Lingering tooth sensitivity after eating or drinking something hot or cold? Sharp pain when biting or chewing? A toothache is almost always a sign that infection has damaged the pulp within your tooth root. This can be the result of a severe tooth crack or fracture, injury to a tooth, or extensive tooth decay that has reached the inside of the tooth. Without treatment, the infection will continue to cause tooth pain, can lead to a tooth abscess, and in worst cases will require the tooth to be extracted altogether. If you’re experiencing any noticeable symptoms, especially a severe toothache, we have a solution!
