A Case That Challenges Two Common Assumptions

A Case That Challenges Two Common Assumptions

In a recent TikTok, Dr. Lucas Shapiro of Wall Street Orthodontics shared a real patient case that quietly challenges two assumptions patients hear constantly online: that extractions ruin facial aesthetics and airway function, and that patients who've had extractions don't really need to wear retainers afterward.

This particular patient had four premolars extracted during treatment. Years later, he has excellent facial balance and no sleep or airway issues. But he also experienced something else: his teeth relapsed anyway, despite the extractions. Both parts of this case matter, and both push back on ideas that circulate widely in online orthodontic discussions.

Myth #1: Extractions Automatically Harm Facial Aesthetics or Airway

There's a persistent belief, amplified heavily on social media, that extracting premolars during orthodontic treatment automatically leads to a flatter profile, a "dished-in" face, or long-term airway and sleep problems. We addressed this directly in an earlier post on whether orthodontic extractions harm facial aesthetics, and this patient's outcome is a real-world example of why that blanket claim doesn't hold up.

This patient had four premolars extracted and, years later, shows strong facial balance with no sleep or airway concerns at all. That outcome isn't an accident — it's the result of proper diagnosis and treatment planning at the outset. Extractions aren't inherently harmful to the face or airway; poorly diagnosed extractions, performed without regard for the patient's underlying skeletal pattern and airway anatomy, are what create those risks.

This is exactly why airway dentistry principles matter at every stage of treatment planning, not just for patients being treated for sleep apnea or breathing concerns. Evaluating facial balance, jaw relationships, and airway space before deciding whether (and how) to extract helps ensure the outcome matches this patient's experience rather than the outcomes critics point to online. Our post on airway-focused orthodontics goes deeper into how these evaluations are made, and our Sleep Apnea Treatment page covers how airway health is addressed when it is a concern.

Myth #2: Extraction Patients Don't Need Retainers

The second point in this case is arguably even more important for long-term results: some orthodontists argue that patients who've had extractions don't need to wear retainers afterward, on the theory that the closed extraction spaces provide some kind of built-in stability. Dr. Shapiro pushes back on this directly, and this patient's own relapse is proof of why.

Retention isn't about whether space was closed through extractions or achieved without them. Teeth are held in position by a complex balance of periodontal fibers, muscle forces from the lips, cheeks, and tongue, and ongoing changes in the jaw as we age — none of which stop applying pressure just because a case involved extractions. As we discussed in our post on why teeth shift years after braces, orthodontic relapse is common in adults generally, and extraction cases are not an exception to that rule.

In other words: if you don't wear retainers, your teeth can shift back toward their original position, whether or not premolars were ever removed.

Correcting Relapse: What Are the Options?

For patients who experience relapse after extraction treatment (or any orthodontic treatment), the good news is that correction is usually much faster and less involved than the original treatment. Depending on the severity and location of the shifting, options include:

• Braces for more involved corrections
• Invisalign clear aligners for a discreet, removable option
• C5 Hidden Orthodontics, a completely invisible wire bonded behind the front teeth, ideal for mild to moderate relapse
• Lingual Braces, another fully hidden option for adults who want correction without visible appliances

Each of these can effectively correct minor relapse, and the right choice depends on how significant the shifting is and the patient's preference for visibility, comfort, and treatment timeline.

The Real Takeaway: Retention Is Not Optional

Whether you had extractions, expansion, or no space-related treatment at all, retention is what protects your results long after active treatment ends. At Wall Street Orthodontics, every patient — regardless of treatment type — receives personalized guidance on Retainers, because the mechanics that created your smile don't determine whether it needs ongoing protection. Every finished case does.
