Dear Lybrate user,
I think your meaning of power in you teeth is sensitivity problem. You have
dental caries or atrision or abrasion which is causing
thermal sensation. You need restoration (filling) of your decayed teeth. After restoration your sensitivity problem will be cure. You need scaling for clean your teeth. After scaling yellowish part will be removed from your teeth & your teeth will be natural white colour. Please consult to your
dentist for clinical diagnosis & needful treatment.
