A popular Sixties-era hair cream touted their product with the tagline, "A little dab'll do ya!" In other words, it didn't take much to make your hair look awesome.
Something similar could be said about fluoride. Tiny amounts of this "wonder" chemical in hygiene products and drinking water are widely credited with giving people a big boost in protection against tooth decay.
A Colorado dentist is credited with first noticing fluoride's beneficial effects early in the Twentieth Century. Although many of his patients' teeth had brownish staining (more about that in a moment), he also noticed they had a low incidence of cavities. He soon traced the effect to fluoride naturally occurring in their drinking water.
Fast forward to today, and fluoride is routinely added in trace amounts to dental care products and by water utilities to the drinking water supply. It's discovery and application have been heralded as one of the top public health successes of the Twentieth Century.
Fluoride, though, seems a little too amazing for some. Over its history of use in dental care, critics of fluoride have argued the chemical contributes to severe health problems like low IQ, cancer or birth defects.
But after several decades of study, the only documented health risk posed by fluoride is a condition called fluorosis, a form of staining that gives the teeth a brown, mottled appearance (remember our Colorado residents?). It's mainly a cosmetic problem, however, and poses no substantial threat to a person's oral or general health.
And, it's easily prevented. Since it's caused by too much fluoride in prolonged contact with the teeth, fluorosis can be avoided by limiting fluoride intake to the minimum necessary to be effective. Along these lines, the U.S. Public Health Service recently reduced its recommended amounts added to drinking water 0.7 milligrams per liter (mg/L) of water. Evidence indicated fluoride's effectiveness even at these lower amounts.
You may also want to talk with your dentist about how much fluoride your family is ingesting, including from hidden sources like certain foods, infant formula or bottled water. Even if you need to reduce your family's intake of fluoride, though, a little in your life can help keep your family's teeth in good health.

Tooth decay is perhaps the biggest danger your child's teeth can face. Not only can it rob them of primary teeth now, but the loss of teeth at this early age could also lead to future bite problems.
That's why it's important to reduce the risk of tooth decay through daily brushing and flossing and regular dental cleanings. You child may also benefit from another measure that enhances those other hygiene efforts—topical fluoride applied directly to tooth surfaces.
Fluoride is a naturally occurring chemical that's been demonstrated to strengthen tooth enamel against contact with acid, the main cause of tooth decay. Today, fluoride is added not only to toothpastes and other dental hygiene products, but also in minute amounts to drinking water supplies across the country.
Even if your child takes in fluoride through one or more of these sources, there may still be a benefit to a topical application. For one, topical applications are usually stronger than fluoride toothpaste or fluoridated water supplies and can have greater effect. And because fluoridated water is ingested first before traveling through the bloodstream to the teeth, directly applied fluoride can strengthen them much faster.
But are these stronger concentrations of topical fluoride safe? Studies have shown no long-term health risk, but there can be temporary side effects like stomach pain, vomiting or headaches if the patient accidently swallows too much of the solution during the application. These side effects, however, can be minimized through safety measures dentists put in place during the procedure.
One study by the Cochrane Oral Health Research Group seems to show that the long-term benefit of topical fluoride is well worth this minor risk of side effects. After reviewing several scientific studies involving thousands of patients, the group found an overall 28% reduction in decayed, filled or missing teeth over a number of years among those who received a topical fluoride treatment.
Because of these and other forms of evidence, fluoride applications in either gel, foam or varnish forms have become a routine part of preventive care for children. Discussing it with your dentist, you may find it could be an extra weapon for your child in fighting tooth decay.

