Community Water Fluoridation

en español

Community water fluoridation is safe and the most cost-effective way to deliver fluoride to everyone. On average, it costs only $0.64 per person to fluoridate water for a year. For most cities, every $1 invested in water fluoridation yields $38 savings in dental treatment costs (Fluoridation Facts American Dental Association [ADA]). Community water fluoridation is recommended by nearly all public health, medical, and dental organizations.

To know your water system's fluoridation status go to the CDC My Water's Fluoride webpage.


Community water fluoridation is one of the most practical, cost-effective, equitable, and safe measures communities can take to prevent tooth decay and improve oral health.–Dr. Vivek H. Murthy, U.S. Surgeon General (2014-2017, 2021-Present)

Texas State FlagFluoridation in Texas

Approximately 105 public water systems, serving 9.7 million people, adjust the fluoride level in the drinking water. Some areas of the state have naturally occurring fluoride. A little over 19.6 million people (72% of the population) drink adjusted or naturally occurring fluoride.

In 1946, the City of Marshall became the first city in Texas and one of the first three cities in the United States to implement community water fluoridation. For over 70 years, the addition of fluoride to the drinking water has benefited over 66% of the U.S. population.


Frequently Asked Questions

What is community water fluoridation?

Community water fluoridation is the adjustment of fluoride to the drinking water at an optimal level for the reduction in tooth decay.

Is community water fluoridation safe?

Community water fluoridation is safe and the most cost-effective way to deliver fluoride to everyone.

How do Texans benefit from water fluoridation?

Water fluoridation strengthens the tooth enamel. Teeth begin forming before birth and continue to form and grow until the teen years. People consuming water containing adequate fluoride during this period have stronger tooth enamel, which is resistant to tooth decay. It also helps adults by coating their teeth while they drink the water.

Why is it important we prevent tooth decay?

Children with poor oral health are three times more likely to miss school due to dental pain. Poor oral health can affect your heart and increase your risk of Alzheimer's disease.

How do I know if my water system is adding fluoride?

To find out if your water system adds fluoride, visit the CDC My Water's Fluoride webpage. You should follow up with your water system to verify the information is correct.

Is fluoride naturally in the water?

Some areas of the state have naturally occurring fluoride in their water. Not all water has the optimal amount of fluoride in the water to help reduce tooth decay. When the fluoride level is low, we add fluoride to the drinking water to help prevent tooth decay.

What does community water fluoridation cost?

On average, it costs about $0.64 per person to fluoridate water for a year. For most cities, every $1 invested in water fluoridation yields $38 savings in dental treatment costs.
