A toothpaste that specifically thwarts periodontitis

Periodontitis is a widespread disease with far-reaching health consequences. Researchers at the Fraunhofer Institute for Cell Therapy and Immunology have now developed an approach that could fundamentally change oral care. Instead of destroying all bacteria with a "chemical club" as was previously the case, the new technology relies on precision. A special substance specifically blocks the germs that trigger inflammation of the gums, while the healthy microorganisms remain unaffected.

The decisive advantage lies in maintaining the natural balance of the oral flora. While conventional mouthwashes kill pathogens but destabilise the microbiome, the new active ingredient merely slows down the growth of harmful bacteria. These lose their pathogenic effect so that healthy germs regain the upper hand. The research has now resulted in a marketable product. The spin-off PerioTrap has transferred the technology into a toothpaste and a care gel that can be used both in everyday life and in the dental practice. Developed under strict quality standards and accompanied by material science tests, the product represents a gentle but effective approach to one of the most common chronic diseases. A small innovation with great potential for healthy teeth and gums.
