Can protruding mouth be self-corrected?
The degree of protrusion differs between the upper and lower teeth. If only a “protruding mouth” surgery (e.g., maxillary or mandibular setback alone) is performed, it may result in an unnaturally sunken or flattened appearance of the lips. Therefore, bimaxillary (double-jaw) surgery is often required for optimal correction. Can dental–maxillofacial protrusion (“buck teeth” or “prognathism”) self-correct? Below, we address this question.

Can Dental–Maxillofacial Protrusion Self-Correct?
Dental–maxillofacial protrusion generally cannot self-correct. Patients are advised to consult a qualified oral and maxillofacial specialist at an accredited hospital. This condition is a relatively common craniofacial deformity, often associated with malocclusion and dental malalignment. If the protrusion stems primarily from dental malpositioning, orthodontic treatment—such as braces—can effectively realign the teeth and thereby improve the appearance of lip and dental protrusion.
Orthodontic appliances apply controlled, gentle forces to the teeth, gradually guiding them into proper alignment. During treatment, the orthodontist regularly adjusts the appliance’s force to ensure precise tooth movement while safeguarding periodontal health and minimizing risk to surrounding tissues.
If the protrusion results from abnormal jawbone development, orthognathic surgery is indicated. This well-established surgical procedure corrects skeletal discrepancies, repositions misaligned teeth, and restores harmonious occlusion and facial balance. Prior to surgery, patients must maintain excellent oral hygiene and fast as instructed. During orthodontic treatment, avoid chewing hard or excessively sticky foods—such as pork ribs or rice cakes—to prevent appliance damage or complications.
The above outlines whether dental–maxillofacial protrusion can self-correct. We hope this information is helpful to you.
