How your favourite tipple could be changing the bacteria in your mouth… and it’s not good news!


Just one alcoholic drink a day changes the balance of bacteria in the mouth and can lead to a range of diseases from tooth decay to cancer, a new study has revealed.

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.

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.

The study also found the type of alcohol consumed also affects for the type bacteria in the mouth, with researchers testing wine, beers and spirits.

They found that wine drinkers produce more bacteria responsible for periodontal disease when compared to non-drinkers while those who consume beer produce an increase in bacteria that are linked to caries.
