During a root canal treatment, the dentist or endodontist removes the infected or damaged pulp from inside the tooth. The tooth is then cleaned, disinfected, and shaped to prepare it for filling. After the root canal space is thoroughly cleaned, it is filled with a biocompatible material, typically gutta-percha, to seal the canals and prevent further infection.

Following the root canal procedure, the tooth is usually restored with a dental filling or crown to protect it and restore its function and appearance. Root canal treatment helps to alleviate tooth pain, resolve infection, and preserve the natural tooth structure, allowing the tooth to remain in the mouth and function normally.

Root canal treatment is typically performed under local anesthesia, ensuring that the procedure is comfortable and pain-free for the patient. With proper care and maintenance, a tooth that has undergone root canal treatment can last a lifetime, providing many years of healthy and functional use.
