I will have a root canal. Is it necessary to put crown after a root canal?

In most cases it is advised because most teeth requiring root canals have had a tough life with a lot of tooth structure loss and weakened walls. In addition a root canal does hollow out the inner aspect of the tooth further weakening it but that is a necessary downside of the procedure. A crown is placed over the remaining tooth structure like a "cap on a fencepost" to support tooth structure externally.

Hi,

Thanks for your question. Most of the time it is. The reason is that teeth that need root canals have usually been through a lot. Fillings, decay, breakage, All of these things weaken the tooth. Usually these teeth need support and only a crown will give that. The exception is a front tooth with no damage but has had a trauma like getting knocked very hard. Sometimes those don’t require support because they are intact.

Hope this helps,

After a root canal treatment (rct) the tooth tends to get brittle in the long run. If the opening access for rct is small, there may not be any need for a crown. Large defects due to decay will need a crown to maintain the integrity of the tooth.

Usually, it is. It depends on the circumstances. You can discuss it further with your dentist. The crown/cap protects the tooth so it doesn’t fracture and you don’t have to extract it.

It is usually necessary to have a crown after root canal because teeth that usually require root canals have existing large fillings and cannot be filled again. However, this is just a generalization. Teeth should be evaluated on a case by case basis to determine what is needed.

On a molar or premolar tooth, it is usually recommended to place a crown after a root canal. On the anterior teeth, sometimes it is optional.
