Underbite Correction
An underbite occurs when the lower front teeth sit ahead of the upper front teeth when biting together. Underbite correction aims to improve this bite relationship, but the right approach depends on whether the problem involves tooth position, jaw development or both.
Some patients can be treated with orthodontics alone. Others need growth-guiding treatment or a combination of orthodontics and jaw surgery.
Quick Answer: How Is an Underbite Corrected?
Underbite correction may involve braces, clear aligners, growth-guiding appliances or jaw surgery combined with orthodontics. Braces can correct selected dental underbites, while significant differences in jaw position may require a surgical assessment. Growing children may have treatment options that are not available after jaw growth has finished. An orthodontic examination is needed to identify suitable options, estimate costs and explain the expected timeline.
If you are wondering what is an underbite, it is an issue that goes far beyond aesthetics. An uncorrected underbite can lead to a host of functional problems:
- Difficulty Chewing and Speaking:The misalignment prevents the upper and lower teeth from meeting correctly.
- Uneven Wear on Underbite Teeth:Certain teeth take all the pressure, leading to excessive and premature wear.
- Chronic Pain:It is a major cause of underbite jaw pain as the joint (TMJ) is constantly strained.
Fortunately, modern dentistry offers effective solutions for underbite correction at any age. The right treatment path, whether it addresses a mild underbite or a severe underbite, depends heavily on the cause (dental vs. skeletal) and your age.
What Determines the Right Approach to Underbite Correction?
The right approach depends on the cause of the underbite, remaining jaw growth and the changes needed to improve the bite.
An orthodontist distinguishes between:
- Dental underbite: Tooth position or inclination contributes to the reversed bite.
- Skeletal underbite: Differences in the size or position of the jaws contribute to the problem.
- Functional shift: The way the teeth meet causes the lower jaw to move forward when closing.
Assessment may include an examination, photographs, dental scans or impressions, and appropriate X-rays. Tooth and gum health, facial relationships and treatment goals also influence the recommendation.
The visible size of an underbite does not determine treatment on its own. Similar-looking bites can have different underlying causes.

How Do You Fix an Underbite?
Underbite treatment may involve guiding growth, moving teeth or surgically repositioning the jaws. The appropriate method depends on the diagnosis rather than the appearance of the teeth alone.
Early Underbite Correction in Children
This path is reserved for children and young teenagers whose jaws are still developing. Orthopedic appliances are used to modify jaw growth and can often prevent the need for more drastic measures later in life.
- Reverse-Pull Headgear (Facemask): This appliance gently pulls the upper jaw forward, encouraging it to catch up with the lower jaw's growth.
- Palatal Expander: Often used in conjunction with a facemask, this device gradually widens the upper jaw, creating space for proper alignment.

Do Braces Fix an Underbite?
Yes, braces can correct selected underbites when moving the teeth can achieve an acceptable bite. Braces for underbite may be combined with prescribed elastics or other appliances.
However, braces move teeth; they do not surgically reposition the jawbones. A substantial skeletal discrepancy may therefore require more than braces alone.
Clear aligners may also be suitable for selected cases, sometimes with attachments or elastics. Suitability depends on the required tooth movements, bite complexity and ability to follow the prescribed wear schedule.

