What is Teeth Grinding?

Teeth grinding or Bruxism is a condition where patients grind or clench their teeth, wearing down tooth enamel and causing dental problems. This often happens when sleeping, but is also an unconscious habit when awake. Many people don’t know they grind their teeth until their dentist diagnoses them with significant teeth wearing.

Why does it happen?

The cause can be anxiety or stress or built-up tension which can cause teeth to clench up, or even deep concentration.
Physical reasons include an abnormal or uneven bite, bad tooth alignment, missing or crooked teeth. Uneven dental fillings can contribute, as can Sleep Apnoea where grinding is a natural reflex to unblock the airway.

Why is it harmful?

Bruxism can cause headaches, earaches, jaw pain and toothache. Facial structure and profiles can also change as grinding impacts the jaw and surrounding muscles. Severe grinding can lead to jaw dysfunction, such as temporomandibular disorders (TMD), which causes pain and compromised movement of the jaws and surrounding muscles.
Chronic teeth grinding results in excessive wear, chipping, fractures, loosening or loss of teeth. Grinding can also loosen and damage existing fillings, decreasing the longevity of the filling. Continuous grinding can weaken the surface of the teeth and increase sensitivity to hot and cold.
