what a cracked tooth feels like
Cracks on teeth are usually quite small. There are two types of cracks. One where the tooth actually is cracked which usually will be very painful, and the other which is an enamel line fracture, which might look like a crack but it doesn't hurt and is only on the level of the out layer of the tooth, the enamel. Rapid changes in temperature can cause small hair line fractures in the tooth.
