How Does the Face Change Before and After Orthodontic Treatment for Protruding Teeth?

Hello, doctor understands that many people are very curious about how the face changes before and after orthodontic treatment for protruding teeth. Especially for individuals with protrusion, underbite, or severe malocclusion, the before-and-after transformation is always a major concern. Today, doctor will explain in detail how orthodontic treatment changes facial appearance and why this process can bring about such comprehensive improvements.

Facial Changes Before and After Orthodontic Treatment for Protruding Teeth

To answer the question how the face changes before and after orthodontic treatment for protruding teeth, doctor must first explain the principle of orthodontics: when protruding teeth are moved into their correct positions on the dental arch, the lips become less prominent, and the chin–nose–lip relationship becomes more harmonious. This significantly reduces mouth protrusion and improves facial profile balance.

Before orthodontic treatment for protruding teeth, the face often appears less harmonious because the upper lip projects excessively, the facial profile lacks balance, and the smile may reveal excessive gingival display. After orthodontic treatment, the teeth are properly aligned and retracted when necessary, allowing the lips to close more naturally, reducing prominence and creating a more refined facial appearance. This is why many people feel that their “face becomes slimmer” or “more delicate” after orthodontic treatment, especially in cases where protrusion is primarily dental in origin.

From a scientific perspective, these changes result from correcting tooth inclination, incisor angulation, soft tissue lip thickness, and occlusion. When all of these factors return to physiological norms, facial balance improves significantly.

Facial Changes Before and After Orthodontic Treatment in Different Cases

Orthodontic Treatment for Underbite

In individuals with an underbite, the lower jaw typically protrudes beyond the upper jaw, causing the face to appear harsh, the profile to look disrupted, and the lower lip to dominate the upper lip. After orthodontic treatment, the incisors are repositioned and the upper and lower jaws are brought into proper relationship, resulting in a softer and more harmonious facial appearance.

Orthodontic Treatment for Protruding Teeth

Individuals with protruding teeth often experience lip protrusion, a “buck-tooth” appearance, excessive gingival display when smiling, and an unattractive facial profile. After orthodontic treatment, the incisors are retracted appropriately, and the bite becomes more balanced. As a result, the lips close naturally, the face appears more refined, and the sensation of excessive lip projection is eliminated. This is the most noticeable transformation in the face before and after orthodontic treatment for protruding teeth.

Treatment of Open Bite

An open bite can make the face appear elongated, expose more teeth when smiling, and make chewing difficult. Once proper occlusion is established, the face becomes more balanced, the smile line appears softer, and the harmony between the upper and lower jaws improves significantly.

Orthodontic Treatment for Misaligned Teeth and Severe Canine Prominence

Misaligned teeth can make the smile appear uneven, create a sense of facial disharmony, and contribute to mild jaw asymmetry. After orthodontic treatment, properly aligned teeth enhance the overall facial appearance, create a more attractive smile, and improve facial balance on both sides.

Degree of Facial Change in Different Individuals

Orthodontic Treatment in Adults

Adults have a more mature and rigid jawbone structure, so facial changes primarily result from tooth movement and soft tissue adaptation. The face before and after orthodontic treatment in adults typically becomes more refined, with softer lips and a more attractive profile, although the transformation is usually not as dramatic as in children. However, in cases of severe protrusion or underbite, the changes can still be very significant.

Orthodontic Treatment in Children

Children have a major advantage because their jawbones are still developing. In addition to aligning teeth, doctors can also influence skeletal growth patterns, resulting in more comprehensive facial changes. Children undergoing orthodontic treatment often experience significant improvements in jaw structure, occlusion, and overall facial contours.

Consequences of Improper Orthodontic Treatment on Facial Appearance Before and After Treatment

Orthodontic treatment performed incorrectly can lead to facial alterations, especially when the applied force is inappropriate or the treatment plan is unsuitable. Some possible consequences include:

• Excessive retraction of the incisors can cause lip retrusion, a sunken facial appearance, and an aged-looking profile.
• Improper occlusion may result in facial asymmetry.
• Non-physiological tooth movement can cause bone loss and gingival recession, making the face appear gaunt or hollow.
• Loss of canine support can make the smile appear unnatural and reduce facial softness.

These situations are commonly encountered when treatment is performed at facilities without specialized orthodontists, without treatment planning based on 3D imaging, or without proper control of orthodontic forces.
