Drinking too much can alter the bacteria in your mouth

People who consume large quantities of alcohol are additionally more likely to risk everything from gingivitis to even certain types of cancer, compared to those who don't drink.
The study observed 1,044 American adults, 270 of whom didn't drink at all, 614 of whom drank moderately, and 160 of whom drank heavily (defined as more than two drinks a day for men, and more than one drink a day for women). Drinkers had higher levels of three strains of bacteria that cause diseases "including cancers of the head, neck, esophagus, and pancreas," Time explained.
