If you take a sip of chilled iced tea, bite down on a candy bar or slurp some hot soup and a stinging electric sensation in one or more of your teeth sends you flying out of your seat then you’ve got “sensitive teeth” which is a rather mild name for what can be a wildly uncomfortable condition.
Hypersensitivity is sensation felt due to the exposure of the nerves inside the dentin of the teeth to the environment, particularly to extremes of temperature. The sensation can range from irritation all the way to intense, shooting pain. This sensitivity can be caused by several factors, including wear, decaying teeth or exposed tooth roots.
Hence depending upon the cause for tooth sensitivity, the cure would be a filling, gum coverage, tooth coating, desensitizing agents or laser desensitization.
