What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Fluoride-containing varnish and fluoride-free placebo varnish
What this could lead to
If it works, this could point toward a more effective way to relieve tooth sensitivity using a simple varnish.
What could go wrong
This is a small, early-stage trial with only 66 people. The fluoride-free varnish is a placebo, so the real benefit may be small or temporary.
