Tooth Grinding
Bruxism
- Grinding the teeth can cause wear.
- The canines and the front incisors wear first.
- The enamel can be lost exposing the soft dentine underneath.
TMJ
- When the jaw opens, there are two movements involved – a rotation and a sliding.
- Cartilage between the bones smoothes the movement.
- Sometimes as cartilage wears, it may click during the opening.
