Dietary Sources of Fluoride
Fluoride can be obtained from various dietary sources. Foods that are grown in soil and water containing fluoride may retain small amounts of fluoride after being harvested. It is worth noting that cooking food in fluoridated water can further elevate the fluoride content in the food.
Another natural source of fluoride is the ocean, where it is present in the form of sodium fluoride. Consequently, most seafood contains some level of fluoride. Furthermore, certain types of tea and gelatin also contain trace amounts of fluoride. Breast milk naturally contains minimal amounts of fluoride, while additional fluoride is supplemented in formula milk for babies.
Recognizing Excessive Fluoride Levels
Recognizing the signs of excess fluoride is crucial for maintaining optimal oral health. In 2015, authorities in the United States made the decision to lower fluoride levels in water to 0.7 parts per million nationwide. This measure was taken to minimize the risk of dental fluorosis, a condition characterized by permanent white spots or marks on the teeth, a chalky appearance, and the development of pits and surface irregularities on dental enamel. It is important to note that dental fluorosis primarily affects children aged 8 or below.
