Is it required to get a root canal before having a tooth crowned?

No: If a back tooth has had a root canal, crowns are often recommended to keep the tooth from splitting in half. There are other reasons for placing crowns though so the rule doesn't hold both ways, i.e. Crowns are often placed with no need for a root canal afterwards.

No: Your dentist can tell you why you might need the root canal. Usualy if a tooth has had a root canal, the treatment is to crown the tooth.

Crown and rootcanal: The answer is no if there is no pain, infection, or decay present. A crown protects a vulnerable tooth from fracturing beyond repair. A back tooth that had a rootcanal usually needs a crown. Not the reverse.

Hope this helps:: While most teeth that have had root canal therapy usually require a crown, most teeth that require crowns do not need rct. Rct is necessary when the nerve of the tooth is irreversibly damaged or occasionally as an elective procedure for a number of special circumstances. If there is enough tooth structure left to support a crown, and the “nerve” is fine, rct is not required.