Fluoride is an important part of your child's dental development. But if children take in too much of this important mineral, they could experience enamel fluorosis, a condition in which teeth become discolored with dark streaking or mottling.
That's why it's important to keep fluoride levels within safe bounds, especially for children under the age of 9. To do that, here's a look at the most common sources for fluoride your child may take in and how you can moderate them.
Toothpaste. Fluoridated toothpaste is an effective way for your child to receive the benefits of fluoride. But to make sure they're not getting too much, apply only a smear of toothpaste to the brush for infants. When they get a little older you can increase that to a pea-sized amount on the end of the brush. You should also train your child not to swallow toothpaste.
Drinking water. Most water systems add tiny amounts of fluoride to drinking water. To find out how much your water provider adds visit “My Water's Fluoride” (//nccd.cdc.gov/doh_mwf/Default/Default.aspx) online. If it's more than the government's recommendation of 0.70 parts of fluoride per million parts of water, you may want ask your dentist if you should limit your child's consumption of fluoridated drinking water.
Infant formula. Many parents choose bottle-feeding their baby with infant formula rather than breastfeed. If you use the powdered form and mix it with tap water that's fluoridated, your baby could be ingesting more of the mineral. If breastfeeding isn't an option, try using the premixed formula, which normally contains lower levels of fluoride. If you use powdered formula, mix it with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
It might seem like the better strategy for preventing fluorosis is to avoid fluoride altogether. But that can increase the risk of tooth decay, a far more destructive outcome for your child's teeth than the appearance problems caused by fluorosis. The better way is to consult with your dentist on keeping your child's intake within recognized limits to safely receive fluoride's benefits of stronger, healthier teeth.

Keeping your child’s teeth and gums healthy may sometimes seem like “one step forward, two steps back.” You do all the right things like daily brushing and flossing, and keeping sugar consumption to a minimum. But they’re still getting too many cavities.
We can add something else to what you’re already doing to decrease their cavity rate: apply a concentrated fluoride mixture (stronger than what’s found in toothpaste or drinking water) directly to their teeth. Studies have shown that topical fluoride is effective at reducing the risk of new cavities in children at high risk for decay, and may even reverse early decay.
Topical fluoride can be applied as a gel, foam or varnish. The particular method used depends on factors like the child’s age or the preference of the dentist. But any of the three methods can deliver a short-term, high dose of fluoride to the teeth.
As a result, the burst of fluoride strengthens tooth enamel against decay, with plenty of evidence of its effectiveness. As such, the American Dental Association recommends periodic topical fluoride applications for children older than 6, and especially those that appear to be at higher risk for decay.
You might, however, be concerned about the long-term health effects of these stronger concentrations of fluoride. Again, research indicates that the only long-term hazard associated with too much fluoride is a condition called fluorosis, which produces heavy tooth staining. Fluorosis, though, is more of an appearance issue and doesn’t harm the tooth itself. And it can be avoided in the case of topical fluoride by performing the procedure correctly and conservatively.
There’s also a short-term risk of a reaction to the fluoride mixture if the child swallows too much during the procedure, which could cause stomach upset and pain, vomiting or headaches. We can avoid this by using precautions like dental dams and other isolation methods to prevent the child from ingesting it.
Using proper precautions and procedures, topical fluoride is a safe and effective way to give your child added protection against decay. Avoiding this destructive disease can help ensure they’ll enjoy good dental health for the rest of their lives.

Protecting a child's primary (“baby”) teeth from tooth decay should be a top priority. If one is lost prematurely due to decay, it could cause the permanent tooth to misalign when it comes in.
The basic prevention strategy for every child is daily brushing and flossing and regular dental visits. But children at higher risk for decay may need more: Â additional fluoride applied to teeth enamel during office visits.
This natural mineral has been shown to strengthen enamel, teeth's protective layer against decay, especially during its early development. Enamel is composed of calcium and phosphate minerals interwoven to form a crystalline structure called hydroxyapatite. Fluoride joins with this structure and changes it to fluorapatite, which is more resistant to mouth acid than the original structure.
We mostly receive fluoride through fluoridated drinking water and dental care products like toothpaste. Topical fluoride takes it a step further with a stronger dose than found in either of these sources. It can be applied with a foam, varnish or gel using an isolation tray (foam or gel) or painted onto the enamel (varnish or gel).
But does topical fluoride effectively reduce the occurrence of decay? Research indicates yes: a recent review of 28 studies involving over 9,000 children found an average 28% reduction in decayed teeth in children who underwent topical fluoride treatments.
There is, though, one potential side effect: children who swallow the fluoride substance can become sick and experience headache, stomach pain or vomiting. This can be avoided with proper precautions when applying it; the American Dental Association also recommends using only varnish for children younger than 6 years. It's also recommended that children receiving gel or foam not eat or drink at least thirty minutes after the treatment (those who receive the varnish aren't restricted in this way).
Topical fluoride is most effective as part of an overall prevention strategy. Besides daily hygiene and regular dental visits, you can also help reduce your child's decay risk by limiting the amount of sugar in their diet. Sealants, which are applied to the nooks and grooves of teeth where plaque can build up, may also help.
