A root canal is a dental procedure used to treat an infection in the center of the tooth, also known as the pulp. According to Dr. Kamila, the procedure involves removing the infected or damaged pulp, thoroughly cleaning the canal, and sealing it to prevent future infections. It’s typically recommended when a tooth has severe decay, an abscess, or deep-rooted infection. Root canal treatment may also be necessary if you experience persistent pain or sensitivity that doesn’t go away.
