Your teeth contain several layers. The outer-most layer is the enamel, which helps protect your teeth against wear and tear and prevents bacteria infiltration. The next layer is the dentin. Beneath the dentin lies the pulp. When the enamel starts to wear away, the dentin can be exposed, which may lead to tooth sensitivity and cavities. Dentin becomes exposed if your enamel thins. This can be due to frequent acid-attacks by eating too many sugary foods and drinks too often and not brushing and flossing your teeth every day.
Dentin exposure can also occur due to a thinning of the enamel as we age. In fact, when the enamel starts to thin, it can cause the dentin to be viewable through the enamel, and since dentin tends to appear yellow, you may notice that your teeth are not a white as they were when you were younger.
Dental pulp contains the nerve fiber that interprets everything as pain.

Exposed dentin treatments your dentist might suggest include those noted by the American Dental Association ADA : Desensitizing toothpaste : Ask your dentist what toothpaste best blocks tooth nerve sensitivity.
You might have to brush over several days before you notice a sensitivity reduction. Fluoride gel : Your dental professional will administer this gel, which does double duty: It strengthens your tooth enamel and reduces teeth sensitivity. Dental crowns, inlays, or bonding : Your dentist might perform one of these procedures if your sensitivity results from decay or a dental imperfection.
