A new study revealed that drinking alcohol excessively promotes the growth of microbes in our mouth. The study was published in the journal Microbiome.
Researchers found that heavy drinking influences the microbial composition of oral cavity negatively. Drinkers have mouths filled with bad bacteria, such as Actinomyces, bacteroidales, and Neisseria. The number of good bacteria like Lactobacillales will get reduced in number. Lactobacillales are found in pro-biotic food items and help to prevent problems of the digestive tract.
Jiyoung Ahn, the lead author and epidemiologist of the study said that their study gives clear indication that drinking causes imbalance in the number of healthy microbes and this will help in explaining why drinking is linked to chronic diseases and cancer. The study was conducted by the New York University School of medicine, took four years to complete. Thousands of Americans who drank liquor, wine or beer was included in the study. Earlier one study revealed that one in six Americans drink excessively at least once in a week.
According to the authors of the study, this is the first study conducted linking consumption of alcohol and oral health. Experts feel that more study is needed to confirm whether drinking alcohol truly impacts the oral health.
