Root Canals are recommended or needed when an untreated cavity has caused deep decay in the centre of the tooth or there is an infection deep within the tooth. Deep cavities close to the centre of the tooth may not display symptoms immediately, however, they can be diagnosed using x-rays. Infection symptoms, when they appear, can range from mild to severe discomfort and may become more intense the longer you live with the discomfort. You may feel pain after eating hot or cold foods, which could linger for 30 seconds or more. The pain may feel like constant throbbing or pressure on your tooth, in which case eating and chewing might aggravate the tooth even more. A dental visit is necessary to treat this kind of tooth pain.
