I had a small gap between my tooth and tray when I put my first tray in. I'm not on my 12th tray out of 14 and the gap has just got worse! I feel like the tooth hasn't moved at all, the attachments isn't in the right place anymore it's way higher than the little bubble it should be in. I mention it to my dentist every time I see her and she just says the tooths just got more room to move now. Is she right?? I thought it meant the tooth isn't tracking and I need refinement trays??
