New toothpastes aim to whiten teeth and soothe sensitivity
NCT ID NCT07297732
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two experimental toothpastes containing potassium nitrate to see if they can whiten teeth and reduce dentin hypersensitivity (tooth sensitivity). 254 adults with sensitive teeth used one of the toothpastes or a regular fluoride toothpaste for 8 weeks. Researchers measured tooth color and stain levels, as well as sensitivity to air puffs. The goal is to find a toothpaste that both whitens and eases discomfort.
