The presence of this substance in the normal composition of all tissues and organs of the human body as well as deficiencies highlighted under certain circumstances support this aspect. They show both the positive effects of fluorine, such as the role of fluorine in increased calcium storing in the bones and teeth, and the negative effects, for example inhibition of phosphatases, (enzymes used in many metabolic processes). The double effect also appears in the use of fluorine in treatments, because when overcoming a critical threshold for the body it may produce adverse effects, sometimes leading to death. The present article analyzes these effects, the primary purpose being to raise awareness and identify the reactions of fluorine on the body.
