Introduction

For more severe skeletal protrusion (buck teeth), it is recommended to visit a正规 hospital and undergo orthognathic surgery under the guidance of a qualified specialist. This procedure corrects the positional relationship between the upper and lower jaws, thereby improving protruding teeth caused by skeletal issues. The reference cost is generally 20,000–40,000 yuan per session. Noticeable improvement typically appears within three months, although potential complications such as nerve damage or bleeding may occur.

Generally, protruding teeth (buck teeth) can be distinguished as skeletal or dental based on factors such as growth position, tooth morphology, cause of development, dental arch relationship, and treatment methods. The specific analysis is as follows:

1. Growth Position

Skeletal protrusion is primarily caused by bony prominence, manifesting as maxillary protrusion or bimaxillary protrusion; dental protrusion is mainly due to malalignment of the dentition, causing the front teeth or adjacent teeth to be pushed outward.

2. Tooth Morphology

In skeletal protrusion, the shape of the upper and lower jaws is abnormal, with forward protrusion of the jaw bones and surrounding nasal area, resulting in lips that cannot cover the teeth. In dental protrusion, the relationship and shape of the upper and lower jaws are generally normal, with only the teeth projecting forward.

3. Cause of Development

Skeletal protrusion is mostly caused by hereditary factors and congenital genetic predisposition. If there is a family history of protruding teeth, offspring are more likely to develop the condition. Dental protrusion usually results from abnormal growth and irregular alignment during the development of permanent teeth, often due to acquired oral habits such as lower lip biting or mouth breathing.

4. Dental Arch Relationship

In skeletal protrusion, the dental arch relationship is typically not significantly abnormal, with relatively normal development of the upper and lower jaws. In dental protrusion, the dental arch relationship is abnormal, characterized by outward protrusion of the upper front teeth, which may be accompanied by protrusion of the lower front teeth.

5. Treatment Methods

Skeletal protrusion generally requires complex treatments such as orthognathic surgery to correct jawbone relationships. Dental protrusion can usually be effectively corrected through orthodontic treatment alone.

For severe cases of skeletal protrusion, it is recommended to visit a reputable hospital and undergo orthognathic surgery under the guidance of a qualified specialist. This involves adjusting the positional relationship between the upper and lower jaws to improve tooth protrusion caused by skeletal issues. The typical cost ranges from 20,000 to 40,000 yuan per procedure. Improvement is usually visible within 3 to 6 months, although potential complications such as nerve damage or bleeding may occur.

What should I do if my child has protruding front teeth?

In general, children developing protruding teeth is usually caused by factors such as genetics, bad habits, dietary habits, calcium deficiency, and allergic rhinitis. Treatment options include general therapy, physical therapy, surgical intervention, and medication. It is important to cultivate good oral habits, ensure a balanced diet, adjust eating habits, and appropriately consume harder foods to stimulate oral development.

Can protruding teeth be corrected at age 45?

Whether 45-year-old individuals with protruding teeth can undergo orthodontic treatment depends on their oral health condition. Orthodontic correction is possible for those with good oral health and no severe periodontal issues. However, if serious periodontal disease, alveolar bone loss, or loose teeth are present, orthodontic treatment is not advisable until underlying oral conditions are properly treated. During orthodontic treatment, special attention must be paid to oral hygiene, and tools such as water flossers and dental floss should be used to clean between teeth thoroughly.

Can protruding teeth become longer?

Under normal circumstances, protruding teeth (buck teeth) do not noticeably increase in length as a person ages. However, changes in tooth position or surrounding tissues may create the visual or physical impression that the teeth have become longer; this change is not due to actual tooth growth. If significant changes in the appearance of protruding teeth are noticed, or if symptoms such as gum recession or tooth sensitivity occur, it is important to seek timely evaluation and treatment from a dental professional.

Is orthodontic treatment effective for protruding teeth caused by adenoid face?

Orthodontics refers to dental alignment. Adenoid facies is a complication caused by adenoid hypertrophy. The effectiveness of orthodontic treatment for protruding mouth caused by adenoid facies mainly depends on individual conditions. If the bones are still developing and the protrusion is related to the teeth, timely orthodontic treatment usually has some effect. However, if bone growth has ceased or the protrusion is unrelated to the teeth, orthodontics may not be effective.
