Scientists discover that bacteria in the mouth is determined by nurture, not nature

Scientists discover that bacteria in the mouth is determined by nurture, not nature  When it comes to dental health, individuals can't fully understand what's happening with your teeth and gums without considering bacteria. The mouth is teeming with different types of bacteria, some good and some bad. When people don't practice proper oral care techniques, that bacteria is allowed to grow unchecked, and can cause serious issues to both your dental health and overall well-being.

Recently, researchers from the University of Colorado sequenced the microbial DNA present in numerous saliva samples of twins to learn more about the bacteria in the mouth. They wanted to determine if either your genes or the environment plays a significant role in what types of bacteria are found in your mouth.

What the scientists discovered was that the mouth bacteria of twins became less similar when they moved away from each other. This suggests that environment has a larger effect on mouth bacteria than genes. This could have large implications for dental health.

"We can now better understand how oral hygiene, environmental exposure to substances like alcohol, methamphetamines and even foods we eat affect the balance of microbes," said researcher Ken Krauter, Ph.D.
