NCT ID NCT07761715

First seen Aug 12, 2026 · Last updated Aug 14, 2026 · Updated 2 times

Summary

This study compares a non-fluoride whitening toothpaste to a standard fluoride toothpaste to see which better removes surface stains from teeth. About 100 adults will brush with one of the two toothpastes at home for four weeks. Researchers will measure tooth color changes using a standard stain index to determine if the whitening toothpaste improves whiteness more than the control.
