Thumbpulling is a looksmaxxing method where you put both thumbs on the hard palate and pull outward, a little diagonal, so the maxilla takes load. Stay off the teeth. Most people copy a video, rip as hard as they can, and wonder why nothing happens except a sore bite. Sutures do not work like that. You hold a static pull first so the palate actually has a direction, then you cycle the same force instead of going heavier, and you do Suture Traction Therapy on the face before the thumbs go in.

What is thumbpulling?
People search what is thumbpulling after seeing someone with both thumbs in their mouth, elbows out, pulling the roof of the mouth. That is the move. The point is not the thumbs. The point is strain in the palatal vault and the sutures around the maxilla and zygoma. Do it on teeth, gum edges, or the soft palate and you are loading the wrong tissue. Two-word spelling is the same thing: thumb pulling.
I start everyone on static thumbpulling. A held pull gives the palate a direction. Cyclic thumbpulling is the second step, same peak force, load and unload, not a harder yank. I teach it that way because the suture papers reward the waveform, not how hard you can rip. Most public tutorials skip that and sell the rest.
Where the force goes
This photo is the position. Thumbs on the hard palate. Outward, a little diagonal. Teeth are off limits. Copying the photo and ripping is how people hurt a bite and then say thumbpulling is cope.

Cyclic thumbpulling vs static
Static is the foundation. Hold 20-30 seconds, outward and slightly diagonal, about 40-60% of a hard pull. Firm enough that the palate stretches. Light enough that the jaw stays unclenched, breathing stays nasal, and you can stop. Both sides even. If teeth hurt, the joint clicks or locks, one side takes over, or you have to brace your neck, you are too heavy or you drifted onto bone you should not be on.
Cyclic comes after the static hold is clean. Same peak force. Load, unload, load, unload. No bouncing. In growing rabbits, that cyclic pattern grew sutures more than a static hold at the same peak force (PMID 12619937). Cyclic tension and compression at 1 N, 8 Hz changed suture width, cell density, and osteoblast surface (PMID 18032124). Small oscillatory doses can speed sutural growth (PMID 12454093). So the upgrade is not pulling harder. It is repeating the force you already have.
Those are animal suture studies, not a human trial of TikTok thumbpulling. They still tell you how to practice. Bone cells read mechanical input through channels like PIEZO1/2 (PMID 34208464). Distraction at the zygomaticomaxillary suture recruited osteogenic progenitors in experimental work (PMID 38971766). That is the neighborhood a palatal pull is trying to talk to. It is not a promise that eight weeks of thumbs will rebuild an adult face.
Does thumbpulling work?
Does thumbpulling work? Honest answer: there is no randomized human trial of the Instagram version. What exists is sutural mechanobiology, and it is not empty. Cyclic load beat static load at the same peak force in growing rabbits. Adult facial bone still adds periosteal matrix, slower than puberty (PMID 5917324, PMID 2399958). Measure months. A weekend of ripping will not give you a surgical expander result. A clean session, repeated, with the tongue parked on the palate the rest of the day, is the actual bet.
Suture Traction Therapy before thumbpulling
Suture Traction Therapy is the face work you do before thumbpulling. The literature treats cranial suture traction as a structured protocol for facial asymmetry (PMID 35888588). In practice: zygomaticomaxillary and frontozygomatic first when midface or asymmetry is the issue, then the palate. Steady pull. Not a jerk. If you skip this, you dumped palatal load onto a face you never organized.
Order I actually run: warm up, take the clench out of the masseters, STT, static thumbpulling, cyclic thumbpulling, light nasal breathing on the rhythm, then tongue back on the palate. Full maps are in the Craniofacial Mechanobiology Atlas. Hormones and food sit in how to improve facial dimorphism.
Thumbpulling vs mewing
Mewing is all-day tongue posture on the palate, lips closed, nasal breathing. Thumbpulling is a timed traction session. They are not the same, and one does not replace the other. After you take your thumbs out, the tongue has to hold the palate or the session dies into mouth-breathing posture. Hard mewing, meaning you crush the palate with the tongue all day, is not cyclic thumbpulling. Different tool, different dose.
Bruce vs Oscar Patel on thumbpulling
Oscar Patel (@oscarpatel) got thumbpulling in front of a lot of people. That part is real. The public version is still thumbs in, pull, paywall. Static vs cyclic, Suture Traction Therapy first, force on bone not teeth, the PMIDs: missing or gated. A lot of people copied the clip, loaded their enamel, and think that is the method. It is not.
I publish the order because the papers are public. Bruce (@bruceisprimal): STT, static thumbpulling, cyclic thumbpulling, nasal rhythm, myofunction after. You do not start on rhythm. You hold a clean static field first. If the useful half of the protocol is behind a course and the free half is a yank, that is gatekeeping. The better version is the one with citations, on this page.
How to do thumbpulling
Warm first. Palate only. Static until it is even. Then cycle.
- Warm-up. Hot shower or bath.
- Masseter release. Get the clench out before you load sutures.
- Suture Traction Therapy. Zygomaticomaxillary and frontozygomatic first if midface or asymmetry is the issue (PMID 35888588).
- Static thumbpulling, middle palate. Outward / slightly diagonal. About 30 seconds, release, one nasal breath, 4-6 holds.
- Static thumbpulling, anterior hard palate. Around the incisive papilla. Not on the incisors.
- Cyclic thumbpulling. Same peak force as the static hold. Load, unload. No bounce.
- Nasal breathing. Mouth closed, light. Match the pull to the breath.
- Tongue after. Palate suction, posterior tongue up. Rest of the day: tongue on the palate, lips closed, jaw unclenched.
What this will and will not do
Keep force on the hard palate. Stop for pain, click, lock, numbness, or a bite that suddenly feels wrong. This is how the mechanics work, not a medical treatment, not a guarantee of adult maxillary expansion.
The protocol, short
Thumbpulling is a palatal pull, not a tooth pull. Hold it static, then cycle the same force. Do Suture Traction Therapy first. That is the version that matches the suture papers, and it is the version I teach. Oscar Patel made the word famous. He did not put this order, or these PMIDs, in front of people for free. If you want the rest of the stack, use how to improve facial dimorphism and the atlas.
Frequently Asked Questions
Thumbpulling is a looksmaxxing technique: both thumbs on the hard palate, force off the teeth, pulling outward and slightly diagonal to load the maxilla and surrounding sutures. Same thing as thumb pulling.
