Can fluoride toothpaste reverse cavities?

It can only reverse very early, microscopic enamel decay. Once there is an actual physical hole, you have to go to a dentist for a filling.

In my personal experience, fluoride toothpaste only helped when my dentist told me I had very minor, early enamel wear. It didn't do anything for my actual cavity, which ultimately had to be filled. I can't speak for everyone, but for me, a dental visit was the only real solution.

I always go to a reputed dental clinic in my city for any tooth issues, as they have the best diagnostic tools. My dentist clearly explained that toothpaste can only remineralize the surface level; it cannot repair a cavity that has penetrated deep. Ask your doctor directly during your next checkup so they can take an X-ray and guide you.

Dealing with PCOS already makes me so careful about my overall health and inflammation levels, including oral hygiene. From what I understand, fluoride toothpaste is great for strengthening weak enamel, but it's hard to say if it can cure an active cavity. I always prefer to get a professional opinion from my dentist rather than guessing.

Yes, it only works on incipient decay before a cavity fully develops. Regular brushing with a good fluoride toothpaste is a great preventive measure, but see a doctor if you feel pain.
