Fluoride is added to drinking water to reduce tooth decay while keeping exposure within safe limits, so the target concentration is chosen to maximize protective effects for most people who drink the water. In New York State, the designated target for fluoridated water is 1.0 mg/L. This level provides effective caries-prevention for the typical daily water intake in the state’s climate while staying within safety guidelines and avoiding the higher risk of dental fluorosis that can come with much higher concentrations. Lower levels would offer less protection, while significantly higher levels would be unnecessary and could increase fluoride exposure concerns.
