Should You Get Braces for an Underbite? Which Orthodontic Method Is Most Effective?

Hello, an underbite (also known as a Class III malocclusion) not only affects facial aesthetics but can also create difficulties with chewing and may negatively impact the temporomandibular joint over time. The doctor will explain in detail whether orthodontic treatment for an underbite is effective, what treatment options are available, and what considerations are important throughout the orthodontic process.

Causes of an Underbite

The doctor’s direct explanation is as follows: an underbite develops due to an imbalance between the teeth, jawbones, and certain habits formed from an early age. In clinical practice, the most common cause is heredity, where the lower jaw develops excessively or the upper jaw develops insufficiently.

In addition, harmful childhood habits such as prolonged thumb sucking, improper tongue thrusting, mouth breathing, or premature loss of primary teeth can also lead to tooth misalignment and the development of an underbite.

In adults, an underbite may sometimes be associated with teeth erupting in improper positions while the jawbones remain relatively balanced. Identifying the exact cause from the beginning is the key factor in determining whether orthodontic treatment for an underbite will be effective.

Can Orthodontic Treatment Correct an Underbite?

The doctor would like to emphasize that: orthodontic treatment can correct an underbite, but the effectiveness depends greatly on the underlying cause of the condition.

If the underbite is primarily dental in origin, meaning the lower teeth protrude forward or the upper teeth are positioned inward while the jawbones remain relatively normal, orthodontic treatment can effectively reposition the teeth and restore proper bite relationships. In these cases, orthodontic treatment for an underbite provides significant improvements in both function and aesthetics.

On the other hand, if the primary cause is excessive growth of the lower jawbone, orthodontic treatment alone can only improve tooth positioning and cannot completely correct the skeletal discrepancy. In such cases, the doctor may recommend a combination of orthodontic treatment and orthognathic surgery to achieve optimal results.

Current Treatment Methods for Underbite Correction

Today, underbite treatment is no longer limited to a single approach but is personalized according to each patient’s specific condition.

For children and adolescents, doctors often prioritize early intervention using orthodontic appliances or braces to guide and control jaw development. Early treatment can shorten treatment time and reduce the likelihood of requiring surgery later in life.

For adults, orthodontic treatment for an underbite using metal braces, ceramic braces, or Invisalign is widely used when the condition is caused primarily by dental factors. In more complex cases, orthodontic mini-screws (minivis) may be combined with treatment to improve force control. For severe skeletal underbites, corrective jaw surgery combined with orthodontic treatment before and after surgery remains the most comprehensive solution.

Treatment Duration and Important Considerations for Underbite Orthodontics

Regarding treatment duration, how long orthodontic treatment for an underbite takes depends on the severity of the discrepancy and the chosen treatment method. In general, orthodontic treatment lasts between 18 and 30 months. More complex cases or those requiring surgery may take longer.

Throughout treatment, it is essential to strictly follow scheduled appointments, wear retainers as instructed, and maintain excellent oral hygiene to prevent gingivitis and bone loss. Missing follow-up visits or failing to comply with instructions may delay progress and affect the final outcome.

At Gangwhoo Cosmetic Hospital, cases of orthodontic treatment for an underbite are managed using personalized treatment plans based on X-rays, bite analysis, and jawbone evaluation. This allows doctors to accurately recommend the most appropriate treatment approach, helping shorten treatment time while ensuring long-term safety and effectiveness.

If you are unsure about the type of underbite you have and whether it can be treated with orthodontic treatment alone, you should visit Gangwhoo Cosmetic Hospital for a direct consultation and detailed evaluation by an orthodontist.
