First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested a new toothpaste containing potassium nitrate and fluoride to see if it can help reverse very early tooth decay. 47 adults wore a dental appliance with artificial tooth samples for two weeks while using the test toothpaste, a reference toothpaste, or a control. The main goal was to measure how much the toothpaste helped re-harden the enamel, a sign of early cavity repair.

If it works, this toothpaste could help reverse very early cavities and strengthen enamel, reducing the need for fillings.
