There is a new ingredient in toothpaste, developed by dentists, called Novamin. Novamin can reduce teeth sensitivity. Teeth can become sensitive when the 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 minimal value in tooth healthy. But in their rare ionic form, they can make teeth stronger and help eliminate tooth sensitivity.
