Regular dental check-ups are essential to keep your teeth and gums healthy. Screening for cavities is just one part of a thorough dental check-up, which also includes checking the condition of the teeth and gums, and looking for lesions and signs of disease. At the end of the examination, the dentist will provide information about the health of the teeth and gums and make any recommendations. The dentist should be visited every six months for routine check-ups and dental cleanings.
