Keeping bad bacteria at bay

At-home health tests, such as those for detecting pregnancy, have been around since the 1970s. But, the Covid-19 pandemic introduced an even wider audience to the concept and took it to a whole new level. Researchers at the University of Cincinnati have created a device that can diagnose gingivitis. Its lateral flow assay picks up on the presence of the specific bacteria in saliva that causes the disease.

As you know, the mouth is colonised by 200 to 300 bacterial species, but only a limited number of them lead to dental decay or periodontal disease. Some of the most common include:

Bacteria such as Porphyromonas gingivalis and Treponema denticola are anaerobic and produce toxins that cause inflammation of the gums when they multiply. They can infiltrate the areas around the gum line, eventually leading to a breaking down of the connective tissue and bone surrounding the teeth. Given that bacteria collect throughout the mouth, especially on the teeth and gums, every time food or drink is consumed (other than water), diet can play a significant role in helping to prevent and manage gingival disease. Indeed, a diet rich in vitamins and minerals is essential for healthy gingiva.
