Fluoride therapy has been proven beneficial in maintaining optimal oral health, particularly in the prevention of tooth decay and hypersensitivity. Since the introduction of fluoride into public water supplies more than 50 years ago, the incidence of cavities has declined dramatically by strengthening developing permanent teeth. However, professional fluoride treatments, combined with daily home therapy, can often times improve dental health. Treatment options vary according to a patient's susceptibility to decay, level of tooth sensitivity, periodontal (gum) condition and number of cosmetic restorations.
