Introduction
Why do teeth shift back even after braces or aligners? For years, the answer has been “wear your retainer.” But what if that’s not enough?
A compelling literature review published by Genesis Publications reveals that muscle function—especially tongue and lip posture—may be the missing piece in preventing orthodontic relapse. This research validates what we at MyoAir know firsthand: lasting results require addressing both structure and function.
Summary of Key Findings
1. Muscle Patterns Can Undermine Orthodontic Work
The tongue, lips, and cheeks exert gentle but persistent pressure on the teeth 24/7. If these forces remain unbalanced—due to low tongue posture, mouth breathing, or tongue thrust—teeth can gradually drift out of alignment, regardless of retainer use.
2. Retention Isn’t Enough
Long-term or even permanent retainer use may not prevent relapse if dysfunctional muscle habits are present. Without correcting the source of these forces, relapse remains a strong possibility, especially in pediatric cases where oral habits are still forming.
3. Myofunctional Therapy Can Prevent Relapse
The review highlights that orofacial myofunctional therapy (OMT)—which trains the tongue, lips, and jaw to function in harmony—can significantly improve post-orthodontic outcomes. OMT helps:
-
Establish proper nasal breathing
-
Promote correct tongue posture and swallowing patterns
-
Improve lip seal and orofacial tone
When integrated with orthodontics, OMT increases stability and long-term success.
Why This Matters at MyoAir
At MyoAir, we specialize in identifying and correcting the muscular imbalances that contribute to relapse. We collaborate with orthodontists and dental professionals to provide a comprehensive, airway-focused approach to treatment that doesn’t stop at straight teeth—it builds a healthy foundation for life.
