Toothpaste Targets Gum-Disease Bacteria Without Killing Beneficial Microbes

Fraunhofer researchers identified a compound—guanidinoethylbenzylamino imidazopyridine acetate—that blocks growth of periodontitis-causing bacteria like Porphyromonas gingivalis without killing beneficial oral microbes, enabling PerioTrap to develop a toothpaste that helps prevent gum disease while preserving the oral microbiome; the project followed GLP standards and also produced a post-cleaning gel, with future products (mouthwash, veterinary uses) in development.
