What is teeth sensitivity?
Teeth discomfort normally arises when the dentin, the underlying layer of your teeth, gets exposed. Two main causes are the Erosion (wear and tear) and gum recession (when your gum tissue pushes away from your teeth, exposing the roots).
The teeth roots, which aren't coated by hard enamel, contain hundreds of microscopic tubules that lead to the interior of your tooth (the pulp). These dentinal tubules (or channels) allow stimuli — for example, hot, cold or sweet food — to reach the nerve in your tooth, which results in the pain you feel.
