New toothpaste aims to zap tooth pain fast

This study tested whether a special toothpaste with 8% arginine (CSPR) can reduce tooth sensitivity better than a regular Colgate toothpaste. 95 adults with sensitive teeth used the toothpaste for 8 weeks. Researchers measured sensitivity using a gentle touch test and a cold air blast. The goal was to see if the arginine toothpaste provides faster and longer-lasting relief.
