RE: Why the teeth become sensitive and what to do about it

in #health7 years ago

Contrary to popular belief, sensitivity is not enamel, and dentin – the tissue that lies underneath the enamel. The dentin is permeated with microscopic tubes within which pass the nerve endings. As long as these tubes are closed, even thinning enamel will not cause the person great discomfort. But if they exposed, the nerve endings react to any stimulus, from-for what there are unpleasant sensations.
