I am 18, I’ve had braces, and I now have a permanent retainer behind my teeth. I’ve been following Santiago for a while and have been doing “thumb pulling / 3D oral pushing” for about 3 months, and I wear a Reviv mouthguard. I’ve come to the conclusion that for better results, I probably need to have my retainer removed. Can someone (preferably Santiago 😊) confirm this? And what about the retainer on my lower teeth? And what should I tell my dentist? Thanks in advance!

I am 18 now. I had braces, but my teeth are still a little bit crooked. My maxilla is recessed and my bite doesn’t feel comfortable. I want to try thumb pulling to widen and bring my palate forward. I still have a fixed retainer behind my teeth from my orthodontist. Should I have it removed? Upper and lower?
