There is no such thing as the best toothpaste. We recommend only products that have been ADA (American Dental Association) accepted or approved. The selection is usually made on a case-by-case basis, but the main consideration when selecting toothpaste is your child's age. This is due to the risk of fluorosis in younger children who swallow toothpaste during regular brushing. A child may face the condition called enamel fluorosis if he or she gets too much fluoride during the years of tooth development. Too much fluoride can result in defects in tooth enamel.
