Does a tooth with a root canal need a crown?

Some people might say that a root canal is very costly, and to have a crown on top is even more expensive! But in order to make sure a tooth treated with a root canal to sustain chewing forces and to last a long time without fracturing, it is important put a crown on it.

A dental crown serves to make a tooth more solid and maintain its integrity after it has suffered destruction, either from tooth decay or from a trauma. A tooth that must get a root canal probably already had a very large cavity that had reached the pulp chamber where the nerve is located. After the dentist had properly cleaned the tooth from all decay and that the root canal treatment is completed, there usually doesn’t remain sufficient healthy tooth material to restore the tooth with a filling. It is then necessary to complete the treatment by a post and a crown to ensure that the tooth will not break eventually.

There are however certain situations where a tooth’s nerve is irritated after a trauma and not because of a destructive dental cavity. If the tooth that had the trauma is not broken or cracked, and if it did not already have a big filling, then some dentists believe that it’s possible to do a root canal without a crown. In this case, a filling (with or without a post) is enough to restore such a tooth.
