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.

In the early 1900s, a Colorado dentist noticed his patients had fewer cavities than the norm. He soon found the cause: naturally occurring fluoride in their drinking water. That discovery led to what is now heralded as one of the most important public health measures of the last century — the use of fluoride to prevent tooth decay.
While you're most likely familiar with fluoride toothpaste and other fluoridated hygiene products, there are other sources of this chemical you should know about — especially if you're trying to manage your family's fluoride intake. Here are 3 of these common sources for fluoride.
Fluoridated drinking water. Roughly three-quarters of U.S. water utilities add fluoride to their drinking water supply under regulations governed by the Environmental Protection Agency. The federal government currently recommends 0.7 milligrams of fluoride per liter of water as the optimum balance of maximum protection from tooth decay and minimal risk of a type of tooth staining called dental fluorosis. You can contact your local water service to find out if they add fluoride and how much.
Processed and natural foods. Many processed food manufacturers use fluoridated water in their processes. Although not always indicated on the packaging, there are often traces of fluoride in cereals, canned soups, fruit juices or soda. Many varieties of seafood naturally contain high levels of fluoride and infant formula reconstituted with fluoridated water can exceed the level of fluoride in breast or cow's milk. Beer and wine drinkers may also consume significant levels of fluoride with their favorite adult beverage, particularly Zinfandel, Chardonnay or Cabernet Sauvignon wines.
Clinical prevention measures. As part of a child's regular dental treatment, dentists may apply topical fluoride to developing teeth, especially for children deemed at high risk for tooth decay. This additional fluoride can be applied in various forms including rinses, gels or varnishes. The additional fluoride helps strengthen a child's developing enamel and tooth roots.
How much fluoride your family ingests depends on a number of factors like your drinking water, food purchases and dental hygiene products and procedures. If you have any concerns about how much fluoride you're encountering in your daily life, please be sure and discuss them with your dentist.

Since the discovery a century ago of its beneficial effect on tooth enamel, fluoride has become an important part of tooth decay prevention. It's routinely added to toothpaste and other hygiene products, and many water utilities add minute amounts of it to their drinking water supplies. Although there have been questions about its safety, multiple studies over the last few decades have eased those concerns.
Children especially benefit from fluoride during their teeth's developing years. Some children are at high risk for decay, especially an aggressive form known as Early Childhood Caries (ECC). ECC can destroy primary (baby) teeth and cause children to lose them prematurely. This can have an adverse effect on incoming permanent teeth, causing them to erupt in the wrong positions creating a bad bite (malocclusion).
For children at high risk for decay, dentists often recommend applying topical fluoride directly to the teeth as added protection against disease. These concentrations of fluoride are much higher than in toothpaste and remain on the teeth for much longer. Topical applications have been shown not only to reduce the risk of new cavities, but to also stop and reverse early decay.
Children usually receive these applications during an office visit after their regular dental cleaning. There are three different ways to apply it: gel, foam or varnish. To prevent swallowing some of the solution (which could induce vomiting, headache or stomach pain) the dentist will often insert a tray similar to a mouth guard to catch any excess solution. Varnishes and a few gels are actually painted on the teeth.
The American Dental Association has intensely studied the use of topical fluoride and found its application can result in substantial decreases in cavities and lost teeth. They've concluded this benefit far outweighs the side effects from ingesting the solution in children six years and older. With proper precautions and waiting to eat for thirty minutes after an application, the possibility of ingestion can be reduced even further.
While topical fluoride can be effective, it's only one part of a good dental care strategy for your child. Consistent daily brushing and flossing, a nutritious diet low in added sugar, and regular dental visits still remain the backbone of preventive care.
