Is it possible for small cavities to disappear?

I had these two really tiny cavities and my first molars on both my left and right side. They were really small ones and I talked to my dentist long ago about them. She said they weren't a big deal and that if I maintained good oral hygiene, I shouldn't expect them to get bigger. Anyway, every night I floss and for the past few days I've noticed that one of the cavities (on my right first molar) has disappeared. It's gone and the one on my left seems to be getting smaller.

I haven't been to dentist in two months. Is this possible that tiny cavities can just disappear like this?

If the incipient decay is limited to just the enamel, it can indeed re-mineralize if you maintain good oral hygiene.

However, if the decay has already penetrated the enamel and into the dentin, it will require a dentist to drill out the decay and fill the tooth.

In your next checkup (4 months from now), the dentist should take a bitewing X-ray to make sure there is no decay in the dentin. If there is none, you are in good shape.
