Root canal therapy is necessary when infection has built up inside the nerves of the tooth. This could usually be caused by tooth decay, trauma or fracture. The procedure involves removing the inflamed or infected nerves or pulp, carefully cleaning and shaping the inside of the canal, and creating a channel inside the root. After removing the infection, the tooth is sealed with a protective and reliable filling material. Thus relieving pain and  preventing tooth extraction.

With modern technology and techniques, a root canal treatment is a relatively straightforward, quick and comfortable procedure.
