Summary

This study tested a whitening toothpaste against a regular toothpaste to see if it could remove surface stains from teeth. 118 adults brushed twice daily for six weeks. Researchers measured stain levels at the start and after 7, 14, 28, and 42 days. The goal was to see if the whitening toothpaste worked better than the control.
