Answer 1

Well, the zingers you are feeling are not really electrical current, but fluid movement in your "pores" or your teeth called dentinal tubules in your enamel matrix. These pores of the teeth go from the outside straight through to the pulp of the tooth where your nerves and blood vessels house. When the fluid moves toward and away within the tubule a "zinger sensation occurs. Usually zingers happen most frequently with cold water, however this does happen with warm and hot water as well.
One recommendation is to ask your hygienist about the products Vanish 5% fluoride varnish and also Sooth Rx. These products' effects last about 6 months sometimes longer.
Another recommendation is to have a dentist evaluate your teeth. It could be sensitivity due to a microfracture or a beginning of cavities. If the dentist says there are microfractures in your teeth it could be due to grinding. For grinding, patients have a bite guard made for at night to prevent any further wear of teeth.
Hope this helps

a,
JACKLYN A IS CORRECT! YOU POSSIBLY HAVE EITHER RECEDING GUMS AROUND THOSE TEETH OR CROWNS WITH EXPOSED MARGINS THAT ARE OPEN TO THE EXPOSURE OF AIR OR COLD/HOT LIQUIDS.
THE FIX IS TO HAVE A DENTIST APPLY SOME DESENSITIZING MATERIALS OR BRUSH WITH SENSODYNE TOOTHPASTE WHICH CONTAINS A CHEMICAL TO BLOCK THE FLUID IN THE DENTIN MICRO TUBULES FROM CAUSING YOU PAIN.
