A painless root canal treatment, also known simply as a root canal, is a dental procedure used to treat infected or damaged tooth pulp. The procedure involves removing the infected or damaged pulp from the inside of the tooth, cleaning and disinfecting the area, and then filling and sealing it to prevent further infection. The term "painless" is often used to describe this procedure because dentists typically use local anesthesia to numb the area around the tooth, ensuring that the patient doesn't feel any pain during the treatment. Additionally, advancements in dental technology and techniques have made root canals more comfortable for patients, further reducing any potential discomfort during the procedure. Overall, a painless root canal aims to effectively treat the tooth while minimizing any discomfort or pain experienced by the patient.
