The first set sent to me did not fit well. I have two missing teeth on top. When I put them in in they were hitting my bottom teeth. I figured I’d wear them a few days to adjust before replying. The very next day, to my surprise, a second top set showed up!? They were made slightly different and fit great! They look great also. They are whiter than my bottom natural teeth but that’s ok because I have whitening solution for the bottom. I purchased the classic in the BL1. They are very white so be careful when ordering just top or bottom. They look pretty real considering they match the general shape of my real teeth. I don’t like to eat with them in. It just doesn’t feel right. I may get used to it, I don’t know. I had problems with my normal bridge and that is what led me to try these. I would recommend these as an excellent option but I still believe that implants are the best solution other than the cost.
