The American Academy of Pediatric Dentistry updated their fluoride recommendations in 2012: “Children at moderate caries risk should receive a professional fluoride treatment at least every 6 months; those with high caries risk should receive greater frequency of professional fluoride applications (ie, every 3-6 months).”
Fluoride is a very helpful preventive aid against cavities although children don’t always love the professionally-applied kind since it is in a very high concentration. The professionally-applied fluoride in combination with fluoridated water and fluoridated toothpaste is a great tool in the battle against tooth decay.
