Corrective Jaw Surgery: Improving Bite, Function and Facial Balance

Some bite problems cannot be corrected with braces alone. When the upper and lower jaws do not meet properly because of their size or position, orthodontic treatment can align the teeth but may not fully correct the underlying jaw discrepancy.

Corrective jaw surgery, also called orthognathic surgery, moves one or both jaws into a more functional position. It is a major decision and a carefully planned process, but for the right patient, it can improve chewing, speech, comfort, facial balance, and long-term bite stability.

When might jaw surgery be considered?

Orthognathic surgery may be considered for patients with significant jaw-related concerns, including:

• A severe overbite, underbite, open bite, or crossbite
• Difficulty biting or chewing food properly
• Jaw imbalance that affects facial symmetry
• Teeth that do not meet comfortably even after orthodontic treatment
• Chronic strain related to an unstable bite
• Certain sleep-related breathing concerns, when part of a broader assessment
• Facial trauma or jaw growth differences

A noticeable facial difference does not automatically mean surgery is necessary. The key question is whether the jaw position is affecting function, health, comfort, or your ability to achieve a stable bite.

What is the relationship between braces and jaw surgery?

Most patients have orthodontic treatment before and after jaw surgery. Before surgery, braces or clear aligners position the teeth so that they will fit together correctly once the jaws are moved.

This can feel counterintuitive because the bite may temporarily appear worse before surgery. It is a planned phase of treatment, not a setback. I work closely with your orthodontist so that the surgical and orthodontic plans support the same final result.

What happens during corrective jaw surgery?

Jaw surgery is usually performed in a hospital under general anaesthesia. Depending on the diagnosis, surgery may involve the upper jaw, lower jaw, chin, or a combination of these areas.

The bones are repositioned and held in their new position with small plates and screws. In most cases, incisions are made inside the mouth, so visible facial scars are usually avoided.

Your plan is based on detailed records, photographs, dental models or digital scans, X-rays, and three-dimensional imaging. Careful planning is one of the most important parts of achieving a safe and predictable outcome.

What is recovery like?

Recovery requires patience and planning. Most patients need time away from work or school, and swelling is expected in the first few weeks. Initial healing occurs over several weeks, while final settling and orthodontic finishing continue over a longer period.

During early recovery, you may need:

• A liquid or soft-food diet
• Medication for discomfort and swelling
• Time off work, school, or demanding activities
• Follow-up appointments to monitor healing
• Ongoing orthodontic appointments after surgery

Temporary numbness, particularly in the lower lip and chin after lower-jaw surgery, can occur. I discuss the specific risks relevant to your procedure before you decide whether to proceed.

Is jaw surgery only cosmetic?

No. While facial balance may improve, the primary purpose of orthognathic surgery is often functional: helping the jaws and teeth work together more comfortably and predictably.

The best outcomes consider both function and appearance. My approach is to listen carefully to what bothers you, assess the clinical issues thoroughly, and make sure you understand the benefits, limitations, and recovery involved.

Taking the next step

If you have been told that braces alone may not correct your bite, or you struggle with chewing, jaw imbalance, or teeth that do not meet properly, a surgical consultation can provide clarity.

You do not need to decide on surgery at the first visit. The consultation is an opportunity to understand your diagnosis, discuss alternatives, and learn what a coordinated treatment plan with your orthodontist could involve.
