Topical fluoride treatments help keep your child’s teeth cavity-free between visits by strengthening the enamel. Depending on your child’s age, the fluoride may be brushed onto your child’s teeth or put into a foam tray and allowed to sit on their teeth. For younger children, a fluoride varnish is brushed onto the teeth. Fluoride varnish hardens when it comes in contact with saliva, forming a hard film that is brushed off later that evening.
Older children usually have a tray loaded with foam fluoride placed in their mouths for a specific amount of time along with a suction straw to remove any foam overflow and saliva. When the time is up, your child is told not to eat or drink for at least 30 minutes to allow the fluoride to work.
