Warm fillings may soothe sensitive teeth — a trial puts it to the test

NCT ID NCT07720999

First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time

Summary

This trial tests whether warming up dental filling materials before placement can reduce inflammation inside the tooth and lessen pain after treatment. Thirty adults with deep cavities will receive fillings at different temperatures — one group gets a special flowable composite preheated to 65°C, another gets a standard composite warmed to 55°C, and a control group gets the same standard composite at room temperature. Researchers will measure markers of inflammation in fluid from the gums and ask participants about pain levels over a week.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
preheated dental filling materials (VisCalor thermoviscous bulk-fill composite at 65°C; Tetric EvoCeram conventional nanohybrid composite at 55°C or room temperature)
What this could lead to
If preheating reduces inflammation, dentists may adopt warmer fillings to lessen post-filling pain.
What could go wrong
This is a very small early trial with only 30 participants, so results may not apply broadly. Preheating could also cause other issues not measured here.
