Fluoride has long been recognized as one of the most effective tools in the fight against tooth decay. Backed by decades of scientific research, fluoride helps protect and strengthen enamel, making teeth more resistant to cavities and damage.

In most communities across the U.S., fluoride is added to public drinking water–a practice endorsed by the American Dental Association, the CDC, and other health organizations as safe and effective.

What Is Fluoride?

Fluoride is a naturally occurring mineral that comes from the element fluorine. It is found in water, soil, food, and even air. When introduced into your body through water or dental products, fluoride is absorbed into the tooth enamel, where it helps prevent decay—especially in growing children.

Why Fluoride Matters for Your Teeth

Your body uses fluoride during a process called remineralization, which rebuilds and strengthens areas of enamel damaged by bacteria and acids. Benefits include:

• Reduced risk of cavities

• Stronger, more resilient teeth

• Support for developing teeth in children

How You Get Fluoride

There are several sources of fluoride exposure:

• Public tap water (most communities add fluoride to promote dental health)

• Fluoridated toothpaste and mouth rinses

• Professional fluoride treatments at your dental office (gels, foams, varnishes)

• Foods and drinks like tea, seafood, and some bottled beverages

• Naturally fluoridated water from private wells in some areas

For children, topical and dietary fluoride can significantly reduce the risk of early tooth decay.

Is Fluoride Safe?

Yes—when used appropriately. Fluoride in drinking water and dental products is safe and effective. However, it’s important not to swallow fluoride-containing products like toothpaste or rinses.

What About Fluorosis?

In rare cases, overexposure to fluoride—usually during early childhood—can cause a condition called dental fluorosis, which appears as white spots or staining on the teeth. This is a cosmetic issue and doesn’t affect the health of the teeth.

To avoid fluorosis:

• Supervise children under 6 when brushing

• Use a pea-sized amount of toothpaste

• Avoid unnecessary fluoride supplements unless directed by your dentist
