Summary

This study tests if a probiotic spray containing good bacteria can help prevent and treat gum disease in older adults. Researchers will give 90 elderly participants either the probiotic spray or a placebo for four weeks. They will measure changes in gum health, bleeding, and bad breath to see if the spray is safe and effective.
