Dental Fluorosis Is a Risk of Excess Flouride Exposure
The most common risk of excessive exposure to fluoride is dental fluorosis. This condition causes the enamel of the teeth to become discolored. In mild cases, the discoloration appears as barely noticeable white spots on the teeth. In more severe cases, the discoloration is darker and may even form pits in the teeth. Dental fluorosis is of the most risk during the stages of tooth development and is, therefore, most common in children under the age of eight. A CDC survey found that around a quarter of the U.S. population has mild dental fluorosis. While the condition is not harmful to the teeth or overall health, it can be unsightly and may require dental treatment to correct. Severe fluorosis requires very high levels of fluoride exposure, far higher than the levels you would be exposed to in drinking water or toothpaste. On the other hand, people in areas with naturally high fluoride levels in the ground and drinking water are at the highest risk of severe fluorosis. The condition is considered endemic in these regions, which means it regularly occurs there.
