We've known for a long time that fluoride strengthens tooth enamel against decay. We've also learned that fluoride consumption early in life pays later dividends with healthier teeth.
But while fluoride has generally proven safe, too much ingested by young children could cause enamel fluorosis. This condition produces a mottled or streaked appearance in teeth ranging from faint white patches to darker, pitted staining. Fluorosis doesn't harm teeth, but it does make them less attractive.
To prevent this, it may be necessary with your dentist's help to monitor your infant's or young child's fluoride intake and keep it in check. That will depend in large part on where you live, as well as your child's hygiene and eating habits.
Like three-quarters of public water systems, your local utility may be adding fluoride to your drinking water. The amount is governed by federal guidelines, which currently recommend fluoride amounts of no more than 0.70 parts per million of water. The fluoride levels in your water could have an impact on your child's total fluoride intake. You can find out for sure how much fluoride is present in your water by contacting your water utility company.
Another major fluoride source is toothpaste and other hygiene products. You can control your child's fluoride exposure by limiting the amount of toothpaste on their brush. Children under two only need a “smear,” while those between two and six need only a pea-sized amount.
Processed foods can contain fluoride if fluoridated water was used in their production. In this case, replace as much of the processed food items in your family's diet as you can with fresh fruits, vegetables and other foods.
Along this line, if you have an infant you want to pay particular attention to feeding formula, especially the powdered form you mix with water. If you're concerned about the amount of fluoride in your water consider other infant feeding options. Besides breast-feeding in lieu of formula, you can also use ready-to-feed pre-mixed with water (usually lower in fluoride) or mix powdered formula with bottled water specifically labeled “de-ionized,” “purified,”Â “demineralized,” or “distilled.”
This can be a lot to keep up with but your dentist can advise you. Fluoride is still a potent weapon against tooth decay and a safeguard on your child's current and future dental health.

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.
