After reducing the cause of the stress, the primary prevention and treatment is a bite guard. This is made of plastic and customized to fit your bite. It reminds you not to grind your teeth and protects you when you do. The tooth structure which is lost can be quite excessive as in this case. You can see that most of the enamel has been worn away exposing on the second layer called dentin which is yellow and not very pretty. Even worse, dentin is very soft and is extremely vulnerable to cavities and wear.
I decided to restore this case using porcelain fused to metal crowns.
