Dental Health Facts + Benefits of Fluoride

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.

Facts About Water Fluoridation

Approximately 100 communities in Missouri are currently supplementing the natural fluoride level in the water system to the optimum for dental decay prevention.

What is fluorosis?

Dental fluorosis is a condition that causes changes in the appearance of tooth enamel. It may result when children regularly consume fluoride during the teeth-forming years, age 8 and younger. Most dental fluorosis in the U.S. is very mild to mild, appearing as white spots on the tooth surface that may be barely noticeable and do not affect dental function. Moderate and severe forms of dental fluorosis, which are far less common, cause more extensive enamel changes. In the rare, severe form, pits may form in the teeth. The severe form hardly ever occurs in communities where the level of fluoride in water is less than 2 milligrams per liter.

Fluorosis is not a disease. The effect of fluorosis, in most cases, can only be determined by a dentist during an examination. Fluorosis in the United States will not effect tooth function and may make teeth more resistant to tooth decay.

My Water’s Fluoride

  • Visit Missouri's "My Water’s Fluoride" page to find out whether your local water system optimally fluoridates its water. For more specific information, contact your local water district.
  • The Missouri Department of Natural Resources maintains a website containing Consumer Confidence Reports on each community water supply in Missouri.

Fluoride Systems

  • Recommended Standards for Water Works
  • Fluoride Systems Design is covered in the courses offered through MOWRCC. For more information, see course information under Fluoridation Training.

Fluoride Notification Statute Information

Missouri Revised Statute 640.136 was signed by the Governor in June of 2016. This statute requires that any public water system or district must notify the Missouri Department of Natural Resources (DNR), Missouri Department of Health and Senior Services (DHSS), and its customers of its intentions to make modifications to fluoridation of its water supply.

  • To review the state law: Missouri Revised Statute 640.136.
  • A change in practices includes any addition or discontinuation of fluoridation.
  • The notification must take place at least 90 days prior to any vote or meeting where a change in fluoridation practices is decided.
