3/7/2026

Summary

Story summary

The National Institutes of Health are studying the oral microbiome, identifying about 700 microbial species and noting some may contribute to cancer and Alzheimer's.
Researchers aim to determine how changes in these microbial populations affect health.
They are developing targeted medications to eliminate harmful bacteria while preserving beneficial ones.
Current supplements for oral health lack proven effectiveness, and researchers say the work is early but could lead to microbiome-based treatments.
