Underbite correction treatment addresses the misalignment of your lower and upper teeth by realigning jaw position and tooth arrangement. When your lower jaw protrudes beyond your upper jaw, you are experiencing a bite irregularity known as an underbite. If you are dealing with an underbite, overbite, open bite or crossbite, the team at Wright Orthodontics specializes in corrective orthodontics and occlusion balance. We offer comprehensive solutions including crossbite orthodontic correction, open bite braces treatment, deep bite correction braces and overbite correction braces to restore function, comfort and confidence in your smile.

Underbite correction overview

Defining underbite

An underbite, clinically known as a Class III malocclusion, occurs when your lower teeth overlap your upper teeth more than they should [1]. Severity ranges from a mild edge-to-edge bite to pronounced jaw protrusion called prognathism. Underbite correction treatment aims to reposition teeth and jaws so that your bite aligns properly, improving chewing efficiency and speech articulation.

Effects on function and appearance

Beyond aesthetics, an untreated underbite can lead to uneven tooth wear, enamel erosion, and increased risk of temporomandibular joint (TMJ) discomfort. You may experience jaw pain, headaches or difficulty biting into foods. Socially, a pronounced lower jaw can affect your facial balance and self-esteem. Correcting your underbite not only enhances your smile but also supports long-term oral health and overall well-being.

Causes and diagnosis

Genetic and developmental factors

Underbites often have a genetic component—if one or both of your parents had jaw misalignments, you may inherit a similar skeletal pattern. Childhood habits such as thumb-sucking, tongue thrusting or prolonged pacifier use can influence jaw growth and contribute to bite irregularities. These factors can result in a skeletal jaw discrepancy treatment scenario requiring targeted orthodontic guidance.

Clinical evaluation and imaging

Your journey begins with a thorough examination at Wright Orthodontics. We review your dental history, perform an oral exam and capture diagnostic records including panoramic X-rays, cephalometric images and digital 3D scans. Early screening between ages seven and ten is ideal because jaw bones are still developing, making non-surgical correction more effective [2]. If you qualify, we incorporate early intervention orthodontics and growth guidance orthodontic treatment to steer jaw alignment in the right direction.

Non-surgical treatment options

Braces and retainers

Traditional braces—whether metal, ceramic or lingual—are the cornerstone of underbite correction treatment for mild to moderate cases. By applying controlled pressure through brackets and archwires, braces shift teeth into their ideal positions over 24 to 36 months. Once braces come off, retainers hold your teeth in place, preventing relapse [1]. You can learn more about aligning teeth with braces in our guide on bite correction with braces.

Functional appliances

For growing patients, functional orthodontic appliances guide jaw development without surgery. Devices such as the reverse-pull face mask attach to a palatal expander device and use gentle traction to pull the upper jaw forward before bone fusion. These functional orthodontic appliances can correct mild underbites in as little as six to twelve months when used in the optimal age window.

Clear aligners

Invisalign and similar clear aligner systems offer a discreet way to address mild underbites. Custom-made, removable aligners gradually shift teeth and can resolve some jaw alignment concerns without metal hardware. Treatment spans from six months for minor adjustments to 18–24 months for complex cases, depending on the severity of your malocclusion and compliance with daily wear [3].

Tooth extraction and spacers

When tooth crowding contributes to your underbite, strategic extraction of one or more teeth may be necessary. Creating space allows braces or aligners to reposition remaining teeth effectively. In some plans, we use orthodontic spacer placement between teeth before braces to ensure sufficient room for movement and optimal bite alignment.

Surgical treatment approaches

Orthognathic surgery fundamentals

For adults or severe underbites unresponsive to non-surgical methods, orthognathic (jaw) surgery may be the most reliable path to a balanced bite. During this procedure, an oral surgeon repositions the upper jaw, lower jaw or both to achieve harmonious occlusion and facial symmetry [4]. At Wright Orthodontics, we collaborate closely with surgical specialists to integrate jaw alignment orthodontics and ensure a seamless treatment plan.

Virtual planning and 3D printing

Advances in 3D imaging and virtual surgical planning allow your surgical team to model jaw movements precisely. Using 3D-printed guides, surgeons can make highly accurate bone cuts and reposition your jaws with minimal deviation, reducing intraoperative risk and enhancing postoperative comfort.

Coordinated orthodontics and surgery

Orthognathic surgery is typically preceded by 12–18 months of preoperative orthodontics to align teeth and decompensate bite compensations. After surgery, your braces remain in place for another six to twelve months to fine-tune tooth position and solidify your new bite. Full bone healing takes about 12 weeks, although most patients return to normal activities within one to three weeks following surgery [4].

Treatment timeline and expectations

Your underbite correction journey varies with age and chosen method. Below is a typical timeline:

From your initial consultation through retainer placement, you can expect six months to three years before underbite correction is complete. Your orthodontist at Wright Orthodontics will review your personalized treatment timeline, key milestones and any lifestyle adjustments required along the way.

Recovering after correction

Post-surgical care

If you undergo jaw surgery, you will follow a soft or liquid diet for several weeks and take prescribed pain management medications. Regular follow-up visits ensure proper healing and allow your surgical team to remove any fixation hardware as needed. Swelling typically subsides within two to four weeks, but complete bone remodeling continues for up to three months.

Retainer wear and follow-up

After braces or aligners, you transition to retainers—initially full-time then gradually to nightly wear. Retention is critical to maintain your underbite correction treatment results. We schedule regular check-ups to monitor retainer fit, address any minor shifts and perform occlusal adjustment therapy if needed to refine your bite.

Maintaining your results

• Maintain excellent oral hygiene with brushing, flossing and routine cleanings to protect tooth enamel and gum health in your newly aligned bite.
• Attend biannual orthodontic check-ups to ensure that your teeth remain in their prescribed positions.
• Schedule an occlusal evaluation if you notice changes in your bite, wear patterns or jaw comfort. Bite balancing orthodontics can address minor shifts before they become larger issues.
• If you develop other bite irregularities—such as a crossbite or open bite—our team can recommend targeted treatments, including crossbite orthodontic correction or open bite braces treatment, to preserve harmonious occlusion.
