A dental checkup is a routine visit to a dentist to assess the health of your teeth and gums. During this appointment, the dentist examines your mouth for any signs of cavities, gum disease, or other dental issues. X-rays may also be taken to get a clearer view of your teeth and jawbone. In addition to the examination, a dental hygienist typically performs a professional cleaning. This involves removing plaque and tartar buildup, which helps prevent tooth decay and gum disease. Regular checkups are important for maintaining good oral health and catching potential problems early.
