01 What it means

What does an endodontist do?

Root canal treatment removes the infected pulp, cleans and shapes the inside of the tooth, then fills and seals it so that it does not become infected again. The NHS says a dentist carries it out, and that you may also see a dentist known as an endodontist, who focuses on this work.1

Treatment usually takes two or more visits, each of an hour or two, and a temporary filling may be placed between them.1 Afterwards the tooth is usually restored with a filling or a crown, and the area can feel swollen and sore for a couple of weeks.1
