Does root canal treatment require tooth extraction?

Root canal treatment generally does not require tooth extraction. It is a common dental procedure primarily used to treat pulp diseases and periapical lesions. By professionally cleaning, shaping, disinfecting the root canal, and then sealing it tightly, the goal of controlling infection can be achieved. However, in special circumstances—such as persistent pain after root canal treatment, the development of a gingival fistula, or when the tooth becomes too fragile due to lack of nutritional support—extraction may be necessary. It is recommended to take protective measures after root canal treatment, such as placing a ceramic crown, to protect the tooth.
