What is the desirable concentration of Fluoride in drinking water?

The desirable concentration of fluoride in drinking water is typically recommended to be between 0.8 and 1 mg/L. This concentration range is endorsed because it provides benefits for dental health by helping to reduce the incidence of tooth decay, while also minimizing the risk of dental fluorosis, which can occur at higher concentrations. The practice of adjusting the fluoride level aims to balance the protective benefits against potential adverse effects, making it vital to stay within this specific range.

Concentrations below this range, such as those found in other options, may not provide enough benefit for dental health, and higher concentrations could lead to adverse health effects. Thus, maintaining fluoride levels within this range is crucial for public health safety and effectiveness.
