Rethinking the Future of Caries Prevention

Dental caries, a global public health crisis, necessitates continuous evaluation of preventive measures. For decades, fluoride has been the gold standard of caries prevention, recognized for its ability to strengthen enamel and promote remineralization.¹ However, modern concerns regarding systemic toxicity and dental fluorosis have driven interest in biomimetic alternatives, most notably hydroxyapatite — the fundamental mineral component of teeth and bone.^2,3 This article contrasts the mechanisms, clinical efficacy, and safety profiles of fluoride and hydroxyapatite in the context of professional oral care recommendations.

Any discussion of fluoride should recognize that its well-documented benefits overwhelmingly outweigh concerns, particularly when evaluated alongside its strong safety record despite ongoing public debate. Much of the debate stems from concerns about potential systemic effects, perceived overexposure through multiple fluoride sources, and longstanding skepticism toward community water fluoridation programs. Critics argue that population-wide fluoridation may pose risks, such as dental fluorosis or other health effects, while evidence suggests that these risks are generally minimal at recommended levels and are outweighed by fluoride’s proven protective role against caries.⁴
