Root canal treatment (endodontics) is a dental procedure to remove inflamed or infected pulp on the inside of the tooth, which is then carefully cleaned and disinfected then filled and sealed.

According to Dr Benjamin Simiyu, an endodontist, the treatment is done to eliminate bacteria from the infected root canal, prevent reinfection of the tooth and save the natural tooth.
