I’m looking for a way to remove this stain that I have from a filling that I had. I went to the dentist for my regular cleaning and she said it wasn’t decay or anything, my tooth is just stained. I’ve been using whitening strips but it still doesn’t look very good.I’m hoping I can find something since it’s something I’m insecure about now. Please leave me some tips or anything to help me with this! Thank you!
