Oral Health Program: Fluoridation for Health Care Professionals

Helping you and your patients understand fluoridation

Medical, dental, and public health experts recommend water fluoridation. Patients may ask physicians, pharmacists, dentists, nurses, and dental hygienists about fluoride and fluoridation.

As a trusted source of information for your patients, learn more about community water fluoridation basics and use the following evidence-based resources to help you share information. As a professional, you know that local public health, community leaders, and patients are relying on you to share the oral health benefits of water fluoridation.

On this webpage you will find resources and information to get your conversation started.

Research

Water fluoridation has been researched and studied for 80 years. National and international panels of experts in various health and scientific disciplines complete reviews of new and updated peer-reviewed scientific literature that use carefully designed methods to critically examine evidence. Recommendations are made based on findings across the entire body of scientific evidence rather than one study alone due to study designs and limitations.

Review the following resources to find information on fluoridation.

  • FLUID Fluoride Legislative User Information Database: Comprehensive database containing legal decisions by U.S. courts and current information on federal, state and local policies regarding community water fluoridation.
  • Fluoride Science: Fluoride Science reviews fluoride studies for professional communities that may engage in patient care and public health services.
  • Fluoridate Concentration Recommendation, U.S. Public Health Service: Read about the U.S. Public Health Service's fluoridation recommendation.
  • Scientific Statement on Community Water Fluoridation, CDC (Centers for Disease Control and Prevention): Read the CDC's scientific statement and recommendations regarding water fluoridation.

Trainings

  • Community Water Fluoridation 101 (Log in required) DHS training: Course covering the topic of community water fluoridation (CWF). The course will provide attendees examples of the type of myths spread by those opposed to CWF and how to respond. As a foundation to understanding these myths, the course will also provide basic information on the science behind fluoridation, how it works and why it works to prevent tooth decay. The objective of this course is to educate members of the oral health workforce (dental professionals, medical professionals, public health professionals, and water operators and engineers) on the evidence and science of CWF. Additionally, The Wisconsin Oral Health Coalition will offer one dental CE for Wisconsin dental providers completing the course.
  • Community Water Fluoridation: How Dental Professionals Can Lead the Conversation CareQuest training: Course covering how to communicate confidently and address any questions patients may have about water fluoridation.
  • Fluoridation Learning Online (FLO) CDC training: A free resource designed to build the capability of state fluoridation programs, and to help increase knowledge and refine skills to implement and maintain community water fluoridation. FLO covers the science, history, management, and technical information of water fluoridation.
  • National Oral Health Curriculum, Smiles for Life: Complete the comprehensive oral health curriculum to better understand oral health.

Fluoride varnish is a protective coating painted on teeth to prevent, slow down, or stop tooth decay. It's a safe, and effective treatment applied to all teeth. A medical or dental professional can provide this safe and effective treatment. Depending on how likely a person is to get a cavity, fluoride varnish may be applied two to four times per year. Fluoride varnish is used along other things that prevent cavities, including regularly brushing, flossing, using fluoridated toothpaste, and eating healthy foods. 

Resources are available for providers interested in helping meet their patient's oral health needs. The materials needed to apply fluoride varnish are readily available from medical and dental supply companies. The American Academy of Pediatrics provides resources for help with getting paid for oral health services. Wisconsin Medicaid’s policy (PDF) outlines billing practices for medical professionals, such as physicians, nurses, and physician assistants as well as dental professionals

Fluoride Supplementation, P-44531 (PDF)is the process of prescribing fluoride supplements in dietary forms to reduce dental caries in children at high risk for tooth decay and whose primary drinking water has a low fluoride concentration. The below process outlines necessary considerations for fluoride supplementation.

Assess the patient's fluoride intake

It's important to start by assessing a patient's fluoride intake. This allows you to understand where a patient may or may not be receiving fluoride before prescribing any supplements. 

  • Residential water: Determine the fluoridation level of the patient’s drinking water.
  • School and day care water: Determine how much fluoride is in the school or day care drinking water.
  • Bottled water: Determine if the patient drinks fluoridated bottled water. Most bottled water contains insignificant amounts of fluoride, but some brands have levels of fluoride that could be at or near recommended amounts. If it’s not listed on the label, contact the manufacturer to ask about the fluoride content.
  • Breast milk or infant formula: Determine the level of fluoridation the infant is receiving.
    • Breast milk has very low levels of fluoride.
    • Concentrated formula (powdered and liquid) contains varying levels of fluoride depending on the water it’s mixed with.
    • Ready-to-feed formulas contain very low levels of fluoride.

Determine the patient's caries risk level

Perform a caries risk assessment to determine a patient’s risk of developing caries. Follow the American Academy of Pediatrics' Oral Health Risk Assessment Tool for guidance.

When do I start or end prescribing fluoride supplements?

  • Start: Fluoride supplementation starts at about 6 months or as soon as their fluoride intake is determined insufficient.
  • End: Fluoride supplementation should end by age 16.

Dietary fluoride supplements

  • Fluoride drops
  • Fluoride tablets or lozenges

Fluoride supplement prescriptions should be reviewed and adjusted accordingly

Fluoride supplement dosing may change:

  • If an infant in a fluoridated area consumes anything in addition to breast milk.
  • If an infant in a fluoridated area consumes anything in addition to "ready-to-feed" formula.
  • When a child reaches age 3 and again when they reach age 6.
  • If there is a change in the source of the child's drinking water.

Use the following resources to help guide your conversations with patients and find valuable resources to share with patients.

  • Oral Health Practice Tools Helps primary care providers incorporate oral health into practice with these easy-to-use tools and downloadable resources. Learn how to perform an oral health risk assessment, provide nutrition and oral hygiene counseling, and to apply fluoride varnish as vital components of well-child exams. Starting with the Oral Health Prevention Primer can help!
  • Oral Health Toolkit for Primary Care Practice The integration of oral health into primary care practice is essential to improving oral health and overall health outcomes across the lifespan. For too long, oral health has been separated from the rest of the body, making it difficult for many populations and communities to access necessary preventive and emergent oral care. Developed through a collaboration (PDF) between the Hawai'i State Department of Health, Family Health Services Division, and the UH Mānoa Nancy Atmosphera-Walch School of Nursing, this toolkit contains valuable resources for integrating oral health into your primary care practice.
