What You Need To Know...

A root canal, also known as root canal therapy and endodontic therapy, is a procedure that is done by a dental professional to salvage a damaged or infected tooth without the need for extraction. Root canal therapy becomes necessary when the dental pulp in the center of the tooth becomes infected from a neglected area of tooth decay. Prevention is key. This includes regular examinations, cleanings, and x-rays to catch a problem early on. Trauma to the tooth may also require a root canal due to the damage caused to the nerves. The dental pulp becomes infected and can form an abscesses which affects the surrounding bone of the jaw. An abscess cannot heal on its own and can weaken one’s immune system. Patients with an infected dental pulp may notice sensitivity to extreme temperatures, pain with pressure, swelling of the gums, and/or a strange taste in the mouth. Other times, patients may not experience any symptoms and the problem can only be found with an evaluation.

During root canal therapy, the dental pulp that is infected is removed and the canals of the tooth are disinfected. The canals are then filled to keep bacteria from entering into the tooth structure again in the future. Crowns are often fabricated to bond over the natural tooth to keep it strong and durable. The only other alternative to a root canal is the permanent extraction of the tooth along with replacement with bridges, dentures, or dental implants.