When Is Jaw Surgery Needed for Underbite Correction?
Jaw surgery may be considered when a significant skeletal discrepancy cannot be adequately addressed through orthodontic tooth movement alone. It is generally planned after jaw growth has finished.
An orthodontist and an oral and maxillofacial surgeon coordinate treatment. Depending on the diagnosis, surgery may reposition the upper jaw, lower jaw or both. Orthodontics is commonly required before and after the procedure.
Can an Underbite Be Fixed Without Surgery?
Yes, some underbites can be corrected without surgery, particularly when the problem is mainly related to tooth position. Growing children may also have options that use remaining growth.
In selected cases, orthodontic camouflage can improve how the teeth meet without correcting the underlying jaw relationship. This approach has limits and may not achieve the same facial changes or skeletal correction as jaw surgery.
Ask your orthodontist what a non-surgical plan can correct, what differences would remain and whether the proposed tooth movements are suitable for your gum and bone support.
Patients considering surgical orthodontics should discuss expected benefits, risks, alternatives and recovery with their treating team.
How Much Does Underbite Correction Cost in Toronto?
Underbite correction cost depends on the diagnosis and whether treatment involves orthodontics alone, multiple treatment phases or orthodontics combined with jaw surgery. A personalised estimate requires an examination and a written treatment plan.
The main factors affecting underbite treatment cost include:
- The complexity of the bite and required tooth movements.
- The type of braces, aligners or additional appliances.
- Whether treatment involves one phase or multiple phases.
- Diagnostic records and separately billed dental procedures.
- Retainers and follow-up arrangements.
- Surgical, hospital or anaesthesia charges, where applicable.
When comparing an underbite treatment price, check what the estimate includes. Ask whether records, appointments, retainers and additional procedures are included or billed separately.
York Orthodontics’ braces pricing guide provides general background on orthodontic fees. These figures should not be treated as a personalised quote for underbite correction or jaw surgery.
Is Pre-Authorization Required for Underbite Treatment?
Your insurer may require a treatment estimate, predetermination or pre-authorization before underbite treatment begins. The terminology and requirements vary between plans.
Before starting, ask your insurer to confirm:
- Whether orthodontic treatment is included.
- Any age restrictions, waiting periods or lifetime maximums.
- Which treatment records and forms are required.
- How benefits are paid during treatment.
- Whether surgery requires a separate coverage review.
- Your expected out-of-pocket costs.
Approval of orthodontic benefits should not be assumed to cover jaw surgery or related charges. Obtain written information about eligible services and ask how changes to your coverage could affect reimbursement.
The Government of Canada’s current CDCP coverage information states that orthodontic services are not currently available under the plan. Check the official guidance when arranging treatment, because program rules can change.
What Modern Technology Is Used for Underbite Correction?
Modern technology can support orthodontic records, appliance design and treatment planning. It does not replace diagnosis or make every underbite suitable for non-surgical treatment.
Examples include:
- Digital dental scans: Records of the teeth and bite used for planning and appliance fabrication.
- Customised braces: Systems such as LightForce use digital planning and 3D-printed brackets designed for individual teeth.
- Surgical planning tools: The surgical team may use planning tools and personalised guides appropriate to the procedure.
York Orthodontics lists custom braces among its braces treatment options. Their suitability for underbite correction depends on the individual diagnosis and treatment goals.
The latest technology is not automatically the most appropriate choice. Ask how a recommended system affects your treatment plan, its limitations and the overall cost.
What Is the Recovery Time After Underbite Correction?
Recovery depends on the treatment performed. Adjusting to braces or aligners is different from recovering after jaw surgery, and surgical recovery is only one part of the overall treatment timeline.
| Treatment | Recovery considerations |
|---|---|
| Braces or aligners without surgery | Temporary tooth tenderness or appliance irritation may occur. There is no jaw-surgery recovery period unless a separate procedure is performed. |
| Growth-guiding appliances | Adaptation depends on the appliance and prescribed wear schedule. |
| Orthodontics combined with jaw surgery | Recovery includes swelling, dietary changes and activity restrictions. Orthodontics commonly continues after surgery. |
How Long Does Swelling Last After Underbite Surgery?
Facial swelling is expected after corrective jaw surgery and is often greatest around the second or third day. It generally improves over the following weeks, although residual swelling may take months to settle.
Some hospital guidance recommends allowing around three weeks away from work after jaw surgery. Your own recovery time may differ according to the procedure, healing and physical demands of your job.
Follow your surgeon’s instructions about food, exercise, oral hygiene and returning to normal activities. Seek urgent medical help for breathing difficulty, and contact your surgical team promptly about unexpected or worsening symptoms.

Frequently Asked Questions (FAQs)
Yes. Adults can be assessed for underbite correction when their teeth, gums and supporting structures are suitable. Treatment depends on whether tooth movement alone can achieve the goals or whether a surgical assessment is needed.
The American Association of Orthodontists recommends a first orthodontic assessment by age seven. If an underbite or difficulty biting is noticed earlier, ask your dentist whether an earlier referral is appropriate.
Clear aligners may treat selected dental underbites, sometimes with attachments or elastics. They cannot independently reposition substantially mismatched jawbones, so suitability requires an orthodontic assessment.
It may, but the extent depends on the treatment. Moving teeth and surgically repositioning jaws can produce different facial changes, so discuss the expected effects and limitations of your proposed plan.
The timeline depends on the diagnosis, remaining growth and whether surgery is included. Ask for an estimate that separates orthodontic preparation, any surgical recovery, finishing treatment and retention.
