Root canal treatment is necessary when the pulp, the soft tissue inside the root canal, becomes inflamed or infected. There are a whole host of reasons why you might need root canal treatment:
In addition, an injury to a tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess.
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.
