I had a dentist appointment today to have a filling done.
The dentist asked if I drank a lot of cafinated drinks, he thinks the acid in the drinks may have caused some decalcification which led to a cavity.

Is caffeine acidic or are the drinks that contain caffeine just happen to usually contain acid?

Caffeine is quite surprisingly basic. Coffee on the other hand, is acidic with a pH of around 5.0.   Caffeine also stimulates the nervous system which can cause an acidicty increase in your stomach, but that should be of irrelevant to your teeth unless you accidentally swallow them []

Coca Cola and other soft drinks contains some nasty acids and are therefore more likely to decalcify your teeth. Beer is included to that group and so are juices.

Thanks Doc.
I had a small cavity, no real danger of swallowing my teeth just yet.

No problem.

Cavities happen []  But as long as we brush our teeth, the damage is limited.
