In 2006 the American Dental Association issued this statement:

Recent developments led the ADA to develop the interim guidance. Last spring, the National Research Council released a report on naturally occurring fluoride in drinking water. While not the major focus of the report, research was cited that raised the possibility that infants could receive a greater than optimal amount of fluoridefrom reconstituted baby formula. Then, on Oct. 14, the FDA said bottlers could claim that fluoridated water can reduce the risk of dental cavities or tooth decay, but that this claim could not be used on water marketed to infants.More research is needed before definitive recommendations can be made, but, in the meantime, if parents and caregivers are concerned, the ADA’s interim guidance provides steps to simply and effectively reduce fluoride intake during a baby’s first year of life.

Essentially, the ADA supports the pediatricians’ recommendations on the benefits of breast feeding and notes that using ready-to-feed formula for bottle-fed babies will keep their fluoride intake under IOM limits. If using a product that needs to be reconstituted, parents and caregivers should consider using water that has no or low levels of fluoride.

However, the ADA has steadily retreated from this position. See ADA statements issued in 2007, 2009, and 2011.
