First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a toothpaste with stannous fluoride against a regular fluoride toothpaste to see which controls bad breath longer. 80 adults in Thailand brushed twice daily for 3 weeks, then had their breath scored by judges 12 hours after overnight brushing. The goal was to see if the new toothpaste keeps breath fresher for longer.

- What this could lead to
