Fluoride varnish is relatively inexpensive, easy to brush onto a child's teeth, and can be part of a positive first dental visit to help prevent tooth decay. In contrast, when very young children get cavities, it is difficult for them to sit still for dental treatment. Often, young children needing many fillings receive care in the operating room, at great expense to their family and with the additional risks posed by general anesthesia. We now have an easy, low-cost way to keep teeth healthy.
