Visiting the dentist can be a stressful experience for many people, and for some the fear is that fluoride is being applied to their teeth. While fluoride is often recommended by dental professionals for its ability to prevent tooth decay, there has been an ongoing debate about its safety.
Fluoride is a naturally occurring mineral found in water, soil, and some foods. It is widely used in dental care because it helps strengthen tooth enamel and prevent cavities. The American Dental Association and the World Health Organization support fluoride due to its effectiveness in protecting teeth. As Is Fluoride Bad for You? explains, “Fluoride has been proven to help reduce cavities by demineralizing and strengthening tooth enamel.” It’s often added to drinking water and used in dental treatments to protect against decay.
Despite its benefits, fluoride has its critics. One concern is dental fluorosis, a condition that occurs when children consume too much fluoride, leading to spots or discoloration on their teeth. As the Cleveland Clinic notes, “Fluorosis can occur if a child swallows too much fluoride, especially during the years when their teeth are developing.” Some people also worry about long-term health effects, such as impacts on bones or the thyroid, from fluoride exposure, especially through drinking water. “The levels of fluoride added to public water are carefully regulated and are considered safe for most people,” (Cleveland Clinic, 2025). Research on these potential risks is mixed, and most experts agree that fluoride is safe when used properly. When used correctly, fluoride treatments at the dentist are generally safe and effective. However, excessive fluoride exposure can be harmful, particularly for young children who might swallow toothpaste. The Cleveland Clinic advises, “It’s important to use the right amount of toothpaste and follow your dentist’s guidance to avoid overexposure.”
Fluoride is a crucial part of dental care for many people, and the treatments used by dentists are considered safe when applied correctly. If you have concerns about fluoride, it’s a good idea to discuss them with your dentist to find the best approach for your oral health.
