What are the signs that I should visit a root canal specialist instead of waiting for the tooth pain to settle?

In my experience, patients often wait because they think tooth pain or sensitivity will disappear on its own. Persistent pain, sensitivity to hot or cold, pain when biting, swelling, or a recurring dental problem can indicate an issue inside the tooth. A root canal specialist can assess the tooth carefully and determine whether endodontic treatment is needed. Early assessment may help protect the natural tooth and prevent the problem from becoming more complicated.
