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.

Your family uses fluoride toothpaste and your drinking water is fluoridated too. So with the fluoride your child already takes in, is it really necessary for topical fluoride treatments during their regular dental visits?
The answer is most definitely. Fluoride has a unique ability to strengthen enamel, your teeth’s protective cover against decay and other diseases. It does this by infusing itself in the enamel structure and making it that much more resistant to acid attack and decay.
This infusion occurs in two ways. First, growing teeth obtain it through the bloodstream as they incorporate other minerals that make up the enamel structure. The very small amount of fluoride added to drinking water — as low as one part per million (ppm) — imparts sufficient fluoride to developing teeth. In the absence of fluoridated water, dietary fluoride supplements can achieve the same effect.
The second way is just after the teeth have erupted and are still quite young. In this case, fluoride coming in direct contact with the enamel surface is absorbed, resulting in changes to the enamel’s crystalline structure that will create added strength. This can occur to a limited degree through fluoride toothpaste or other dental products. The concentration of fluoride in these products, though, is relatively low (850-1500 ppm) as mandated by the U.S. Food and Drug Administration for safety.
Professional applications, on the other hand, are much higher — 12,300 to 22,600 ppm depending on their form. They’re applied, of course, under strict clinical guidelines to cleaned tooth surfaces, usually as a gel, foam or varnish. The latter form will often continue leaching fluoride into the enamel for a month or more.
These topical applications can greatly strengthen the teeth of children who don’t have the benefit of fluoridated water or may be at higher risk for dental disease because of socio-economic conditions. But they can still be helpful for children with adequate fluoride exposure and low risk factors for disease. At the very least, fluoride treatments can give your child an added boost of protection as their teeth continue to develop.

Prior to his first appearance on the Oprah Winfrey show, interior designer Nate Berkus knew immediately that he was not there to pick sofa colors and paint chips. Instead, he was there to lift people up through the way they live. And boy, did he do just that. Over the next eight years, Berkus completed 127 makeovers and became one of America's most beloved go-to guys for inspiration on the latest design trends.
During a recent interview with Dear Doctor magazine, Nate discussed his career as well as his oral healthcare. He credits his dazzling all-natural smile — no cosmetic dentistry here — to the treatments he received as a child from his dentist. “I'm grateful for having been given fluoride treatments and sealants as a child.” He then added that, “healthy habits should start at a young age.” Nate is still in the habit of brushing his teeth two or three times a day. As for flossing his teeth, he credits his dentist with the advice he still follows: “Floss the ones you want to keep.”
Many parents and caregivers may not be aware of the important role fluoride treatments play in protecting children's teeth. Fluoride has the unique ability to strengthen tooth enamel, the hardest substance found in nature. Depending on where you live, you may have fluoridated tap water. You may also have fluoride in your toothpaste, depending on the brand you use. Both of these are beneficial, but sometimes we recommend additional fluoride treatments based on the specific needs of your children. Why? The concentrations of the topical fluorides we typically apply are much higher than what is found in toothpastes, and we apply them for a longer period of time. For example, we often apply them for four minutes per treatment session.
