Yes. In recent years, there has been some concern that babies under age one may increase their odds of later developing fluorosis—a relatively harmless condition that can cause faint white lines on tooth enamel—by consuming too much fluoride. This caused some doctors to question whether parents should avoid making baby formula with fluoridated tap water.
Here’s what to do: Find out how much fluoride is in your primary source of drinking water—your pediatrician, dentist, or local water company should be able to tell you this. Based on the levels in the water, you and your doctor will determine a plan of action. Since fluorosis is not caused just by drinking tap water— it can also result from the additive effects from multiple fluoride sources—you should always consult with a physician before adding fluoride sources like oral supplements, toothpastes, and mouthwashes.
Though this may all seem a bit tricky to figure out, it’s important to remember the benefits of fluoride, such as preventing tooth decay and cavities.
