3 weeks of thumbupulling. Expanded my palete for 1mm. I do thumbpulling usually 2 hours per day

hi, i started thumbpulling like in november 2025, right now i'm losing hope because My palate didnt expand, why? still 35mm palate

Measured on first pre molar. Started out as 29.8-30 1.5 weeks later Consistent 31 mm

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?

I get it that some people have issues with high-intensity thumbpulling with chin-tucks, but isn't that simply because, they should start with lower intensity and only after some time the body will adapt to higher intensity? The rationale is similar to reviv mouthguard. A person who's super recessed shouldn't immediately try to wear reviv XL for 12 hours a day, but should start with wearing a smaller mouthguard for less time. Personally, I've been doing high-intesity thumbpulling with chin-tucks once a day 4 sets for each third of the palatte for 4 months now and I've gotten massive results. Also, it takes me literally 5 minutes a day, so that's great stuff.
