An early stage cavity is usually a tiny, non cavitated enamel lesion (often a white spot). Minerals have started to leach out, but there is no hole yet.
Remineralize means you are helping enamel rebuild mineral content, mainly calcium and phosphate, so that weak spot can harden and behave more like normal enamel again.
If you put toothpaste on your floss, it gets fluoride right between the teeth, where these early lesions often start, helping weakened enamel pull minerals back in and resist acid better.
So does it go away? At the early stage, it can stop and even reverse because the enamel surface is still intact. If there is already a hole, remineralization cannot fill it, and you usually need a filling.
Add this trick to your oral health routine once a day, ideally at night. ✅
