Summary
This study tested whether a toothpaste with NovaMin (Sensodyne Repair and Protect) can reduce tooth sensitivity during and after teeth bleaching. 90 adults used either the test toothpaste, a standard fluoride toothpaste, or another sensitivity toothpaste. Participants rated their sensitivity daily. The goal was to see if the test toothpaste works better than the others for comfort during whitening.
