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. There are many forms of preventive dentistry such as daily brushing and dental cleanings. To maintain optimal oral health, the American Dental Association (ADA) recommends visits to the dentist at regular intervals determined by a dentist. These practices are designed to ensure that teeth are clean, strong, and white.
