School Fluoride Program

Multnomah County Health Department offers a school-based fluoride tablet program in an effort to provide fluoride supplements to children across the county. Participation by school or district is voluntary.

The Health Department supports fluoride as an evidence-based practice for preventing tooth decay. Fluoride levels in our water supply are not currently at a level that is beneficial to reduce tooth decay. Currently, no water systems add fluoride to the water in Multnomah County.

Fluoride tablet programs are used in communities where the water is not fluoridated so that children can still benefit from the use of fluoride. If our water is fluoridated at some time in the future, there will be no need for a fluoride supplement program at school.

For Schools

  • The Health Department provides training and materials to school personnel.
  • We provide fluoride tablets at no cost to the school.


All public and private schools serving children ages 3 through 5th grade are eligible to participate. The program is currently offered in seven school districts and more than 108 schools in the county. We provided tablets to more than 29,000 children last year.

For Parents

  • Participation in the fluoride program is voluntary.
  • You must return a signed permission slip to your school for your child to participate.
  • Your child should only take fluoride drops or tablets once per day, either at school or at home.
  • Fluoride is safe and will help your child build healthy teeth.
  • It's important to brush your child’s teeth twice each day at home.
