What is sensitive mouth?

Sensitive mouth is when more than 4-5 teeth suddenly feel sensitive on eating anything hot or cold or sweet. Sensitive mouth is when your teeth look flat and worn off with some surface irregularities and micro pores on your teeth.

Majority of your teeth may be worn off either due to repeated friction between your teeth, erosion or due to aggressive brushing (brushing too hard).
Sensitivity usually occurs when the enamel of your tooth is worn off exposing the inner sensitive layer called dentin. Consuming anything cold/ hot, sweet/ sour can act as stimulus at this point can cause extreme sensitivity in your tooth.

Key facts on dry mouth

One in eight people suffer from severe teeth sensitivity
