Fluorosis is a condition caused by excessive fluoride exposure, which can lead to dental and skeletal issues. While fluoride in recommended doses benefits dental and skeletal health, its toxicity at higher levels has been widely reported. The World Health Organization estimates that around 260 million people globally live in areas with excessive fluoride levels in drinking water, exceeding 1.5 mg/L. In India, fluorosis has been a recognized issue for over 85 years, with initial cases detected in Nellore district, Andhra Pradesh, and the Madras Presidency during British rule. Prevention of fluorosis is best achieved through safe drinking water and nutritional interventions, including the intake of vitamin C, vitamin E, calcium, and antioxidants. Source-supported facts: Fluorosis is a disease caused by ingestion or inhalation of Fluoride in excess, which the human body is unable to tolerate. WHO has estimated that around 260 million people inhabit locations having excessive Fluoride levels in drinking water (>1.5 mg/L) globally. Fluorosis has a history of about 85 years in India. Excess Fluoride in groundwater and prevalence of Fluorosis was detected in British India in Nellore district of Andhra Pradesh and in Madras Presidency. Prevention of fluorosis is best achieved through safe drinking water and nutritional interventions.
