“Baby Fluoride Alert?”

The American Dental Association (ADA) has given its golden seal to brand name fluoridated toothpastes for their cavity 
fighting features. It’s no surprise really – topical use of fluoride has been proven to be effective at inhibiting tooth demineralization, promoting remineralization and inhibiting the growth of bacteria associated with tooth decay. Fluoride is marketed in the US as a bone fortifier and is administered at the dentist’s office for nearly all pre-adolescent teeth cleanings. Finally, the idea of fluoridated water may seem like a great thing to add to your new child’s water, because it fortifies teeth – but beware! What isn’t so well known is that the potential toxicity of fluoride is dangerous, and if swallowed in concentrated form or ingested over a longer period of time, it may have potentially damaging side effects.
In 1977, The Institute of Medicine (IOM) specified adequate intakes of fluoride of 0.01 mg/day for infants through 6 months, 0.05 mg/kg/day for children beyond 6 months of age, and 3 – 4 mg/day for adults, to prevent dental caries. Upper limits (UL) of 0.10 mg/kg/day in children less than 8 years old and 10 mg/day for those older than 8 are recommended for prevention of dental fluorosis. Similar levels have been endorsed by the American Dental Association (ADA, 1994) and the American Dietetic Association (ADA, 2000). What does this all mean? Fluoride has an affinity for calcified tissues. The trace amount of daily intake of fluoride is beneficial, but too much of it can result in patchy or mottled looking teeth, known as dental fluorosis (or brittle bones, known as skeletal fluorosis). Studies are needed for health researchers to investigate the relationship between intake levels and human health. 75% of our daily fluoride intake is from water or beverages, like tea and juices.
The fluoride content of a water supply is often described by the term ‘parts per million’ (ppm). 1 ppm = 0.1 milligrams of fluoride per 100 milliliters of water. About 1 ppm seems to be the optimal level of fluoride for a drinkable water supply; a litre of such water would provide 1 milligrams of fluoride. At 2 ppm, mottling of tooth enamel may occur. The actual condition of ‘fluorosis’ or excessive deposition of fluoride in bones is only present after prolonged consumption of 20 to 80 milligrams of fluoride per day.
Repeated exposure to fluorine in naturally-occurring forms (such as in fruits and other produce) is one thing, but overexposing your child to fluoridated baby formula (identifiable by needing to add water to the formula) could put your child’s appearance – and bodily health – at risk. The key take-home message for parents is to avoid added fluoridated liquids or even foods of any kind. No level of fluoride is perfectly safe, and ideally, we wouldn’t need to use it at all – however, fluoride’s teeth strengthening properties, when used in proper doses, can be a beneficial additive.
If your child does develop dark-spotted or mottled teeth after getting his or her primary teeth, pay close attention to their diet! Nutrition should be strictly monitored for fluoride ingestion (including toothpaste!) – if so, he or she should have perfectly clear, spotless permanent teeth erupting around age 5. Experts also agree that it is a good idea to test the water from your home water lines, to see if it is overly fluoridated. Simple take-home tests are available from your local water or health bureau, or can often give past and current fluoride level readings. Do your research to protect your child’s and your health.
