In April 2025, U.S. Health Secretary Robert F. Kennedy discussed fluoride and its future in the U.S. He announced plans to instruct the CDC to stop recommending water fluoridation nationwide. The ingredient has recently been brought to the spotlight, as Utah became the first state in the nation to ban public water fluoridation.
With more states considering a ban or reduction in water fluoridation, it’s not uncommon for dental patients to feel wary about the mineral’s efficacy. While you may be concerned, fluoride is a safe and reliable oral hygiene ingredient, essential for protecting your teeth against everyday wear and tear.

What is Fluoride?
Fluoride is a naturally occuring mineral found in water and food. However, most people know of this mineral as a common ingredient in most oral hygiene products. When incorporated into toothpaste, mouthwash, and floss, this mineral is used to help remineralize your teeth. When you eat and drink, the bacteria in your mouth eat the food particles, creating acid byproducts.
This acid attacks your enamel, weakening it and making it more susceptible to decay. When you use products with fluoride, you support the remineralization of your teeth. If you have a history of cavity development, choosing to incorporate these products into your everyday oral hygiene routine can help prevent future decay.
The Introduction of Water Fluoridation
While fluoride is found naturally in many spring water sources across the nation, the U.S. didn’t begin water fluoridation until 1945. That is when Grand Rapids, Michigan, began testing the addition of the mineral into treated water sources. Over the next 15 years, the National Institute of Dental and Craniofacial Research monitored tooth decay rates in schoolchildren.
With this research, they found a 60% drop in dental caries (cavities) in children born after the introduction of fluoridation. By 1969, 200 million people across the U.S. had access to fluoridated water. In 2012, 67.1% of the U.S. population had access to fluoridated water, with continual goals to raise this number and expand access.
Fluoride and Your Oral Hygiene Products
This mineral has long been recognized for its ability to strengthen tooth enamel and prevent caavities. One of the primary benefits of incorporating it into your oral hygiene routine is its proven effectiveness in preventing tooth decay. If used correctly, whether in toothpaste or mouthwash, it can strengthen enamel and reverse early signs of tooth decay.
This is what makes it so crucial for cavity prevention. Regular use of fluoride toothpaste has been shown to significantly reduce the risk of cavities in children and adult. It may also help minimize plaque buildup and slow the growth of harmful oral bacteria. Many major health organizations, including the American Dental Association (ADA) and the World Health Organization (WHO), support the regular use of these products for cavity prevention.
Finally, with its enamel strengthening properties, using fluoride-based oral hygiene products can also help reduce tooth sensitivity. Many people experience sensitivity as their enamel thins and the underlying nerves are exposed. With remineralization, these nerves are protected from exposure to food and drinks, decreasing everyday discomfort.
Are There Health Risks Associated with Using This Ingredient?
As more states consider reducing or prohibiting water fluoridation, people may worry that there is a risk of regular use of the mineral. While there is increased public concern, there are decades of research to support the use of this mineral. Most studies agree that regular use of these products is safe and effective in preventing tooth decay.
One study in 1990 found unequivocal evidence that fluoride use caused osteosarcoma in male rats. However, no studies have since have established a surefire connection between the mineral and cancer development. U.S. Health Secretary Robert F. Kennedy is, however, establishing a task force to continue heavy research into the mineral’s health impacts.
The only well-known potential side effect of excessive use is dental fluorosis. Individuals, specifically children, who consume excessive fluoride develop faint white spots across their teeth. While this does pose some cosmetic concern, it does not compromise the health and strength of your teeth.
Overall, the scientific community consensus is that fluoride is safe and beneficial when used as directed. It is an essential ingredient in everyday oral hygiene products, as it can protect you from preventable oral health conditions like cavities. If you want to keep your smile safe from potential decay, it’s essential that you incorporate it into your routine.
How Much Is Too Much?
It is important that you don’t overuse fluoride. There are a few ways to determine if you’re overusing the mineral, including:
- White Spots on Teeth: Especially in children, this may indicate dental fluorosis from excessive use during tooth development.
- Frequent Swallowing of Toothpaste: Young children may ingest toothpaste, leading to excessive exposure. It is best to monitor them during brushing to prevent this.
- Multiple Sources: Using fluoridated water, supplements, mouthwash, and toothpaste together may lead to overexposure.
- Stomach Discomfort: Swallowing a large amount of this mineral in your oral hygiene products may cause nausea or cramps.
- Check Labels: Ensure you’re using products with appropriate fluoride levels (typically 1,000–1,500 ppm for toothpaste).
