Root canal therapy, often simply referred to as a root canal, is a common dental procedure that can save your natural tooth and prevent the need for dental implants or bridges. At the center of your tooth is pulp, a collection of blood vessels that helps to build the surrounding tooth. Infection of the pulp can be caused by trauma to the tooth, deep decay, cracks and chips, or repeated dental procedures. Symptoms of the infection can be identified as visible injury or swelling of the tooth, sensitivity to temperature, or pain in the tooth and gums. If you experience any of these symptoms, your Gold Coast, Chicago dentist may recommend a root canal to eliminate the diseased pulp.
