Cavities ...

How can you have cavities but there aren't any holes in your teeth?

Dental caries doesn't always start from the occlusal aspect. Any inter-dental food lodging can cause caries to start or enter the tooth from the proximal side. You normally do not notice it until the tooth fractures or aches on a day.

Also,there are dentinal caries,which travels the opposite of enamel caries.
