You may see a small white spot in the front teeth of your child. You may see a prominent white band on the teeth when a pretty girl smiles. Fluorosis is not a disease but it affects the way that teeth look. These “defect looking teeth” can be improved by special surface treatment with chemical and mechanical treatment named microabrasion. Cosmetic bonding will correct the appearance if the fluorosis is big and deep.
In the last editorial, I mentioned community water fluoridation. This month I am continuing with answers to questions.
Is it safe to use the tap water for my baby? All persons should know whether the fluoride concentration in their primary source of drinking water is below optimal (less than 0.7 mg/L fluoride), optimal (0.7-1.2 mg/L fluoride), or above optimal (greater than 1.2 mg/L fluoride). Use of water below 0.7 mg/L fluoride contributes to a very small risk of developing this condition. The risk increases with an increasing level of fluoride and depends on other factors, such as age and weight of the child and how much formula they drink each day. Contact your local water company or utility to learn the fluoride level in your water supply.
Is all bottled water low in fluoride? Most bottled water contains low fluoride concentrations; however much variation exists-some brands may contain optimal or higher levels. Currently there is no requirement to display the fluoride concentration on bottle labels. Water labeled as purified, distilled, deionized, demineralized or produced through reverse osmosis are always low in fluoride.
What types of infant formula may increase the risk for enamel fluorosis? Ready-to-feed formula contains little fluoride and does not contribute to enamel fluorosis. Those types of formula that require mixing with water-powered or liquid concentrates-can be the main source of fluoride intake depending upon the water source.
What can be done to reduce my child’s chance of developing fluorosis? CDC has developed recommendations to reduce the risk for enamel fluorosis. Remember, fluorosis can only occur during the time of enamel formation, before teeth come into the mouth. Young children who use multiple sources of fluoride such as fluoride toothpaste, dietary supplements, and water with optimal or higher natural fluoride have a higher risk for this condition.
