Brush then floss, or floss then brush? a trial puts the order to the test.
NCT ID NCT07737626
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This trial asks whether the sequence of powered toothbrushing and dental flossing changes how much dental plaque is removed. Forty-six healthy adults will try both orders — brushing then flossing, and flossing then brushing — with a 15-day break in between. Plaque levels are measured before and after each routine to see if one order cleans better.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- powered toothbrushing and dental flossing
- What this could lead to
- If one sequence clearly removes more plaque, it could give people a simple, no-cost way to improve their daily oral hygiene.
- What could go wrong
- This is a small, short-term trial in healthy young adults, so results may not apply to everyone. The difference between sequences may be too small to matter in real life.
