4 Things That Could Be Causing Your Tooth Sensitivity Problem
Tooth sensitivity is caused by nerve irritation after your protective enamel coat has been worn down by various causes. Your dentin (the layer under the enamel) contains tiny tubules that lead up to nerve endings. Exposing these tubules makes you more prone to irritate your nerves underneath. If you feel pain when your teeth are exposed to very hot or cold foods or air or acidic foods, you may have tooth sensitivity.
