A BEAUTIFUL SMILE WITH
A crown is a full tooth covering made of metal and/or ceramic that helps protect the tooth from breaking more or wearing down. Generally a tooth that has had a root canal is weaker because it is hallow and dead. Protecting a root canal treated tooth with a crown will help it last longer. This is especially the case with the back teeth that are bigger and do a lot of grinding to crush food.
Crowns can also help cover front teeth that have large fillings that continue to break. Front teeth that have had root canals tend to turn dark gray or black over time. A crown will mask or cover up the teeth that are dead and look darker.
