When I had my baby/milk teeth, I had fillings in every one of the munching ones, not the biting ones. The dentist told me some things and showed me some pictures, and now I have no fillings. My front tooth is technically a filling though. I face planted a curb when I was younger and snapped my tooth, so the dentist made a bit to stick on out of filling, they said I may need it crowning at some point, but I cba, I've only had it replaced once, and that was because I nutted my handlebars and knocked the filling bit off.
