5. Beer & Wine We don’t want to be killjoys but beer and wine are very acidic. The pH of beer is around 3.7-4.1 whilst wine tends to be worse, around the 3.5pH mark. With sugar in both, this acid has a very detrimental effect indeed. It isn’t really acceptable to drink alcohol through a straw so the best way to counteract the damaging effects of booze on your teeth is to brush regularly. If you are planning a night out of drinking spirits, brush your teeth beforehand to create a barrier between the wine and your pearly whites.
