Periodontitis is a common condition that can affect much more than just oral health. Scientists at Fraunhofer have discovered a compound that specifically blocks the bacteria responsible for this disease while leaving the rest of the oral microbiome intact. This innovation has since been developed into a range of oral care products by the spin-off company PerioTrap.

The human mouth contains more than 700 types of bacteria, but only a small number are linked to periodontitis. These harmful microbes collect in dental plaque, especially along the gum line, where they can trigger inflammation (gingivitis). If left untreated, this inflammation can progress into chronic periodontitis, leading to gum recession and tooth loss.
