Cracked teeth can be identified by several symptoms including pain when chewing, temperature sensitivity, or even the release of biting pressure. Cracked teeth can be difficult to diagnose due to the pain often coming and going.
Chewing can cause movement of the cracked pieces of your tooth, causing the pulp within the tooth to become irritated. This can also result in a sharp pain associated with the release of biting pressure. When biting pressure is released the cracks in the tooth tend to close quickly, causing a sharp pain. Eventually, the pulp will become damaged and the tooth will consistently hurt, even when you are not chewing. It is possible that cracks can lead to infection of the pulp tissue, which then can show itself as infection and inflammation in the surrounding gums and bone.
