Which statement is an exception regarding the truths about fluorosis and fluoride?

The statement regarding the high level of fluoride in toothpaste causing increasing fluorosis rates is an exception because current research indicates that while fluoride is effective in preventing dental caries, the incidence of dental fluorosis is more closely linked to overall fluoride exposure rather than solely toothpaste concentrations.

Toothpaste does contain fluoride, and while excessive use, particularly in young children who may swallow toothpaste rather than spitting it out, can contribute to fluorosis, the overall fluoride exposure from all sources (including community water fluoridation, dietary sources, and dental treatments) plays a more significant role. The recommendation is often to use a pea-sized amount of fluoride toothpaste for children and encourage spitting rather than swallowing, minimizing that risk.

In contrast, managing the risk factors associated with fluorosis is well established, as is the observation that slight fluorosis prevalence has been on the rise, which reflects the need for ongoing education about the appropriate use of fluoride products. The CDC's position on fluoride levels in water is primarily focused on optimizing dental health while preventing fluorosis, indicating a measured balance rather than a blanket reduction.
