Just one alcoholic drink a day impacts oral health

Researchers looking at the effects of alcohol on oral health discovered drinking habits influence the types of bacteria that reside the mouth, with higher numbers of so-called ‘bad bacteria’ found in those who consume alcohol daily.

Scientists tested saliva samples from more than 1,000 adults and found that, compared to non-drinkers, those who had one or more alcoholic drinks per day saw a reduction of healthy bacteria in the mouth, with a significant increase of harmful bacteria also detected.

Such changes could contribute to alcohol-related diseases, such as gum disease, tooth decay, head and neck cancer, and digestive tract cancers.

The Oral Health Foundation wants to raise awareness about the dangers of alcohol and the impact that regular consumption can have on the mouth and overall health.
