I am on my third Invisalign tray and I'm experiencing a lot of pain on the rigjht side of my face and jaw. When I wear the tray for more than 22 hours for 3-4 days, the pain feels a lot like I had my impacted tooth removed. I can't wear it anymore. My doctor says he has no idea about this pain. I must do something about it. Can any doctor here explain if this is normal? I want to stop this treament and get my money back.
