For those of you confused by this debate, Pluto was reclassified from a planet to a dwarf planet in 2006, when the International Astronomical Union came up with three requirements for an object to be classified as a planet.

Fluoride is added to the water in some countries like the USA, Ireland and Switzerland but not in many others like yours or mine.
We also get Fluoride from toothpaste and food like fish and tee.
But the amount of fluoride found in groundwater, measured in mg/L, is the most significant source and varies geographically.
Fluoride has positive effects against caries, but high concentrations can give you enamel stains and even higher concentrations have negative effects for bones. Se https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2F...
