If a tooth infection spreads through the pulp and then into the roots, there are serious consequences. Pain and sensitivity are the first signs, and if left untreated, it could lead to an abscess.
Root canals are tiny passageways that branch off from beneath the top of the tooth, coursing their way vertically downward, until they reach the tip of the root. Root canal therapy involves removing the diseased tissue, aiming to stop the infection and restore the healthy portion of the tooth. In fact, root canal therapy is designed to save a problem tooth.
