Corrective Jaw Surgery: What It Treats and How It Works
Most bite problems can be corrected with braces alone. But when the upper and lower jaws themselves are out of proportion or out of alignment, teeth straightening is not enough. This is where corrective jaw surgery, also called orthognathic surgery, comes in. It repositions the jawbones so the bite, facial balance and jaw function all improve together.
What Corrective Jaw Surgery Treats
Jaw surgery is considered when the problem lies in the bones supporting the teeth, not just the teeth themselves. Common conditions include:
- Underbite: the lower jaw is positioned further forward than the upper jaw, so the lower teeth sit ahead of the upper teeth.
- Overbite or recessed lower jaw: the lower jaw is set back, causing the upper teeth and jaw to appear overly prominent.
- Open bite: the front teeth do not meet even when the back teeth are closed together, often making chewing and speech difficult.
- Facial asymmetry: one side of the jaw has grown differently from the other, leading to a visibly uneven face or crooked chin.
- Jaw-related breathing or sleep issues: in some cases, a small or set-back jaw contributes to airway narrowing.
These issues are usually noticed well before adulthood, but surgery is typically only recommended once jaw growth is complete, which is why most patients are in their late teens or adult years.
How Treatment Is Planned With Braces
Corrective jaw surgery is almost never a standalone procedure. It is planned as a combined effort between your orthodontist and an oral and maxillofacial surgeon, usually in three phases.
1. Pre-surgical orthodontics
Braces are placed first, but not to fix the bite. Their job at this stage is to align and level the teeth within each jaw so that once the jaws are repositioned, the teeth will fit together correctly. This phase often takes close to a year, and interestingly, the bite may look slightly worse during this period as the teeth are decompensated from years of adapting to the misaligned jaw.
2. Surgical planning
Detailed records are taken, including X-rays, photographs, and sometimes 3D scans. These help the surgical team plan the exact movement needed for the jaw or jaws, down to the millimetre. Many clinics now use computer-assisted planning to predict the facial outcome before surgery is even performed.
3. The surgery itself
Depending on the diagnosis, surgery may involve the upper jaw, the lower jaw, or both. It is performed under general anaesthesia, usually with incisions made inside the mouth so there is no visible scarring on the face. The jawbones are repositioned and held in place with small plates and screws while they heal.
4. Post-surgical orthodontics
Once initial healing has taken place, braces continue for several months to fine tune the bite and make sure the teeth meet precisely in their new, corrected position.
What Recovery Involves
Recovery happens in stages, and most patients can expect a fairly predictable path:
- First week: Swelling, some bruising, and a soft or liquid diet. Pain is managed with prescribed medication and generally eases each day.
- Two to three weeks: Swelling reduces noticeably. Most people feel comfortable returning to work, college or routine activities, though strenuous exercise is still restricted.
- Six weeks: The jawbone has usually healed enough to allow a gradual return to a more normal diet, moving from soft foods toward regular textures.
- Several months: Final bite adjustments continue with braces, and any residual numbness or tightness in the jaw continues to settle.
During recovery, you will be guided on oral hygiene, diet, and jaw exercises to support healing and avoid stiffness. Regular follow-up visits allow the surgical and orthodontic team to track progress and make adjustments as needed.
Getting an Accurate Diagnosis
Not every crooked bite needs surgery, and not every case of facial asymmetry is severe enough to require it. The only way to know for certain is a proper clinical examination along with imaging to assess whether the issue lies in the teeth, the jawbones, or both. For patients in Gurugram dealing with a jaw mismatch that has not responded to braces alone, a combined orthodontic and surgical evaluation is the right next step.
| Stage | Typical Duration | Focus |
|---|---|---|
| Pre-surgical braces | 9 to 14 months | Aligning teeth within each jaw |
| Surgery and hospital stay | 1 to 3 days | Repositioning the jawbone(s) |
| Initial recovery | 2 to 6 weeks | Swelling control, soft diet |
| Post-surgical braces | 3 to 9 months | Final bite correction |

Frequently asked questions
How do I know if I need jaw surgery instead of just braces?
If your upper and lower jaws are mismatched in size or position, braces alone can only move teeth, not the jawbones. A dentist or oral surgeon checks your bite, profile and X-rays to see if the jaws themselves need repositioning. This is usually clear once growth is complete, in the late teens or adulthood.
Is corrective jaw surgery painful?
There is swelling and discomfort for the first week or two, similar to other facial surgeries, and this is managed with prescribed medication. Most patients say the discomfort is manageable and improves steadily each day after the first week.
How long before I can go back to work or college?
Many patients take two to three weeks off from work or studies. Swelling and jaw stiffness continue to settle over the following weeks, but normal talking and light activity usually resume well before full recovery is complete.
Will I need braces after the surgery too?
Yes, in most cases. Braces are used before surgery to align teeth within each jaw, and often continue for some months after surgery to fine tune the bite once the jaws have healed in their new position.
