The Dark Side of a Bright Smile: Fluoride in Your Water

by The Clean Water Company

For decades, fluoride has been added to many public water supplies in the United States. The idea was simple: strengthen teeth and reduce cavities. While that intention may sound positive, growing research shows that too much fluoride can carry serious health risks — especially with long-term exposure.

At The Clean Water Company, we believe families deserve to know what’s in their water so they can make informed choices. Here’s a closer look at fluoride in tap water, its potential side effects, and how to protect your home.

Why Is Fluoride Added?

Public water systems began adding fluoride in the 1940s after studies suggested it helped prevent tooth decay. Today, around 70% of Americans receive fluoridated tap water.

The Potential Negative Effects of Fluoride

• Dental Fluorosis
  Overexposure in children can cause white streaks, spots, or in severe cases, brown stains and pitting of tooth enamel.

• Skeletal Fluorosis
  High, long-term intake (usually from naturally fluoridated water sources) may lead to joint pain, stiffness, and bone changes.

• Endocrine Concerns
  Some studies link fluoride exposure to thyroid problems, particularly in people who are already low in iodine.

• Neurological Risks
  Recent research suggests that children exposed to high levels of fluoride may face a higher risk of lowered IQ or changes in brain development.

• Kidney and Bone Health
  Those with reduced kidney function can’t filter fluoride effectively, which may cause buildup in the body. Some studies also suggest a connection between fluoride and increased fracture risk.

How Much Fluoride Is Too Much?

• EPA limit: 4.0 mg/L

• CDC’s target for cavity prevention: 0.7 mg/L

• Most water districts aim for 0.7 mg/L — but even this “safe” level is now under debate.

How to Remove Fluoride From Your Water

Not all filters are created equal. In fact:

• Standard carbon filters (like pitcher filters) do not remove fluoride.

• Reverse Osmosis systems are one of the most effective methods for reducing fluoride at the tap.

• Both our Standard and PLUS Filtration Systems are designed to reduce fluoride, along with other contaminants like PFAS, chlorine, and heavy metals.

The Bottom Line

Fluoride may have been added with good intentions, but science is showing us there can be serious downsides to daily exposure. Families shouldn’t have to choose between dental health and whole-body health.

At The Clean Water Company, we make it simple to take control. Our filtration systems give you peace of mind that your family is drinking cleaner and safer water every day.
