Episode description

On this Skeptical Sunday, Jessica Wynn brushes away fluoride fears and gets to the root of this controversial mineral's cavity-fighting powers!

• Fluoride is a naturally occurring mineral found in water, soil, and food that helps prevent tooth decay by strengthening tooth enamel and making teeth more resistant to acid. When added to water supplies at controlled levels, it has been shown to reduce cavity rates by 40-70% in children.
• The discovery of fluoride's benefits came from investigating "Colorado Brown Stain" in the early 1900s, where researchers found that while high fluoride levels stained teeth brown, it also made them remarkably resistant to decay. This led to research determining safe, effective fluoride levels for water supplies.
• Despite widespread scientific consensus on its safety and effectiveness, fluoride remains controversial, with some groups claiming health risks. However, extensive research has found no evidence linking properly fluoridated water to cancer, bone problems, or other serious health issues at recommended levels.
• The optimal fluoride level in water has been adjusted over time as other sources of fluoride (like toothpaste and food products) have become more common. In 2015, the US Public Health Service lowered its recommended levels, showing ongoing monitoring and adjustment of public health policies.
• You can take control of your dental health by understanding your local water fluoride levels (easily found on the CDC website), using fluoride toothpaste appropriately, and making informed choices about water filtration — while remembering that every $1 spent on water fluoridation saves about $38 in dental healthcare costs!
