Dongdaemun-gu Dental Clinic Orthodontics: How Is Crossbite and Underbite Correction Done?

Hello, this is S Leader Dental Hospital, a Dongdaemun-gu dental clinic.

Among those considering orthodontic treatment, many visit the clinic because of crossbite or underbite. Crossbite refers to a condition where the upper and lower teeth bite together in the reverse of normal alignment, and an underbite means the lower jaw grows forward and long enough to change the shape of the face.

These issues are not simply about tooth alignment; they also affect jaw growth, facial shape, and functional aspects, making early diagnosis and treatment especially important in orthodontic cases.

Problems Caused by Crossbite and Underbite

Crossbite and underbite are associated not only with aesthetic discomfort but also with various functional problems. They can make it difficult to chew food properly, placing a burden on digestive function, and can also cause unclear pronunciation, leading to stress during conversation. In addition, if an incorrect bite is maintained for a long period, excessive pressure is placed on the temporomandibular joint, which can lead to temporomandibular disorders, headaches, and even neck and shoulder pain.

For children in their growth period, concern about appearance can lower self-esteem, and in adults, it often appears as a lack of confidence in social life.

When Is the Best Time to Start Orthodontic Treatment?

Children in their growth period are at a stage when jawbone growth is active, so starting orthodontic treatment early can effectively encourage or restrain jaw growth. In particular, if crossbite or underbite is identified and treatment begins in the lower grades of elementary school, significant results can often be achieved in a relatively short period of time, and the likelihood of needing surgical treatment as an adult can be reduced.

However, even if someone is already an adult, orthodontic treatment is still fully possible. Since jaw growth has stopped in adults, treatment focuses on moving the teeth, and in some cases it is combined with surgical treatment such as double-jaw surgery. What matters is receiving an accurate diagnosis regardless of age and choosing the optimal treatment method for the current condition.

How Crossbite and Underbite Are Treated

Early treatment during growth

If the growth plates have not yet closed, orthodontic appliances can be used to promote upper jaw growth and restrain lower jaw growth, helping restore balance between the jaws. The earlier treatment begins, the more stable and natural the results tend to be, and the greater the improvement in facial shape.

Adult treatment

In adults, since jawbone growth has already been completed, treatment mainly focuses on adjusting tooth alignment. Orthodontic appliances are used to correct tooth position and bite alignment, and if necessary, treatment may be combined with surgical care to improve both the bite and aesthetics.

Partial orthodontics and functional appliances

If symptoms are mild, improvement may be achieved relatively simply through partial orthodontics or functional appliances. However, because the causes and symptoms of crossbite and underbite vary, it is important to establish an individualized treatment plan through precise diagnosis.

[Why Precise Diagnosis Is Important]

Crossbite or underbite should not be viewed as merely a tooth-alignment problem. For stable treatment, all factors must be considered comprehensively, including jawbone structure, the direction of the tooth roots, bite condition, and temporomandibular joint position. At Dongdaemun-gu dental clinic, a personalized orthodontic plan is established through detailed examinations such as CT scans, 3D oral scans, and bite analysis. This systematic diagnosis helps reduce unnecessary treatment and is very helpful in achieving stable long-term results.

How Long Does Treatment Take, and How Is It Managed?

The treatment period for crossbite and underbite correction varies depending on the individual’s condition, but on average it takes about 1.5 to 3 years. During treatment, it is important to visit regularly for appliance adjustments and to maintain thorough oral hygiene. In particular, orthodontic appliances can easily trap food and bacteria, so careful brushing and oral rinsing are necessary. Regular checkups are also recommended so that even small problems can be detected and addressed early.
