently asked questions
Q: Is bruxism curable?
A: Managed rather than cured. With the combined approach (night guard + masseter Botox), most patients achieve full symptom control for as long as they maintain treatment.
Q: Can stress management alone cure bruxism?
A: It helps, but rarely sufficient on its own. The neuromuscular pattern persists even when stress reduces.
Q: How long does Botox last for bruxism?
A: 4 to 6 months on average. With repeated treatments, the muscle progressively atrophies and intervals can lengthen.
Q: Will my jaw look weaker with bruxism Botox?
A: The lower face slims, which is often a wanted side effect (V-shape). Chewing strength remains adequate.
Q: Should I see a maxillofacial surgeon or a dentist for bruxism?
A: Both. The dentist makes the night guard and assesses dental wear. The maxillofacial surgeon (or specialist physician) treats the underlying muscular and joint components.
Q: Does sleep apnoea cause bruxism?
A: There is a strong correlation. Up to 50% of bruxists also have a degree of obstructive sleep apnoea. A sleep study is worth considering if you snore heavily or feel unrested in the morning.
