How do I know if my child is getting enough fluoride?

Have your pediatric dentist evaluate the fluoride level of your child's primary source of drinking water. Fluoridated toothpaste is the most effective way to prevent tooth decay.  If your child is not getting enough fluoride internally through water (especially if the fluoride level is deficient or if your child drinks bottled water without fluoride), then your pediatric dentist may prescribe fluoride supplements. It is important to drink fluoridated water.
