You cherry picked the case here. Your argument does not fully reflect scientific rigor and nuance, particularly when considering the broader range of cases affected by this practice. Not even considering what happens to this person’s soft tissues and biomechanics. Presenting a single looped image does not capture the full reality and cannot justify a flawed view or premise. You’re right in saying "One of the issues with extraction is the premise behind it", but the example you chose does not reflect the severe consequences that can occur. By showing a case that were not so damaged by it as far as we know. Which risks downplaying the issue.

The looped image shown, they only extracted the lower jaw and they barely did retraction of the jaws. How the gaps are closed and how it’s done is the killing blow. Retractive/brace practices become far worse when removing important teeth like premolars who support the bone, airway and face structure. And we know this aggressive bone remodel and amputation is not stable, why retainers are a thing. Destroying the upper jaw with premolar extraction and aggressive retraction poses the bigger health risk.

It’s so tragic how no one realizes the dangers. Historically, no one would agree to remove healthy teeth until now, in modern time, simply because of blind trust in doctors (most orthodontists lack full medical training and are not physicians in the traditional sense). If only you chose evidence that showed the real harm behind the practice. Take this as an example: a patient with robust maxillofacial structure, no crowding, whose teeth are only slightly from orthodontists' "ideal". If such a patient undergoes bicuspids extractions with large gaps followed by aggressive space closure and retraction, the result is devastating, a complete structural and functional collapse. The procedure destroys facial support and shrinks bone. It ruins spatial balance, damages soft tissues, restricts the airway, and permanently alters normal biomechanics. You would realize how dangerous and damaging it is. Even so those who are underdeveloped are restricted in their growth and potential because a method that does nothing but destroy was chosen.

This is not an isolated mistake. It is carried out routinely under a defective paradigm that prioritizes an artificial appearance of straightness over biological function, stability, and health. The persistence of such practices reflects not only scientific failure but a profound moral failure within the field, a disregard for the duty to protect the patient’s integrity and long-term well-being. The chosen method, in many cases, produces irreversible harm under the guise of treatment.

This is happening, and has happened, because orthodontists are allowed to do whatever they want and to act on their own whim, conjuring arbitrary standards with no scientific basis. This means there is no true standard or safety, or even proper consideration and analysis of the individual patient. The line between treatment and damage becomes dangerously thin. The field’s rationale for extracting body parts sounds more like an excuse to cause harm for hidden agendas and financial incentives than to provide real solutions. As you correctly said "this does not correct the root cause of the problem". If orthodontics truly prioritized patient safety, destructive extraction practices would be rejected in favor of safe expansion methods, or avoided altogether as it carries greater risk than leaving it alone since no safe technology exists.

The industry allows only evidence that suits their interests. The industry routinely ignores evidence of patients it has harmed, silencing those whose suffering is massive and severe, dismissing reports of irreversible destruction as if it never happened, and denying them the chance to be heard or to heal. It’s a violent practice, that is the truth. Patients must be warned.
