Continuous use of fluoridated water from birth can reduce the occurrence of carious lesions by what percentage?

Continuous use of fluoridated water from birth has been shown to significantly reduce the prevalence of dental caries, with studies indicating that the reduction in carious lesions can range from 40% to 65%. This statistic reflects the strong relationship between fluoride exposure and decreased incidence of tooth decay.

Fluoride works by helping to remineralize enamel, making it more resistant to acids produced by bacteria in the mouth. When children have access to fluoridated water from an early age, the benefits are cumulative, as fluoride continues to be incorporated into the developing teeth, enhancing their strength and resistance to decay.

The percentages listed in the other choices do not encompass the widely accepted range established by research in this area. The effectiveness of fluoridated water has been substantiated through numerous public health studies, thus affirming that the reduction rate of carious lesions can indeed reach 40% to 65% when fluoride is used consistently from infancy.
