Pediatric dentist in Kovilambakkam What is pulpotomy? Pulpotomy also known as a baby root canal, is an endodontic treatment for tooth decay that has reached the dental pulp of the tooth. The dental pulp is the soft inner layer of the tooth that contains nerves, blood vessels, and connective tissue. Dental pulp can be damaged or infected as a result of dental trauma or untreated tooth decay, resulting in severe tooth pain. When decay has not yet reached the tooth’s root, a pulpotomy is a minimally invasive procedure used on baby teeth. It means infected/inflamed dental pulp from the crown while leaving the root intact. This differs from a root canal, which removes all of the dental pulp, right down to the roots. In either case, a medicated dressing is applied to the pulp at the root, and the vulnerable tooth is protected with a stainless steel crown.
