Grinding: What You Should Know

1 Mar

 

Bruxism is the involuntary clenching, grinding and gnashing of the teeth. About half of the population does it from time to time. Around five per cent of the population are regular, forceful tooth grinders. Often it happens during sleep, but some people grind their teeth when they are awake.

Usually, a person doesn’t realise that they grind their teeth in their sleep. The partner who shares their bed (and hears the grinding noises at night) is often the first to notice the problem. Parents may also hear it in their sleeping children.

Teeth grinding can be a result of stress. For example, some people grind their teeth when they are angry, concentrating or feeling anxious.

Effects of teeth grinding

-broken teeth or broken restorations (for example, fillings)
-strain on the jaw joint (temporo-mandibular joint)
-pain in the jaw joint or limited movement
-sore jaw muscles
-tooth loss (rare)
-enlargement of the jaw muscles (rare).

Causes of teeth grinding

Some of the many factors believed to trigger teeth grinding include:
-emotional stress, such as anger or anxiety
-mental concentration
-physical stress, such as illness, poor nutrition or long-term pain
-some dental treatments, such as fillings that sit ‘too high’
-drug use (particularly amphetamines)
-when teeth are coming through in babies and children.

Treatment for teeth grinding

If you think you grind your teeth, see your dentist or other oral health professional as soon as possible. They will look at your teeth and talk about possible treatment options that may include:
-repair of tooth damage
-fixing fillings that are too high
-a special mouthguard (‘bite splints’) to wear at night so that the guard is worn down instead of your teeth. In most cases, a bite splint will only help with the symptoms and will not stop you from grinding altogether.
Other treatments that may help to manage teeth grinding include:
-stress management therapy
-relaxation techniques
-cognitive behaviour therapy
-regular exercise
-medication that relaxes the muscles.mouthguard
