What is the effect of fluoridating water on community health?

Fluoridating water primarily serves to improve community health through the significant reduction of dental decay. Fluoride, a naturally occurring mineral, is known for its ability to strengthen tooth enamel and make teeth more resistant to the harmful effects of acid produced by bacteria in the mouth. When fluoride is present in drinking water, it becomes beneficial in preventing cavities, particularly in children whose teeth are still developing. The consistent exposure to fluoride helps to remineralize teeth and inhibit the growth of harmful bacteria, leading to a decreased incidence of tooth decay and the associated dental treatment costs.

The other options suggest negative health effects that are not substantiated by the evidence supporting the practice of water fluoridation, which highlights its protective benefits against dental caries.
