Facts About Return on Investment of Oral Health Interventions

At a glance

Review the return on investment of oral health interventions in the United States.

Fast facts

In addition to promoting oral health, community water fluoridation and dental sealant programs also provide a positive return on investment.

Community Water Fluoridation

  • One year of providing fluoridated water in the United States is estimated to save $6.5 billion in averted direct and indirect dental treatment costs.1
  • Communities with fluoridated water save an average of $32 per person a year by avoiding treatment for cavities.1
  • The return on investment for community water fluoridation varies with size of the community, increasing as the community size increases, and saving costs even for small communities. Communities of 1,000 or more people see an average estimated return on investment of $20 for every $1 spent on water fluoridation.1

School Sealant Programs

  • Delivering dental sealants to children at high risk for cavities can be cost saving to Medicaid by averting more expensive treatment costs.2
  • School sealant programs that serve students at high risk for cavities can become cost saving in 2 years and save $11.70 per sealed tooth over 4 years.3
  • School sealant programs could save up to $300 million in averted costs by providing sealants to the 7 million children from low-income families who need them.3

Medical-Dental Integration

The health care system could save up to $100 million each year if dental offices performed screenings for diabetes, high blood pressure, and high cholesterol. Medical-dental integration between oral health and chronic disease prevention programs benefits patients and saves money.4
