Cracked teeth demonstrate many types of symptoms, including pain when chewing, temperature sensitivities, or the release of biting pressure. It is also common for pain to come and go, making it difficult to diagnose the cause of discomfort.
Chewing can cause movement of the cracked pieces of your tooth, and the pulp within the tooth becomes irritated. At the same time, when biting pressure is released, the crack can close quickly, resulting in sharp pain.
Cracks may or may not extend into the root. If the crack does not extend into the root, the tooth can usually be restored by your dentist with a full crown. If the crack does extend into the root and affects the pulp, root canal treatment is usually necessary in an attempt to save all or portion of your tooth.
