Summary

This study tests whether a daily probiotic lozenge (SALI-10) can prevent gingivitis, a common gum disease that causes bleeding and inflammation. About 60 healthy adults will stop brushing for a short period to allow plaque buildup, then take either the probiotic or a placebo. The main goal is to see if the probiotic reduces gum bleeding compared to placebo.
