There is a new ingredient in toothpaste, developed by dentists, called Novamin. Novamin can reduce teeth sensitivity. Many times teeth become sensitive when gum tissue recedes, exposing a tooth’s roots. Roots contain small holes or tubules that lead directly to the tooth nerves. Novamin plugs up the holes cutting off contact with nerves and eliminating pain. It is made from a compound from elements naturally critical for bone and tooth mineralization: calcium, phosphorus, silica and sodium. In their common forms, these elements have very limited value in tooth healthy. But in their rare ionic form, they can make teeth stronger and help eliminate tooth sensitivity.
