Even with consistent brushing and flossing, some people develop more cavities than others — a difference that may be partly explained by genetics and the make-up of microbes in the mouth, according to a new study based on the largest collection of oral microbiome profiles to date. The study, led by scientists at the Broad … Read more

Microbiome Study: Gum Disease-Causing Bacteria Borrow Growth Molecules From Neighbors to Thrive

The human body is filled with friendly bacteria. However, some of these microorganisms, such as Veillonella parvula, may be too nice. These peaceful bacteria engage in a one-sided relationship with pathogen Porphyromonas gingivalis, helping the germ multiply and cause gum disease, according to a new University at Buffalo-led study. The research sought to understand how … Read more

Alcoholic Drinks Linked to Harmful Oral Bacteria

When compared with nondrinkers, men and women who had one or more alcoholic drinks per day had an overabundance of oral bacteria linked to gum disease, some cancers, and heart disease. By contrast, drinkers had fewer bacteria known to check the growth of other, harmful germs. These are the main findings of a study published … Read more
