NCT ID NCT06035588
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether using a 16% carbamide peroxide whitening gel every other day causes less tooth sensitivity than using it every day. 110 adults with healthy teeth applied the gel for two hours over three weeks. The goal was to see if alternating days reduces pain while still whitening teeth effectively.

- What this could lead to
- If successful, this could offer a way to whiten teeth with less pain, making the process more comfortable for patients.

- This is a small, completed study with 110 participants, so results may not apply to everyone. The gel still causes some sensitivity, and whitening might be less effective with alternate-day use.
