Children are very fond of sweets and colorful carbonated drinks, but they are often the cause of yellowness, plaque on the teeth, and then caries. My little patient is no exception. Approximately once every six months she visits me for preventive examinations, and this time we decided to do a tooth brushing, and enamel strengthening by fluorination. These procedures will not only return the whiteness of her smile, but also help prevent caries.
