Water fluoridation reduces cavities but excessive fluoride intake may pose health risks, including bone and neurological issues. Epidemiological studies confirm safety at dental dosages.

Area of Science:

  • Biochemistry
  • Toxicology
  • Public Health

Context:

  • Domestic water fluoridation is a long-standing public health measure to prevent dental caries.
  • Increased fluoride intake from food and beverages prepared with fluoridated water raises concerns about potential adverse health effects.

Purpose:

  • To review the potential adverse health effects associated with chronic fluoride exposure from various sources.
  • To evaluate the impact of fluoride on bone metabolism, testicular function, and neurological activity.

Summary:

  • Fluoride's affinity for calcified tissues affects bone health, potentially causing joint pain, ligament calcification, and osteosclerosis by influencing growth factors and hormones.
  • Sodium fluoride may impair testicular activity through oxidative stress and inhibition of androgenesis-regulating enzymes.

  • Insoluble calcium fluoride can lead to hypocalcemia, secondary hyperparathyroidism, bone resorption, and potentially affect phosphorus levels.
  • High fluoride doses may cause neurological symptoms and reduced motor activity by decreasing nicotinic acetylcholine receptors.

    • Impact:

    • Findings highlight the need for careful consideration of total fluoride intake beyond dental applications.
    • Epidemiological data suggests fluoride is safe at recommended odontoiatric (dental) dosages, balancing benefits against risks.
