Description
Erandis Dheni Torres Sánchez and co-authors present a 2026 narrative review of Helicobacter pylori at the crossroads of mouth and stomach disease. The bacterium drives ulcers, chronic gastritis, and gastric cancer. Evidence increasingly suggests it also shelters in dental plaque and periodontal tissue, forming a reservoir outside the stomach that standard treatment never reaches.
The review describes how the organism might survive the oral environment and what that presence means clinically. The authors propose traffic in both directions: periodontitis fuels body-wide inflammation that may encourage stomach infection, while an oral reservoir can reseed the stomach after eradication therapy and cause relapse. They suggest that clearing the bacterium from the mouth could become part of preventing gastric reinfection, and point to metagenomics and proteomics as tools to test the idea properly.
