The symbols on a dental chart indicate what types of repairs a person has had performed on their teeth and what problems require treatment. Dentists usually differentiate prospective repairs from completed ones using two different colors, often blue and red. Which two colors the dentist uses, as well as the particular symbols she uses to indicate certain problems and procedures, can vary across individual dentists. Some dentists also use a third color, typically green, to indicate calculus, hardened plaque.
