Normally, the underlying dentin of the tooth (the layer that immediately surrounds the nerve) is covered by enamel in your toothâ€™s crown, and the gums that surround the tooth. This enamel covering may wear down over time, becoming thinner and providing less protection. Your gums can also recede over time, exposing the underlying root surface dentin. The dentin contains a large numbers of pores or tubes that run from the outside of the tooth to the nerve in the center. When the dentin is exposed, these tubes can be stimulated by changes in temperature or certain foods. Continue reading
