Fluoride varnish has been shown to be effective in preventing dental caries. This webpage is devoted to providing dental teams and our medical and community partners with information about fluoride varnish, including literature that provides evidence of its effectiveness. There is also a link to the online course, which provides instruction in the application of fluoride varnish, available to all involved in the IHS ECC Collaborative.
One study showed a 44% reduction in caries incidence in 3-yr. olds.

The application of fluoride varnish has been proven to be an effective method of reducing early childhood caries by protecting teeth, re-mineralizing weakened tooth enamel and slowing or halting the progression of early decay.
