You may know that alcohol abuse can have harmful effects on your brain, heart, liver, and other parts of your body, but did you know that it can also have an effect on your teeth. Alcohol increases your risk for tooth decay, and here are the reasons why.

High Sugar Content

Your mouth contains thousands of oral bacteria, and when these bacteria collect into a film on the surface of your teeth, then they are called plaque. Plaque causes tooth decay because it uses the sugars in foods to grow and create acids. These acids eat away at tooth enamel, eventually creating cavities. Alcohol has a very high sugar content, which will increase your risk for tooth decay.


Alcohol is very acidic, which increases your risk for tooth decay by attacking the enamel tissues that protects your teeth. These acids can also cause erosion, sensitivity, stains, and changes to the shape of your teeth.

Dry Mouth

People who frequently consume alcohol have drier mouths. This dryness increases your risk for tooth decay because saliva is your body’s natural defense against cavities. Saliva not only neutralizes the acids that attack tooth enamel, but it also brings in the minerals that rebuild and strengthen teeth.
