Why Do People Need Root Canals?
You might need root canal treatment if an infection develops in the nerve and blood chamber within the core of your tooth. This portion of the tooth is called the dental pulp. According to the American Dental Association, there are times when this space can get infected from a deep cavity (tooth decay), a cracked tooth or as a result of periodontal disease. When bacteria infect the area, the dental pulp may die, causing pus to build up at the tip of the tooth root. This infection is called a periapical abscess.
If your dentist confirms that the abscess is a result of dental decay or a cracked tooth, they will often recommend a root canal treatment as the best course of action. This procedure removes the bacteria from within the tooth and seals it to stop the infection.
Know that your dental professional will do everything in their power to treat the problem and save the tooth rather than extract it. The American Association of Endodontists (AAE) reports that more than 15 million root canals are completed in the U.S. annually to preserve natural teeth by cleaning out the infection and stabilizing the treated tooth with the proper filling materials.
