They are not cavities. I always get them like a few months after my visit to the dentist. When he cleans my teeth, the spots just come off very easily. But a few months later, they come back. He just told me to brush my teeth more. It's been like this for years!
Anyways, they're back, and I'm brushing so hard... but they STILL won't come off! Aghh! Help?
