The periodic dental check-up is a routine examination in which the dentist systematically inspects a patient’s mouth for any abnormalities. During the examination, the teeth, molars, gums, mucous membranes, palate, tongue and other essential parts of the mouth are inspected. If abnormalities are detected, the dentist may perform follow-up examinations or refer to a specialist for further treatment. The periodic check-up is important to prevent or treat problems such as cavities, gingivitis, discoloration, changes to the bite, infections or other conditions before they get worse.
