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

Summary

This study in Malawi tests whether chewing xylitol gum three times a day during pregnancy can improve gum health and change the bacteria in the mouth and vagina. Researchers will also check if it reduces pregnancy complications and affects babies' brain development. 80 pregnant women are participating, with half chewing xylitol gum and half chewing a similar gum without xylitol.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Xylitol gum
What this could lead to
If it works, this could point toward a simple, low-cost way to improve gum health and reduce pregnancy complications in regions with limited dental care.
What could go wrong
This is an early-phase study with only 80 participants, so results may not apply broadly. Chewing gum may not be enough to significantly change the microbiome or prevent complications.
