Bruxism

Bruxism (Teeth Grinding)

Bruxism is characterised by excessive clenching or grinding of the teeth, and typically includes clenching of the jaw. It can lead to wear on the teeth may cause permanent damage to both the teeth and the jaw joints. What is clenching and grinding?

  • Clenching is when a person tightly clamps their upper and lower teeth together, especially the back teeth.
  • Grinding occurs when a person grinds their bottom jaw either back and forward, or sideways across their upper jaw.

These are both forms of Bruxism and these activities can occur during the day or at night. When a person is sleeping there is no conscious control over excessive clenching and grinding and this makes it a difficult activity to prevent. The causes of bruxism are still being studied; many of them are a combination of both physical and psychological factors which may include:

  • Psychological stress, anxiety and tension
  • Physical stress, illness, nutritional deficiencies
  • Abnormal anatomy of the teeth or jaws

Common signs and symptoms of Bruxism include:

  • Chronic facial pain and tension headaches
  • Broken or chipped teeth
  • Pain and sensitivity to heat and cold
  • Flattened, worn surfaces of the teeth which may reveal underlying yellow dentine
  • Stiffness/Pain in the jaw joint muscles, sometimes restricting opening and chewing
  • Loose teeth
  • A 'grinding' noise which may be noticed by friends, family or partners

Your Dentist will be able to accurately diagnose Bruxism and will prescribe a corrective treatment based on clinical examination and your medical and dental history.

Counselling, stress management or relaxation methods may also be recommended in conjunction with dental treatment. It is imperative to identify and address the issues triggering Bruxism. Treating Bruxism will involve removing the issues creating the problem, which may require behavioural changes as well as dental treatment.

An occlusal Splint is an option which not only relaxes the jaw muscles, but also stops further damage to the teeth, as the splint is worn away rather than tooth surface.Splints are worn at night and are made from moulded plastic that fits over the upper and lower teeth. We custom make the splint to perfectly fit each individual mouth, providing a comfortable and secure fitting. Dental fillings, crowns, or inlays can replace damaged tooth surfaces. In more severe cases, Root Canal treatment may be required where tooth fractures extend into the pulp.
