While the stomatologicalprofession states that dental fluorosis is only an aesthetic problem and nota health effect, this declaration is an assumption and not a fact. Certainly,dental fluorosis represents a toxic effect in the tooth cells, but it is askedif the tooth cells are the only body cells impacted by this effect. Motivatedby this controversial topic, a bibliographic review was made aimed mainly atgoing deep into the theoretical knowledge and the clinical characteristics ofthis affection that may manifest in a local or general way, and into the consequencesof the inadequate use of fluor in the human organism. It was concluded thatfluorosis is a disease that not only affects the dental structures and thatit can not only be defined by the stomatologists due to the dental affectionsit may produce, since in many occasions it is the first sign that the personhas been exposed to elevated levels of fluorine.
