What should I do about protruding lips?

Introduction
Protruding lips may result from dental protrusion or skeletal (jaw) protrusion and can be treated with orthodontic appliances (e.g., braces) or surgery. Dental protrusion refers to teeth positioned beyond their normal anatomical range; such protrusion may contribute to lip protrusion and can be caused by genetic factors or abnormal craniofacial development.

“Protruding mouth” refers to a condition in which both the upper and lower jaws protrude simultaneously. When the mouth protrudes, the perioral area and nose appear relatively flattened or depressed, the chin appears recessed, and nasolabial folds become more pronounced.

What can be done about a protruding mouth?

A protruding mouth may result from either dental protrusion (protruding teeth) or skeletal jaw protrusion (protruding jawbones), and can be treated with orthodontic appliances (e.g., braces) or surgical intervention.

Dental protrusion refers to teeth extending beyond their normal anatomical position. Such protrusion may contribute to an outwardly projecting mouth appearance. Causes may include genetic factors or abnormal craniofacial development. Dental protrusion not only affects facial aesthetics but may also impair masticatory function. Additionally, malaligned teeth increase susceptibility to oral diseases. Orthodontic treatment—such as braces—can effectively correct dental crowding and tooth protrusion.

The jaw consists of the maxilla (upper jaw) and mandible (lower jaw); protrusion of either structure can lead to a protruding mouth appearance. Jawbone protrusion may stem from poor chewing habits or developmental abnormalities during childhood. Surgical orthognathic correction is typically required to reposition the malformed jawbones and restore facial harmony and balance.

During recovery, meticulous oral hygiene must be maintained to prevent food debris accumulation and reduce infection risk.

The above outlines available management options for a protruding mouth. We hope this information is helpful to you.

Surgical procedure for bony protruding mouth
Bony protruding mouth is generally treated with a combination of orthodontics and orthognathic surgery, with the orthognathic procedure typically performed after orthodontic treatment. The corrective surgery for bony protrusion involves exposing the bone tissue by layer-by-layer dissection, then using osteotomy instruments to cut the bone, followed by repositioning the upper and lower jaws as a whole into the proper alignment and securing them with titanium screws to correct the malocclusion. Postoperative care should be carried out according to medical instructions.

Comparison between normal jaw and protruding jaw
Under normal circumstances, the position and angle of the upper and lower jawbones and teeth are relatively parallel; however, in cases of protruding mouth, the position and angle of the upper and lower jawbones and teeth may deviate. Mouth shape is one of the external features of the human body—some individuals have a protruding mouth, while others have a flatter, straighter appearance, depending on the development and morphology of the oral and craniofacial bones.

What causes protruding mouth and thick lips?
In general, protruding mouth and thick lips may be caused by factors such as poor dental development, long-term mouth breathing, or severe fat accumulation in the lips. If symptoms are severe, patients are advised to promptly visit a hospital for examination and diagnosis, and receive targeted treatment under medical guidance. It is also recommended that patients reduce the frequency of consuming sweets to prevent dental damage.

How to correct protruding mouth
In most cases, protruding mouth may be caused by excessive chewing, mouth breathing, malnutrition, facial trauma, periodontal disease, or other factors. Treatment options include orthodontic correction, orthognathic surgery, hyaluronic acid injections, and medication, which should be conducted under a doctor's guidance. In daily life, it is recommended to maintain good oral hygiene, brush teeth regularly, have routine dental cleanings, and avoid bad habits such as mouth breathing and lip biting.

What department should I visit for protruding mouth and enlarged adenoids?
Patients with protruding mouth and adenoid hypertrophy can visit departments such as otolaryngology, snoring clinic, or pediatrics. The adenoids are primarily located at the top of the nasopharynx and fall within the scope of ear, nose, and throat medicine. Adenoid enlargement may result from repeated local inflammatory stimulation leading to hyperplasia and hypertrophy. Protruding mouth and adenoid hypertrophy are features of "adenoidal facies," which typically presents with a high-arched palate, upturned lips, and similar characteristics.

What are the simplest methods for correcting protruding lips?
There is no simple method to reverse protruding mouth. Protruding mouth can be treated through facial exercises, use of oral appliances, hyaluronic acid lip fillers, orthodontic treatment, and orthognathic surgery. It is recommended to visit a reputable hospital and undergo the above procedures under the guidance of a qualified physician to ensure safety and effectiveness. After surgery, it is important to maintain good oral hygiene, avoid strenuous activities, and prevent facial trauma.

Can protruding mouth be self-corrected?
Protruding mouth (prognathism) generally cannot be improved through self-correction; therefore, it is recommended to consult the Department of Stomatology at a reputable hospital. Prognathism is a relatively common maxillofacial deformity clinically associated with malocclusion and dental malformations. If prognathism results from dental malformations, orthodontic treatment—such as wearing braces—can correct the teeth and thereby improve the protrusion.

What should I do if the bone above my teeth is protruding?
1. Orthodontic treatment: Suitable for mild alveolar bone protrusion, typically caused by simple outward protrusion of the teeth alone. 2. For severe alveolar bone protrusion—resulting in prominent overjet (buck teeth), underbite (reverse occlusion), or significant mandibular retrognathia—orthodontic appliances are generally ineffective; in such cases, orthognathic (surgical) correction is usually required.
