Bruxism and Teeth-clenching

Updated: Aug 10


Do you suffer from teeth-grinding?

What is bruxism?

Bruxism is more commonly known as 'teeth-grinding'. It is a habit which affects approximately one in ten people of all ages. Most teeth-grinding happens during sleep and can range from mild to severe. Sometimes it is only short-term, and thus relatively harmless. However, persistent teeth grinding, especially at night, can cause serious dental and jaw joint damage. It can also cause headaches, jaw muscle pain, and other health problems.

  • sleep disorders including obstructive sleep apnoea

  • medications such as antipsychotics and antidepressants

  • excessive alcohol consumption, tobacco use and gum chewing

  • recreational drug use

  • medical conditions such as Parkinson’s Disease and Huntington’s Disease

It is important to understand the cause of your bruxism to get effective treatment.

Symptoms of bruxism

The most common time people grind their teeth is during sleep, so you may not notice it yourself. In fact, other people may notice it before you do. However, here are a few common symptoms:

  • Aches/pains in your teeth, jaws, ears, head and/or face when you wake up

  • Stiff shoulders, tight jaw muscles, enlarged jaw muscles

  • Difficulty opening your mouth wide when eating or speaking

  • Cracking or popping when your jaw moves

  • Worn down teeth, abnormal tooth wear, loose teeth, teeth fractures

  • Damage to fillings and other dental restorations

  • Straightening of teeth

  • Jaw alignment

  • Prosthodontic treatments such as crowns and/or veneers

  • Relaxation exercises

  • Lifestyle changes such as giving up smoking
