In addition to hygiene treatment and maintenance during your regular oral examinations, Dr. Dean offers fluoride treatment to help inhibit tooth decay. Fluoride is a mineral naturally found in water and other foods; it makes teeth more resistant to acid from oral bacteria and sugars. It can also reverse the effect of early tooth decay. Your dentist can prescribe fluoride supplements, or apply it directly to the teeth in the form of a gel, foam or varnish. Fluoride treatment may be necessary for people who suffer from chronic dry mouth, the early stages of gum disease, or a history of frequent cavities.
