New Study Shows Normal Bacteria Could Be Catalyst for Gum Disease

New research conducted by Queen Mary University of London has given an interesting insight into the way normal bacteria affect the development of gum disease, and could lead to new preventative measures being developed through manipulating these bacteria to help protect the gums.

The study was conducted on mice living in two separate test conditions. One set of mice had normal bacteria in their mouths, while the other mice were raised to be free from bacteria. Small amounts of Porphyromonas gingivalis, a bacteria commonly found in the oral cavity, was introduced to both sets of mice. The mice with normal bacteria in their mouths subsequently developed periodontal bone loss, while those who had previously had bacteria free mouths remained free of the disease.

Scientists found that the presence of P. gingivalis stimulated the growth of normal bacteria, which had a major effect on the inflammatory and immune system of the mice. It appears that even a small amount of P. gingivalis can have an almost disproportionate influence on the severity of gum disease that develops. It now seems that periodontal disease develops when P. gingivalis interacts with existing bacteria, and that these existing bacteria are needed for this to occur.

These findings have led scientists to wonder if normal bacteria could eventually be manipulated to provide a protective effect in the mouth the same way probiotic yogurt is beneficial for the digestive system. Unfortunately, there is still quite a way to go before any product might appear on the market. For this idea to be viable, scientists need to discover the exact role played by normal bacteria in helping periodontal disease develop through its interaction with P. gingivalis, but it looks hopeful that this study may lead to more preventative measures being developed in the future.

This is encouraging news, but in the meantime people still need to pay attention to their daily oral hygiene routine, as gum disease remains one of the major causes of tooth loss. Brushing twice a day and flossing will at least help keep plaque build-up at bay, and everyone is urged to keep up with preventative measures such as visiting the dentist regularly, and having their teeth cleaned professionally. Dental hygienists and dentists are also great people to get advice from as to how to clean teeth more effectively. Other protective measures include eating healthily and avoiding smoking. According to the Department of Health’s 2007 report, 54% of the adult population in the UK suffers from some degree of gum disease.
