WHO Warns Excess Fluoride May Harm Children’s Health and IQ Levels

Fluoride, a naturally occurring inorganic mineral, plays a crucial role in oral health but can be harmful in excess. According to the World Health Organization, fluoride helps prevent cavities by strengthening tooth enamel and increasing resistance to acid. Globally, around 2.4 billion people suffer from dental caries in permanent teeth, while 486 million children are affected in primary teeth.

The WHO recommends controlled fluoride use through toothpaste, fluoridated water, and a low-sugar diet. However, excessive intake-especially in regions with high fluoride levels in groundwater like India-can lead to dental and skeletal fluorosis, bone deformities, and osteosclerosis, reports DNA India.

Beyond oral effects, studies cited by the US National Library of Medicine and published in The Lancet Neurology suggest fluoride may act as a neurotoxicant, potentially lowering IQ in children. Fluoride is found in dental products, drinking water, and some foods. Experts advise supervising children while brushing to prevent ingestion and avoiding excessive fluoride exposure from multiple sources.
