I had 22 top and 22 bottom trays. I finished them. Lasted about 11 months. I wore the trays at least 21 hours everyday. But my teeth are not aligned properly . It's a discomfort when I close my mouth without the tray on. my dentist told me I will have refinement trays. 3 weeks later, he gave me the first refinement tray and told me I got 16 refinement trays which means 8 months more.He didn't show me any videos or anything. I'm not sure where the treatment is going. Can I go reverse using the same trays and get my teeth back to the original position as they were before the treatment?
