Bruxism is grinding, gnashing or clenching of the teeth. It is usually involuntary and can occur nocturnally or when the sufferer is awake. People who grind their teeth, particularly at night, may not be aware they are doing it. A partner may hear the  grinding noise, leading the sufferer to seek a diagnosis, or signs of wear and tear that may be spotted by a dentist during a checkup.

Diagnosing bruxism can be likened to a catch 22 situation. Early diagnosis of bruxism and appropriate treatment can prevent long term damage to the teeth. Unfortunately the symptoms needed to arrive at such a diagnosis will often mean the damage is already well underway.

Unaddressed, bruxism can lead to permanent damage to tooth enamel and even teeth cracking and being lost altogether. Pain caused by bruxism can become chronic, and detrimental to quality of life and wellbeing. The possible effect on sleep quality is also a concern – problems associated with sleep deprivation are well documented and can negatively impact on family and work life. If you suspect that you or a family member is suffering from bruxism, then read on for more information on symptoms and guidance on how to proceed.


The signs and symptoms of bruxism can include the following:

  • Wear and damage to teeth and fillings
  • Tooth sensitivity
  • Headache/earache
  • Jaw pain and stiffness – this will be most noticeable in the morning for sleep ‘bruxers’
  • Clicking of the temporomandibular joint
  • Indentations in the teeth and tongue
  • Poor quality sleep for the sufferer and/or partner
  • Growth of bony protuberances known as torus mandibularus
  • In childhood bruxism, sleep disruption can manifest as behavioural problems


It’s believed that a large proportion of the population will ‘brux’ at some time during their life. A figure of approximately five percent will do it often and consistently enough to be clinically diagnosed with bruxism.

The nocturnal variety of the condition is more prevalent in males, whereas females are more likely to be afflicted with awake bruxism.

Bruxism is also common in childhood. Wear and tear on the teeth is more noticeable in milk teeth because the enamel is thinner, however most children will just grow out of it without any long term impacts. If the problem is more serious then it is wise to seek help, especially if there are any other symptoms relating to other sleep disorders such as sleep apnoea.


It was once thought that bruxism was caused by teeth misalignment, but this has now been ruled out.

The causes of teeth grinding may not always be clear, but it is thought that stress is a contributing factor. The link with stress may be more obvious in the case of awake bruxism. In nocturnal bruxism, links have been identified with anxiety, smoking, alcohol use,  and other sleep disorders such as sleep apnoea. It has also been noted that certain antidepressant medications can cause bruxism.

Some research suggests that certain people may be genetically predisposed to develop bruxism, with a significant number of sufferers having a family member who had suffered from the condition as a juvenile.
