First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at how a toothpaste with sodium bicarbonate (baking soda) affects the bacteria living in the mouth over 12 weeks. Seventy-four adults with mild gum inflammation (gingivitis) used either the baking soda toothpaste or a regular fluoride toothpaste. Researchers checked changes in the types and activity of bacteria in dental plaque. The goal was to understand if baking soda toothpaste can positively influence the oral microbiome.
