Cavity is a permanent area of damage on the hard surface of your tooth that develops into a tiny opening or hole. It is caused by a process called demineralization, where acids produced by bacteria strip away the essential minerals from your tooth’s structure.

We now view caries as an ecological imbalance in the mouth. It’s not just about sugar; it’s about your oral microbiome becoming too acidic for your teeth to handle.

If it is in Stage 1 (White Spots), yes! With the right minerals and hygiene, your tooth can heal itself. Once it becomes a physical hole, however, you need a dentist.

Technically, yes.

The bacteria that cause cavities (Streptococcus mutans) can be passed through saliva, which is why sharing spoons or kissing can transfer decay-causing germs.
