Fluoride treatments can be beneficial for adults as well as children. In children, fluoride varnish is applied to teeth in order to harden enamel and prevent tooth decay. Many adult patients experience prompt relief from cold sensitivity when fluoride is applied to the root surfaces of their teeth. As we age, our gum tissue tends to shrink or "recede", exposing softer root surfaces called cementum. Not only are these surfaces softer and more susceptible to decay, but they can be very sensitive to cold or sweet foods. Modern fluoride applications are not just for children anymore. More and more adults are having fluoride applied to their teeth during their routine dental cleaning appointments. Please ask your dentist or hygienist if you think that topical fluoride applications may be useful for you.
