Does Your Tap Water
in Denver Contain Fluoride?

Many communities across the country add fluoride to drinking water to support dental health, and Denver is no exception. Fluoride levels in Denver’s tap water are typically maintained around 0.7 mg/L (ppm), which aligns with federal recommendations for cavity prevention.

While this level is considered safe and effective, some homeowners still prefer to better understand their exposure or explore filtration options based on personal preference.

Many communities are taking a second look at fluoridation levels and motivations, and as the debate continues, it’s a good idea to know some basics about fluoride and its legacy in this country.

The U.S. Department of Health and Human Services Agency (HHS) revised what defined acceptable fluoride levels:

“…water systems practicing fluoridation adjust their fluoride content to 0.7 mg/L (parts per million), as opposed to the previous temperature-dependent optimal levels ranging from 0.7 mg/L to 1.2 mg/L. There is no change regarding federal health officials’ strong and long-standing support regarding the value of fluoridation of drinking water.”

Since plant life relies heavily on water, most forms of plants and vegetation contain various levels of fluoride.

The most common use for artificially-created fluoride is the treatment of cavities and supporting dental health. Fluoride has been widely shown to prevent, and even reverse, tooth decay, and has been added to many city water supplies throughout the country as a result.

Fluoride has been added to public water systems in the United States for decades as a way to support dental health. Today, most systems target a level of 0.7 ppm, which is considered optimal for reducing tooth decay while minimizing potential risks.

In Denver, fluoride levels are generally consistent with this target. Even so, concerns about long-term exposure or individual sensitivity continue to drive interest in home water filtration solutions.

While many studies support the benefits of fluoridated water, fluoride in drinking water is not without its critics. For example, recent studies have linked increased fluoride consumption in pregnant women to reduced IQ levels in their children, while other, less alarming studies simply fail to corroborate the dental hygiene benefits of fluoridated water.

If you’re looking to reduce fluoride in your tap water, there are treatment options specifically designed to address it.

This is a consideration for some Denver homeowners who want more control over what’s in their drinking water, even when levels fall within recommended guidelines.

Effective fluoride removal options include:

Standard carbon filters are typically not designed to remove fluoride, so choosing the right system is important.

At recommended levels, fluoride is widely recognized for helping prevent tooth decay and supporting dental health.

However, higher levels of long-term exposure have been associated with:

While Denver’s levels aren’t egregious, some homeowners prefer to reduce fluoride intake as part of their overall water quality strategy.

Even when water meets federal standards, many homeowners choose filtration for added control over their drinking water.

In Denver, common reasons include:

Reverse osmosis systems are one of the most common solutions used to reduce fluoride levels at the point of use.
