Thanks Lisa! That's what I was hoping someone would say.

Small cavities can be reversed through good oral hygiene. Enamel
can indeed grow back from a small degradation. A good dentist will
not fill every cavity as soon as it shows up on an x-ray. I haven't
had a new cavity that needed to be filled in almost 20 years.
