I'm on my 9th day, using my 1st aligner. From the beginning the aligner on my lower teeth had a bad fit. It fits firmly on my premolars/molars but about 3-5 mm above my lateral and central incisors. In order to fit it; the lower tray has a jagged edge on the inside and is ''warped''. My teeth have moved in the wrong direction I think. My major concern is that tray #2 will NOT fit on my lower teeth at all, which did at first. Could this be due to a bad teeth impression or aligner print out ?
