Tooth sensitivity can occur when tooth enamel has been worn down, and the dentin or the even the nerves of teeth are exposed. When these surfaces are exposed, eating or drinking something with an extremely low or high temperature may cause you to feel a sudden, sharp flash of pain.

Can tooth sensitivity come and go?

What causes sensitivity? Tooth sensitivity can come and go with time and is usually caused by exposed dentin on root areas from gum disease and/or receded gums. Unlike the crowns of your teeth, the root area of your tooth isn't protected by enamel, but rather cementum.
