Expert Verdict

Fluoride toxicity risk if ingested in excessive amounts (particularly in children). Chronic overexposure can cause dental or skeletal fluorosis.. Inhibits enamel demineralization while supporting remineralization; lower solubility compared to sodium fluoride, which affects bioavailability.
