When a tooth develops a crack or deep cavity, it can allow bacteria to enter the pulp tissue, leading to an infection inside the tooth. This can result in inflammation of the tooth nerve or an abscess, often causing pain and swelling. If left untreated, the infection can lead to tooth loss, damage to the jaw bone, and even pose a risk to your overall health as it can spread into your bloodstream, potentially reaching your heart and brain.

While teeth in need of root canal therapy may not always be painful, symptoms such as severe toothache, pain when biting or chewing, sensitivity to hot and cold temperatures, tooth discoloration, or gum swelling and tenderness could indicate the need for a root canal.

Root canal therapy is performed to save a tooth's structure when the nerve inside is damaged to the point where extraction is the only other option. The procedure involves cleaning out decay, removing the damaged nerve, and filling and sealing the tooth's inner chamber with dental composite to preserve the outer structure.

Root canals are typically done in one office visit and, with proper care like regular brushing, flossing, and checkups, a restored tooth can last a lifetime. In cases of extensive decay, a crown may be necessary to strengthen the tooth and prevent further damage. Ultimately, getting a root canal when needed can save your tooth and maintain your smile.
