Endodontics is a branch of dentistry that deals with the treatment of root canals in teeth.

Under the enamel and dentin layers of the tooth, there is a section called Pulp, where the vessels and nerves that provide the vitality of the tooth reside.

Inflammation occurs in this part of the tooth due to caries and trauma. Pain and swelling in the face may occur.

The general belief is that the tooth, which forms a swollen face, will be extracted after the swelling disapperars.

However, with the new technology, even teeth that cause major infection can be retained in mouth by root canal treatment and can be used healthily for many years.
