Is it necessary to get a dental crown after root canal treatment?

Whether a dental crown is necessary after root canal treatment depends on the individual patient's condition. Generally, teeth that have undergone root canal treatment lose support from the pulp and blood vessels, making them more brittle and prone to cracking. To protect the tooth and extend its lifespan, a dental crown is usually recommended. Specifically, if the treated tooth is a lower front tooth or a premolar, where chewing forces are relatively low, a crown may not be necessary. However, for molars or upper front teeth, which endure greater chewing forces, a crown is typically required for protection. After receiving a dental crown, patients should observe the following: avoid biting hard objects to prevent crown fracture; maintain good oral hygiene by brushing and rinsing regularly to prevent tooth decay; and schedule routine dental check-ups to detect and address any issues early.
