First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This study tests whether using very cold water (around 2-3°C) to rinse the inside of a tooth during a root canal can lower pain afterward. The trial includes adults aged 20-40 with painful, infected lower molars. Participants are randomly assigned to receive either cold rinses throughout the procedure, a cold rinse only at the end, or standard room-temperature rinses. Pain levels are tracked for 72 hours after treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- cold saline and cold sodium hypochlorite solution
- What this could lead to
- If effective, this simple cold-water rinse during root canals could become a standard way to ease pain after the procedure.
- What could go wrong
- This is a small, early-stage trial with only 45 participants, so results may not apply to everyone. The cold rinse might not reduce pain more than standard methods.
