The Endodontic Experts
Endodontic treatment treats the inside of the tooth. Endodontic treatment is necessary when the pulp becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, faulty crowns, or a crack or chip in the tooth.
With proper care, even teeth that have had root canal treatment can last a lifetime. But sometimes, a tooth that has been treated doesn’t heal properly and can become painful or diseased months or even years after treatment. If your tooth failed to heal or develops new problems, you have a second chance. An additional procedure may be able to support healing and save your tooth.
Occasionally, a nonsurgical root canal procedure alone cannot save your tooth and your endodontist will recommend surgery. Endodontic surgery can be used to locate small fractures or hidden canals that weren’t detected on x-rays or during previous treatment. Surgery may also be needed to remove calcium deposits in root canals, or to treat damaged root surfaces or the surrounding bone of the tooth.
Cracked teeth demonstrate many types of symptoms, including pain when chewing, temperature sensitivities, or even the release of biting pressure. Chewing can cause movement of the cracked pieces of your tooth, and the pulp within the tooth becomes irritated. At the same time, when biting pressure is released, the crack can close quickly, resulting in sharp pain.
Traumatic dental injuries often occur in accidents or sports-related injuries. Chipped teeth account for the majority of all dental injuries. Dislodged or knocked-out teeth are examples of less frequent, but more severe injuries. Treatment depends on the type, location and severity of each injury. Any dental injury, even if apparently mild, requires examination by a dentist or an endodontist immediately.
