Fluoride in drinking water is considered safe and beneficial for dental health when used at recommended levels. The practice of adding fluoride to water supplies is known as water fluoridation and is aimed at reducing tooth decay. Numerous health organizations, including the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and the American Dental Association (ADA), support the use of fluoride in drinking water for its role in preventing cavities. However, like many substances, fluoride can be harmful in excessive amounts. High levels of fluoride consumption can lead to dental fluorosis, which is usually mild and appears as white spots on the teeth. In much rarer cases, excessive fluoride exposure can lead to skeletal fluorosis, affecting bones and joints. It's important for water fluoridation to be maintained at optimal levels, typically around 0.7 parts per million (ppm) in the U.S., to balance the benefits of cavity prevention with the risk of overexposure. Local water suppliers are responsible for monitoring and adjusting fluoride levels to ensure safety and effectiveness.

**Yes, fluoride in drinking water is considered safe and effective** when maintained at recommended levels. ### **Background** Fluoride is often added to public water supplies to help prevent tooth decay. Studies over many decades have shown that communities with fluoridated water have lower rates of dental cavities. ### **Safety and Guidelines** - **U.S. recommendations:** The U.S. Public Health Service recommends a fluoride concentration of **0.7 milligrams per liter (mg/L)** (or parts per million, ppm) as optimal for preventing tooth decay and minimizing risk of adverse effects. - **World Health Organization:** The WHO states that **up to 1.5 mg/L** in drinking water is considered safe. ### **Potential Health Risks** - **Dental fluorosis:** Mild white spots on teeth can occur if children (under about 8 years old) consume too much fluoride while their teeth are developing. This is usually cosmetic and not harmful. - **Skeletal fluorosis:** This rare condition, causing joint stiffness and pain, may occur only from long-term consumption of **much higher amounts** (above 4 mg/L). - **Cancer and other risks:** Extensive research has **found no convincing evidence** linking optimally fluoridated water to cancer, neurological disorders, or other serious health problems. ### **Expert Endorsements** Fluoridation is supported by organizations such as: - World Health Organization (WHO) - Centers for Disease Control and Prevention (CDC) - American Dental Association (ADA) ### **Summary Table** | **Fluoride Level (mg/L)** | **Effect** | |---------------------------|--------------------------------| | 0.7 (U.S. recommended) | Prevents tooth decay, safe | | 1.5 (WHO guideline) | Upper safe limit | | >2.0 | Dental fluorosis risk increases| | >4.0 | Skeletal fluorosis risk | --- ### **Conclusion** **Fluoride in drinking water is safe for people of all ages when present at recommended levels.** It is one of the most effective public health measures for preventing dental decay. #### **References and for More Information:** - [CDC: Community Water Fluoridation Safety](https://www.cdc.gov/fluoridation/faqs/safety.html) - [WHO: Guidelines for Drinking-water Quality](https://www.who.int/news-room/fact-sheets/detail/fluoride-in-drinking-water) - [American Dental Association: Fluoridation Facts](https://www.ada.org/resources/research/science-and-research-institute/oral-health-topics/community-water-fluoridation) If you have concerns about local water quality, you can request a report from your water supplier or use home testing kits.

The safety of fluoride in drinking water is a topic of ongoing debate. Fluoride is added to public water supplies in many communities to prevent tooth decay, a practice known as water fluoridation.
