Dental checks are the standard twice a year but not always the rule. Many people see a dentist twice a year since most dental insurance plans provide free preventive care, including basic cleanings and checkups. Your oral health needs depend on how often you or your child go. The main goal of checkups is to catch minor dental problems early on. Usually, this means twice-a-year exams, typically once every six months. Depending on your dental needs, your dentist may suggest you visit more or less depending on how well you take care of your teeth and gums.
