Maybe a dentist pointed out that your lower jaw sits forward, or maybe your teeth were straightened years ago and your bite still doesn’t close the way it should. Either way, the idea of jaw surgery tends to bring up a mix of worry and curiosity. So, when is orthognathic surgery recommended? It’s recommended when the bite problem comes from the jaw bones themselves rather than the teeth, when that mismatch affects chewing, speaking, breathing, or comfort.. If your jaws are still growing, you are probably not a candidate for orthognathic surgery. Most people with crooked teeth or a mild overbite never need it, and this post will help you see where you fall.
In order to have a good bite, your teeth and the jaws within which your teeth sit must coordinate. Braces and Invisalign move teeth through bone, and they’re very good at it. What they can’t do is change how long the lower jaw is, how far forward the upper jaw sits, or how tall the lower face is once growth is done. When the jaws are mismatched by more than the teeth can make up for, orthodontics alone is sometimes not sufficient to compensate for the underlying issue. That’s the point where surgery enters the conversation. The operation repositions the upper jaw, lower jaw, or both, and orthodontic treatment before and after it lines the teeth up so the new jaw position produces a bite that actually fits.
Getting this call right matters, because the two paths look very different. A surgical case usually means a longer plan and a hospital procedure, while a dental case may be finished with braces or aligners alone. At Modern Orthodontics, Dr. Maggie Romao and Dr. Kenneth Cooperman have both served as faculty in the craniofacial orthognathic fellowship at Jacobi Hospital, where they taught other orthodontists how to treat patients who need jaw surgery. Dr. Talia Aboud completed her orthodontic training at Montefiore Medical Center. That background, paired with digital scanning, 3D imaging, and AI-assisted treatment planning, lets our team tell you plainly whether your case is surgical. If it isn’t, we’ll say so. Surgery isn’t the right answer for most people with bite concerns, and an honest evaluation is where every plan starts.

Who Needs Orthognathic Surgery?
Orthognathic surgery is for people whose bite problem is skeletal, large enough to affect function or long-term dental health, and whose jaw growth is complete or nearly complete. All of those usually need to be true before surgery is on the table.
Growth is the piece many families don’t expect. Jaws keep growing through the teen years and sometimes into the twenties, and the lower jaw is often the last to finish. Girls typically reach that point in their mid to late teens, while boys often keep growing into their late teens or early twenties. Operating before growth stops risks the jaw growing again afterward and undoing the correction, so a teenager with a developing underbite may be monitored with periodic imaging until growth settles.
Adults are often the clearest candidates. Some had braces as kids and watched the bite drift back, which can be a sign the jaws were the issue all along. Others have lived with jaw pain, trouble biting through food, or a lower face that looks off-balance and are only now learning it can be corrected. Being in your thirties, forties, or older doesn’t rule you out.
How Do Orthodontists Tell a Jaw Problem from a Tooth Problem?
Orthodontists tell the two apart by measuring the bones directly, not just by looking at how the teeth meet. Two people can have what looks like the same underbite. In one, the lower teeth are tipped forward on a normally sized jaw. In the other, the lower jaw itself is too long. The first is often a braces case, and the second may not be. A thorough evaluation looks at:
- Skeletal relationships on imaging, measuring how the upper and lower jaws sit relative to each other and to the base of the skull
- Tooth angles, to see how far the teeth have already tilted to compensate for the jaw mismatch
- The face in profile and from the front, including lip posture, chin position, and symmetry
- Function, such as how you chew, whether your lips close comfortably at rest, and any jaw joint symptoms
- Growth status for younger patients
Our team uses digital scanning and 3D imaging for this step.
What Jaw Problems Require Surgery?
Surgery is usually considered for jaw discrepancies that are too large to correct by moving teeth, especially when they cause trouble with eating, speech, breathing, or comfort. Common examples include:
- Severe underbite from a lower jaw that’s too long or an upper jaw that’s underdeveloped, often with front teeth that can’t bite together at all
- Severe overbite from a small or set-back lower jaw, sometimes paired with a weak chin and strain when closing the lips
- Skeletal open bite, where the back teeth touch but the front teeth never meet, making it hard to bite into a sandwich or an apple
- Facial asymmetry, where the chin or jaw line shifts to one side because the jaw grew unevenly
- A crossbite involving an upper jaw that’s too narrow for expansion alone to fix in an adult
- Obstructive sleep apnea tied to a small or recessed jaw, in cases where moving the jaws forward can open the airway
Jaw pain by itself is rarely the reason for surgery. TMJ symptoms have many causes, and surgery is typically weighed only when the pain comes alongside a clear skeletal bite problem.
Can Orthodontics Fix Jaw Alignment Without Surgery?
Yes, sometimes. Orthodontics can correct many jaw alignment problems without surgery when the discrepancy is mild to moderate or when the patient is still growing. Which options make sense depends mostly on age.
For children, timing is a real advantage. Growing jaws respond to appliances that guide growth, such as palatal expanders that widen a narrow upper jaw or appliances that help a small lower jaw catch up. That’s one of the main reasons early orthodontic care is worth considering around age seven, since a skeletal problem caught early can sometimes be reduced enough to avoid surgery later.
For adults, the main non-surgical approach is called orthodontic camouflage. Instead of moving the jaws, braces or aligners angle the teeth to hide the mismatch, for example tipping the upper front teeth back and the lower front teeth forward to close a mild underbite. Done well, camouflage can produce a healthy bite and a nice smile. It does have limits:
- It doesn’t change the facial profile, so a prominent or receding chin stays as it is
- Teeth can only tip so far before the gums and supporting bone are put at risk
- Severe cases may relapse after treatment because the teeth are held at strained angles
This is where honest planning pays off. Our full range of orthodontic treatment options lets us recommend camouflage when it will hold up, and surgery only when it won’t.
How Do Orthodontists and Oral Surgeons Work Together?
The orthodontist diagnoses the problem and moves the teeth, and the oral and maxillofacial surgeon repositions the jaws. They plan the case together from the start, because the tooth positions and the jaw movement have to match.
First comes pre-surgical orthodontics with braces or Invisalign, which lines up each arch on its own and often undoes the tilting the teeth used to compensate. Your bite may actually look worse during this phase. That’s expected, since the teeth are being set up for where the jaws will be after surgery, not where they are now. As that phase wraps up, the orthodontist and surgeon review updated records and plan the jaw movements, often with 3D software that previews the result. The surgeon then performs the operation, generally in a hospital, and orthodontic finishing afterward fine-tunes how the teeth fit in their new position.
We handle the orthodontic side and coordinate directly with the oral and maxillofacial surgeons we work with, so you aren’t stuck passing messages between offices. Sometimes your jaw surgery may be covered by your medical insurance rather than your dental insurance; your surgeon’s office will know more about that aspect of your care.
Now Welcoming Patients for Corrective Jaw Surgery Consultations
If you’ve been wondering whether your bite is a tooth problem or a jaw problem, a consultation is the fastest way to find out. Modern Orthodontics is welcoming new patients for jaw surgery evaluations in New York, NY, and if braces or Invisalign alone can do the job, we’ll tell you that too. Call, text, or book online with our Tribeca, Harlem, or Bronx office to get a clear answer about what your bite needs.
