Summary

This study will test a 16% carbamide peroxide gel used at home in custom trays for 90 minutes daily over six weeks. Ten adults with healthy gums and no prior whitening will have their tooth color measured by a special device and report how their quality of life changes. The goal is to see if this simple whitening routine effectively lightens teeth and boosts well-being.

What this could mean

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

Active substance
Carbamide peroxide 16% gel
What this could lead to
If successful, this could confirm an effective at-home whitening method that improves both tooth color and quality of life.
What could go wrong
This is a very small study (10 people) with no control group, so results may not apply to everyone. Tooth sensitivity or gum irritation are possible side effects.
