Dental Opinions, New Technology Provides Relief for Sensitive Teeth.
A new ingredient in toothpaste, developed by dentists, called Novamin, can dramatically reduce teeth sensitivity. Teeth become sensitive when gum tissue recedes,or tooth enamel wear down exposing a tooth’s roots. Roots contain small holes or tubules that lead to nerves. Novamin plugs up the holes cutting off contact with nerves and eliminating pain.
