Why do I need root canal treatment?

Root canal treatment is only required when dental X-rays show that the pulp has been damaged by a bacterial infection. There are many clinical reasons for needing root canal treatment, but there are also countless practical reasons why saving the natural tooth is a wise choice. Endodontic treatment helps you maintain your natural smile, continue eating the foods you love and limits the need for ongoing dental work. With proper care, most teeth that have had root canal treatment can last a lifetime.
