Fluorosis is a cosmetic defect that occurs when more than an optimal amount of fluoride is ingested.
The result of mild fluorosis is light spots on permanent teeth that develop while the teeth are still forming. The researchers analyzed the fluoride concentration of 238 commercially available infant foods. One of the reasons for the high fluoride concentrations in infant foods with chicken may be because of the processing method, according to the study. The mechanical deboning process may leave skin and residual bone particles in the food. The researchers also found that dry infant cereals that are reconstituted with fluoridated water may noticeably increase the levels of fluoride in a child's daily intake.
