Hello sir, Dental sensation is response with cold water. What should i do to cure?

Kindly apply senstivity paste like senquel f two to three times a day over the affected portion for two weeks. If senstivity still persists kindly visit dentist as the cavity might be deep and might need a root canal treatment.

This could b either due to sensitivity due to loss of enamel surface or due to decay of tooth. Tooth decay can b treated by filling of tooth or by rct n capping of the decay is deep. Sensitivity can b reduced by using desensitizing toothpaste such as senquelf or sensodyne toothpaste by rubbing some amount of toothpaste onto your tooth surface n wait till 5 mins before rinsing it off. Get your teeth evaluated by dentist to know the cause of your problem n get treated accordingly. Regsrds.
