Can an adult’s protruding front teeth be improved with orthodontic treatment?

Hello, this is S Leader Dental Hospital, a Seoul orthodontic dental clinic.

The protrusion of the front teeth, commonly called “buck teeth,” is often thought of as only an aesthetic issue, but in many cases it also comes with functional discomfort. In particular, there are many adults who lose confidence because their protruding front teeth make their mouth stand out whenever they smile, or because it is difficult to close their lips even when their face is expressionless.

If the orthodontic timing was missed during adolescence, or if the protrusion gradually worsened after growth was completed, it can often be sufficiently improved through adult orthodontic treatment. In fact, adults often have more thorough self-management and better cooperation with treatment, so the results are sometimes even more stable.

Protruding front teeth are not simply an appearance issue.

When the front teeth protrude, the upper front teeth are excessively tilted forward or positioned in front of the lower lip, making it difficult for the lips to close. This type of dental misalignment not only makes it hard to close the mouth naturally, but can also cause wounds from constant lip friction or recurring mouth ulcers. In addition, protruding front teeth can fail to control airflow in sounds that are sensitive to wind, leading to inaccurate pronunciation. In severe cases, it may also be associated with nasal congestion or mouth breathing, causing the inside of the mouth to dry out easily and increasing the risk of cavities and gum disease.

As such, protruding front teeth can affect not only appearance but also everyday function, which is why orthodontic treatment is often both possible and necessary even for adults. In adults, since tooth and bone growth has been completed, treatment planning can be made more clearly, and if the physiological response needed for tooth movement is sufficient, age itself is not a major limitation. On the contrary, the impression before and after treatment can improve dramatically, helping restore confidence and even changing the way one speaks,

smiles, and the facial contour, which often leads to a very high level of treatment satisfaction.

In adult protruding front teeth correction, the decision on whether or not to extract teeth is an important factor.

In most cases, the decision on whether to extract teeth plays an important role in adult protruding front teeth correction. If there is not enough space for proper alignment of the teeth and the lip protrusion is severe enough that facial profile improvement should also be considered, premolar extraction is generally performed to secure space. By moving the protruding front teeth backward into that space, the mouth can naturally retract, and a smoother look around the mouth can be expected from the side profile as well.

On the other hand, if the protrusion is mild or can be improved through tooth alignment alone, non-extraction treatment is possible. In such cases, the treatment period is relatively shorter and the patient’s psychological burden is reduced. However, the decision on whether to extract teeth is not made based solely on tooth alignment; it must be determined by considering various factors such as the overall facial appearance, bite condition, and available gum support, so a detailed analysis through a precise examination is necessary.

The appropriate orthodontic appliance is selected according to each patient’s dry mouth condition and needs.

Orthodontic methods can be chosen in various ways depending on the patient’s needs and oral condition. If you want treatment that is not noticeable, clear aligners (such as Invisalign) can be used. If more delicate tooth movement is needed, ceramic or lingual brackets may be used. The treatment period varies depending on the patient’s condition and plan, but generally takes about 1.5 to 2 years. After treatment, a retainer must be worn to prevent the aligned teeth from shifting back. If retainer wear is neglected, the teeth may be pulled back toward their original position due to relapse forces, which can reduce the orthodontic effect or make retreatment necessary. Thorough post-treatment management is essential.

Orthodontics is not simply a treatment that changes the position of the teeth. It improves quality of life in many ways, including facial profile improvement, better chewing function, and easier oral hygiene management. In particular, improving highly visible areas such as protruding front teeth affects not only appearance but also social activities and interpersonal relationships. In fact, many adult patients say after orthodontic treatment,

“I'm more confident when I smile,” “I no longer have to keep my mouth closed when taking photos,” and “My side-profile complex has disappeared.”

"Protruding front teeth can improve not only appearance but also function.

Start a confident change with orthodontic treatment."

If you are worried that it may be too late for orthodontic treatment because of your age, it is best to first receive a precise diagnosis through an examination to see whether treatment can be carried out without difficulty.

By comprehensively analyzing the shape of the jawbone, the condition of the alveolar bone, and gum support—factors that cannot be determined from tooth alignment alone—it is possible to establish whether treatment is appropriate and what the plan should be. Through consultation with a specialist, you can find the orthodontic method best suited to your situation. Orthodontic treatment is worth considering not simply because the front teeth look protruded, but especially if it is causing discomfort.
