Preventive dentistry is the practice of caring for your teeth to keep them healthy. This helps to avoid cavities, gum disease, enamel wear, and more. You should see your dentist at least once per year for an exam to check for any problems in the teeth or gums. If you’re at a high risk for dental problems, you’ll likely benefit from more frequent dental visits. If you’re at a low risk for dental problems, you may see the same benefits from only one cleaning per year. Dental cleanings and exams allow dentists to identify problems and take care of them right away.
