What is water fluoridation?
Fluoridation is adding a small, controlled amount of fluoride to drinking water to help prevent tooth decay. Where a system fluoridates, the operator doses it carefully and monitors the level, because too much or too little misses the goal. Not every system fluoridates, and it is optional for many.

How operators handle it
Where a system fluoridates, the operator adds fluoride to a target level and monitors it, keeping records. Dosing and safe chemical handling are the operator's responsibility.
Not universal
Not every public water system fluoridates. Where it is done, it is a deliberate, monitored treatment step, not a natural part of the water.
