That requirement has not changed, but what has changed is our diet. Today most foods are made with fluoridated water, and crops are sprayed with fluoridated water, which is absorbed into the plant. Experts say that when you add just one glass of fluoridated tap water to that, it will send your child's fluoride levels off the chart. The problem with putting it in the water supply is the unprecedented unregulated dosage. Some grape juices have a fluoride content of more than 1.7 parts per million, compared with one part per million in tap water.
Teas have between two and ten parts per million.
Soft drinks and juices that are bottled in areas where the public water supply is fluoridated also contain fluoride. The American Dental Association and American Academy of Pediatrics now recommend infants avoid fluoridated water and not use fluoridated toothpaste before age two. This increased incidence, coupled with the widespread potential for multiple sources of fluoride in the diet, has prompted the ADA and AAP to revise their recommendations for fluoride supplementation. Proponents say that tooth decay is less in communities with fluoridation than those without it and that fluoridation is the safest and most cost-effective method of reducing tooth decay in a community.
