Sometimes cause of tooth sensitivity are, 1. Presence of caries in tooth, which is approximating dentinal or pulp layer. Rx: RCT with or without antibiotic. 2. Wear off of teeth structure, enamel or dentinal structure which is approximating pulpal exposure. Rx: restoration/RCT 3. Calculus depisition-->gingival inflammation -->sensitivity Rx : scaling. 4.pericoronitis irt third molar most commonly. Rx analgesic with or without antibiotic. In case it is not exposing/approximaring the pulp layer, use local application of SENSIGEL/TOOTH MIN,4-5 times/day,before food,not to swallow saliva during the ointment applied on tooth,spit out after 3-4 minutes. And rinse mouth thoroughly.

Pls get check the cause of sensitivity.. If there is wear of tooth structure, like abrasion, it has to be filled with restorative material to stop sensitivity....

Please go to dentist for clinical consultation, if u have teeth abrasions then u may required restoration
