I have sensitivity in my molars while having cold water. Why?

Hello,

Welcome to icliniq.com.

It does call for concern no doubt, but you need to be careful now with that tooth at least. Sensitivity means your tooth's outer layer has been eroded, so you need to take care of a few things,

1. Do not over brush that tooth or tooth in that area.

2. Avoid taking very hot and very cold food as they may cause shock to the tooth.

3. Do warm water and salt rinse three to four times a day.

4. Must clean your mouth with fingers properly after every meal.

5. If you have any gastritis or stomach related issues, solve it sooner.

6. Do not overthink. It is no big deal. Do revert for more queries. Do follow-up after four to five days.
