Summary

This study tested whether a toothpaste with stannous fluoride is better at reducing bad breath than a standard fluoride toothpaste. 49 adults with halitosis brushed twice daily with each toothpaste in separate periods. Trained judges rated their breath odor at several time points. The goal was to see if the stannous fluoride formula provides better breath freshening.
