Teeth Grinding
Bruxism is the medical term for teeth grinding or jaw clenching. While occasional grinding may not cause harm, regular or severe bruxism can lead to discomfort, jaw pain, worn-down teeth, and even headaches or earaches.
Most cases — nearly 80% — happen during sleep and are often linked to stress or anxiety. In fact, around 70% of sleep-related bruxism is believed to be stress-induced. People may also clench their jaws while awake, especially when they’re concentrating or feeling tense, though this is more likely to involve clenching rather than grinding.
Even though many people aren’t aware they’re doing it, persistent bruxism can have a real impact on dental and overall health. If you’re experiencing symptoms, our team can help assess the issue and advise on suitable treatment options.
Bruxism is often linked to multiple factors. There’s a strong connection between teeth grinding and obstructive sleep apnoea (OSA) — a sleep disorder where breathing repeatedly stops and starts during the night. Certain antidepressants can also trigger teeth grinding, and lifestyle choices play a role too. Regular alcohol consumption, smoking, and the use of recreational drugs like ecstasy or cocaine can all increase your risk.
Doctors sometimes refer to “primary bruxism” when teeth grinding isn’t linked to any other condition, and “secondary bruxism” when it’s associated with medications, medical conditions, or lifestyle factors.
Treating Bruxism
There are several ways to manage bruxism, but only a few treatments have been shown to be particularly effective. These include:
- Behavioural therapies, such as stress management and habit-reversal techniques
- Mouth guards or splints, which cushion the teeth and help prevent wear and tear
- Mandibular advancement devices (MADs), especially for those with sleep-related bruxism
- Muscle relaxation exercises and good sleep hygiene can also help reduce symptoms
If you grind your teeth during sleep, wearing a custom-made mouth guard, splint, or MAD at night can help protect your teeth and relieve pressure on your jaw.
