A topical fluoride treatment is applied at the dentist office after your child has received a professional cleaning. Usually a fluoride gel or foam is placed in mouth shaped trays (affectionately known as duck trays) and inserted into the child’s mouth for her teeth to “soak” in for a few minutes. After fluoride application, we will ask your child not to eat or drink for at least 30 minutes to allow for optimum absorption. Fluoride can re-mineralize small imperfections in the tooth enamel by attracting calcium to the teeth. Fluoride can actually make teeth stronger! Years of research and use have proven fluoride to be a safe and effective means of fighting and preventing tooth decay.
