“Alot Pain at Jaw and Some at Gum ”

I noticed you are in Bangkok. Did you go see a dentist/ortho? What did they do exactly? If you have a doctor that says he doesn't know, I'd abort the treatment because it just doesn't sound right. Your doctor is the one who is suppose to answer your questions and is suppose to know what is going on. The 3rd set of trays is not suppose to hurt the way you're explaining (unless your gums are reallyyyyyyy sensitive I suppose) I don't think it's normal because your mouth is pretty adaptable. Did you have any jaw/facial pain before you started your treatment? If I were you, I'd go get the pain checked out. It can probably lead to some serious problems. Good luck and please update. I feel very bad for you :(

my dentist warned me when i started (I am on my 3rd tray) that if I experienced pain, not sensitivity, when i put my trays in or took them out, to let him know immediately, because that could be an indication that your teeth are trying to reposition but do not have enough room to move. He told me to come in if i did experience that and he would have to file some teeth to make room. Also, I have been using Flouride toothpaste at least twice daily, it really helps with sensitive teeth. Good luck!!!

I don’t think it’s completely abnormal to have some amount of pain and pressure on your teeth they are moving after all that’s the point. Every time a put a new tray in I feel pain and pressure for about 2or 3 days after and cant eat anything that’s hard. What you describing could be TMJ it’s not common but a possible side effect with Invisalign. If this treatment is not working I would see about getting any money back you may have spent.
