Large fillings or extensive tooth decay can severely weaken a tooth. A tooth that has had a root canal treatment may also be weaker especially if it has a large filling. Teeth may also wear down over time or break due to a trauma such as a blow to the mouth.
Crowns are made of gold or porcelain and are extremely strong. They are fitted over an existing tooth and have the potential to extend the life of a tooth significantly. Crowns can also provide a very natural appearance to broken down or discoloured teeth.
