what is the definiton of floride?

did you mean Fluoride which:

Fluoride is the reduced form of fluorine. Both organic and inorganic compounds containing the element fluorine are considered fluorides. As a halogen, fluorine forms a monovalent ion (−1 charge). The range of fluorides is considerable as fluorine forms compounds with all elements except He and Ne[1][2]. Fluorides range from severe toxins such as sarin to life-saving pharmaceuticals such as efavirenz and from refractory materials such as calcium fluoride to highly reactive sulfur tetrafluoride.

Fluoride is a major intellect suppressant that is being added to drinking water supplies and toothpaste. Sodium fluoride is a common, ingredient in rat and cockroach poisons, anesthetics, hypnotics, psychiatric drugs, and military nerve gas. It is one of the basic ingredients in Prozac and the Sarin nerve gas used in the attack in the Japanese subway system. Independent scientific evidence has claimed that fluoride causes various mental disturbances and makes people stupid, docile, and subservient. This is besides shortening life spans and damaging bone structure.
