What fluoride level is considered moderate and beneficial for dental health?

The fluoride level considered moderate and beneficial for dental health typically falls within the range of 0.7 to 1.0 mg/l. This concentration is widely recognized and supported by dental health organizations as optimal for reducing the incidence of dental caries (cavities) while minimizing the risk of dental fluorosis, which is a condition that can occur from excessive fluoride exposure during tooth development.

At this level, fluoride is effective in enhancing the remineralization of tooth enamel and can inhibit the growth of harmful oral bacteria. This range strikes a balance where fluoride provides protective benefits for teeth without leading to adverse effects, making it a well-established guideline for fluoride concentration in community water supplies for promoting oral health.
