The Final Splash
Water fluoride has sparked debates, but understanding its facts helps clear the air. Fluoride, a naturally occurring mineral, strengthens teeth and prevents cavities. It's found in various water sources, including rivers, lakes, and oceans. Adding fluoride to public water supplies has significantly reduced tooth decay, especially in children. However, too much fluoride can cause dental fluorosis, leading to white spots on teeth. The World Health Organization recommends fluoride levels of 0.5 to 1.5 mg/L in drinking water. While some argue against fluoridation due to potential health risks, extensive research supports its safety and benefits. Knowing these facts empowers you to make informed decisions about your water consumption.
