In the battle against tooth decay, fluoride is an important weapon. Since the discovery of its dental health benefits a century ago, fluoride has been credited with saving countless teeth.
But over its history in dental care, this natural-occurring chemical has also had its share of controversy with concerns raised from time to time on potential health dangers. These run the gamut from “conspiracy theory” speculations to credible research like a 2006 National Research Council study that suggested a possible increased risk of bone fracture or cancer from over-consumption of fluoride.
Even so, there is actually little evidence or even record of incidence for such dire consequences. The only definitive health effect from fluoride found after decades of copious research is a condition called fluorosis, a permanent staining effect on the teeth. Fluorosis poses a cosmetic problem but does not harm the health of the teeth.
Moderation in fluoride use seems to be the key to gaining its health benefits while avoiding fluorosis. One influential fluoride researcher, Dr. Steven Levy, estimates 0.05-0.07 milligrams of fluoride per one kilogram of body weight (about a tenth the weight of a grain of salt for every two pounds) is sufficient to gain the optimum dental benefit from fluoride.
The real question then is whether your family’s current consumption of fluoride is within this range. That will depend on a number of factors, including whether your local water utility adds fluoride to your drinking water supply and how much. You may also be ingesting fluoride through processed foods, juices and even some bottled waters. And you can encounter fluoride in dental care including toothpastes and clinical treatments.
One way to moderate your family’s fluoride intake is to be sure all your family members are using the correct amount of fluoride toothpaste for their age while brushing. Infants need only a slight smear on the end of the brush, while older children can brush adequately with just a pea-sized amount. For other tips and advice, talk to your dentist about your family’s fluoride intake and how you might adjust it.
Even with the possibility of fluorosis, fluoride still provides an incredible benefit in preventing tooth decay. By understanding fluoride and keeping your intake within normal ranges you can maximize its benefit for healthier teeth and minimize the fluorosis risk.

Since the 1950s fluoride has played an important role in the fight against tooth decay as an additive to hygiene products and many public water supplies. But although a proven cavity fighter, some have questioned its safety over the years.
To date, though, the only substantiated health risk from fluoride use is a condition known as enamel fluorosis, which occurs when too much fluoride is ingested during early tooth development as the mineral embeds in the tooth structure. Fluorosis can cause changes in the enamel’s appearance, ranging from barely noticeable white streaking to darker visible staining and a pitted texture.
Fluorosis is primarily a cosmetic problem and not a serious health issue. The staining on otherwise sound teeth, however, is permanent and more severe cases may require extensive bleaching treatment to improve appearance. The best strategy is to prevent fluorosis by monitoring and limiting your child’s fluoride intake, until about age 9.
Tooth decay is a more serious condition than fluorosis so we’re not advocating you eliminate fluoride but that you keep your family’s intake within safe levels. The first step is to determine just how much that intake is now, particularly if you drink fluoridated water. If you have public water, you may be able to find its fluoridation level online at apps.nccd.cdc.gov or call the utility directly.
You should also be careful about the amount of toothpaste your child uses to brush their teeth. Children under two need only a trace (a “smear”) on the brush, and children between the ages of 2 and 6 a pea-sized amount. And, they should brush no more than twice a day.
Another possible concern is infant formula, especially mixable powder. While the formula itself doesn’t contain fluoride, water mixed with it may. If you live in an area with increased fluorosis risk, consider breast-feeding (breast milk has little fluoride), using ready-to-feed formula, or mixing powdered formula with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
We’ll be glad to help assess your family’s current fluoride intake and advise you on making adjustments to bring it into normal ranges. Taking in the right amount of fluoride assures you and your children receive the most benefit and protection from it, while avoiding future smile problems.
