Teeth sensitivity can be painful, and it can impact daily activities, such as eating, drinking, brushing teeth, or even breathing cold air. Teeth sensitivity can be triggered by hot or cold food and drinks. Some people describe the pain to be sharp, sudden, and shooting deep into the nerve endings of their teeth.
Studies have shown that over 40 million Americans have teeth sensitivity.
What are the causes?
What are the treatments?
Understanding the anatomy of the tooth may help to answer some of the questions. There are four major tissues that make up the tooth. They are: enamel, dentin, cementum, and dental pulp (nerves).
-Enamel is the most outer layer of the tooth. It is the part of the tooth you see when you open your mouth, talk and smile.
-Dentin is the layer of tissues underneath the enamel and cementum. Dentin contains a large number of pores or tubes called dentinal tubules. When they are exposed to the outside stimuli, such as the hot or cold food and drinks, they stimulate the nerve of the tooth and cause teeth sensitivity.
-Cementum is the layer of tissues that cover the root of the tooth
-Dental pulp is the center of the tooth that is filled with blood vessels and nerves.
