Why would i need a crown after a root canal

Root canal treatment removes diseased pulp, cleans and seals the canals, and restores the access opening. A back tooth often receives strong chewing forces, so a cuspal-coverage crown can help protect the remaining walls from flexing and fracture.

The dentist removes decay, evaluates the remaining enamel and dentine, confirms the canals are sealed, and designs a restoration with enough ferrule and contact with neighbouring teeth. The tooth may receive a temporary restoration first, followed by preparation, an impression or scan, and a fitted crown.

Return promptly if the temporary filling loosens, the tooth cracks, swelling appears, or pain increases. Do not chew hard foods on a tooth that has not received its planned final restoration.

Ask how much tooth structure remains, whether cuspal coverage is needed, which material fits the tooth, and how the temporary restoration should be protected.
