Root canal treatment, also known as endodontics, is a dental procedure designed to treat infection or decay that has occurred at the centre of the tooth. Root canal treatment is designed to save the tooth and prevent the spread of infection. The damaged pulp is removed from the tooth and the root canal is then cleaned of all bacteria. After the bacteria has been removed, the root canal and pulp are filled in using an artificial substance, before being sealed.
Historically, lack of knowledge in local anaesthetics together with old techniques, materials and equipment made this procedure painful and often unsuccessful. However by mastering the art of local anaesthetic combined with sophisticated equipment the procedure can become pain-free, more successful and much easier to tolerate.
