This was interesting. We had the fluoride conversation in the office a couple of times this past week, and I know that everyone has to make up their mind about which side of the fence to be on, but a recent study showed that proper amounts of fluoride were beneficial in adults.
Study Links Fluoride Exposure To Enhanced Cognitive Performance In Adolescents
Dental Tribune International (12/2) reported that a new study published in Science Advances on November 21, 2025, found that adolescents exposed to recommended fluoride levels in drinking water demonstrated better cognitive performance in mathematics, reading, and vocabulary. Conducted using the High School and Beyond cohort dataset, the study analyzed over 58,000 students and found positive associations with cognitive outcomes in adolescence, though effects in later adulthood were smaller. The research challenges claims of cognitive harm from typical fluoridation and supports ongoing water fluoridation policy debates.
What is the appropriate amount of fluoride inthe diet? Dental organizations have agreed that 0.7ppm in drinking water is the optimum level. So what amount are you getting in your water? If you drink tap water, then you need to know what amount is in your tap. A water report for your area can be requested from the city or the county. If you drink bottled water with fluoride in it, the amount may be listed on the label or it can be found on the company website.
The most important thing to remember is that systemic fluoride is necessary while the teeth are developing, and topical fluoride is necessary to help keep the teeth resistant to decay after eruption. I'm a firm believer in fluoride, and I respect those who are not users of it. Plaque is the beginning of the two evils in the mouth - cavities and gum disease. If you can keep the plaque from building on the teeth, you stand a better chance at reducing your chances of cavities and periodontal disease. As one of my hygienists used to say - BRUSHA BRUSHA BRUSH-AH!!! I always wanted her to add in - FLOSSA FLOSSA FLOSS-AH!!! as well.
