If fluoride can be a problem, why is it added in our drinking water?

Good question: Long debated topic, but in a nutshell, in very controlled doses, which it is when added to water it is very beneficial to dental health. Extremists examples are not in controlled doses where it can be a problem.

High Risk: Fluoride can be a prob at higher concentrations but that will not come from your water. It is added to water as a preventative measure to reduce decay rates in large populations. It is added at less than 1ppm normally which makes it so that you will not exceed your daily intake limits of fluoride. It can be a touchy subject however the fact is that Fluoride reduces decay rates-prevents cavities.
