Teeth grinding, or bruxism, is clenching or grinding your teeth, usually during sleep. It is often linked to stress, sleep problems and certain habits. Many people do not know they grind until a partner hears it or a dentist sees the wear. The most effective way to protect your teeth is a custom-made night guard, combined with tackling the underlying causes.
Signs you may be grinding your teeth
- Waking with a sore jaw, headache or earache
- Flat, worn or chipped teeth
- Increased tooth sensitivity
- Tired or tight jaw muscles
- Cracked teeth or broken fillings
- Indentations on your tongue
- A partner hearing grinding at night
What causes teeth grinding?
- Stress and anxiety, the most common trigger
- Sleep disorders, especially sleep apnoea and snoring
- Caffeine, alcohol and smoking
- Some medicines, including certain antidepressants
- Bite problems or missing teeth
- Concentration habits, such as clenching while working
Why grinding matters
Grinding puts heavy forces on your teeth for hours at a time. Over months and years this can wear teeth down, crack them, damage crowns and fillings, and strain the jaw joint.
How to stop grinding your teeth
- Wear a custom night guard. It cushions your teeth and spreads the force. Shop-bought guards fit poorly and can sometimes make clenching worse.
- Manage stress with exercise, relaxation or talking therapies.
- Cut back on caffeine and alcohol, especially in the evening.
- Notice daytime clenching and keep your teeth apart, jaw relaxed.
- Get checked for sleep apnoea if you snore or wake tired.
- Repair worn teeth to restore a balanced bite.
- Botox decreases muscles activity.
Teeth grinding in children
Grinding is common in young children and often stops as adult teeth come in. Mention it at their check-up so we can monitor wear.
