Why does coffee give you cavities?

Coffee itself is not acidic enough to cause cavities. The pH level of coffee is around 5, which is similar to the pH level of orange juice. The bacteria that cause cavities, Streptococcus mutans, thrive in an acidic environment with a pH level below 5.5.

However, coffee can contribute to cavities in other ways. Coffee can stain your teeth, making them more visible. Coffee can also dehydrate your mouth, reducing the production of saliva. Saliva helps to wash away food particles and bacteria from your teeth and helps to neutralize acids in your mouth. When your mouth is dry, bacteria have more time to produce acids that can attack your teeth.

You can help to prevent cavities by:

* Drinking coffee in moderation.

* Avoiding sugary coffee drinks.

* Drinking water after you drink coffee.

* Brushing your teeth twice a day with a soft-bristled toothbrush.

* Flossing your teeth once a day.
