If you’ve been told you might need jaw surgery, the first reaction for most people is some version of: “How long does this take, and what exactly am I signing up for?” Those are fair questions. Orthognathic surgery is a significant commitment, and the timeline from your first consultation to full recovery is longer than most patients initially expect. But it’s also more manageable than it sounds, especially when you understand each phase before you get there.
At Greeley Orthodontics in Kennett Square, PA, Dr. Greeley has extensive experience working collaboratively with oral surgeons to coordinate jaw surgery cases across Chester County and the surrounding communities. This guide walks through the full patient journey so you know what to expect at every step.
What Is Orthognathic Surgery and Who Needs It?
Orthognathic surgery corrects jaw problems that braces alone cannot fix. When the upper jaw, lower jaw, or both are significantly misaligned, the result affects more than how your smile looks. It can affect how you bite, how you chew, how you breathe, how you speak, and in some cases, how well you sleep.
Common reasons patients pursue orthognathic surgery include:
- Severe overbite or underbite that orthodontic treatment alone cannot correct
- Open bite, where the upper and lower front teeth don’t make contact when the mouth is closed
- Facial asymmetry caused by uneven jaw growth
- Chronic jaw pain or TMJ issues related to jaw position
- Obstructive sleep apnea linked to jaw structure
- Difficulty chewing or biting due to how the teeth and jaws meet
Not every patient with these concerns needs surgery. But for those who do, the combination of orthodontic treatment and surgical correction produces results that neither approach achieves alone.
Phase One: The Initial Consultation
What Happens at Your First Appointment
The process begins with a thorough evaluation. At Greeley Orthodontics, that means a comprehensive assessment of your teeth, bite, and jaw relationships. Dr. Greeley will review your dental and medical history, take records including X-rays and photographs, and assess how your upper and lower jaws relate to each other and to your facial structure.
This appointment isn’t just diagnostic. It’s also a conversation. You’ll discuss your concerns, your goals, and whether surgery is actually the right path for your specific situation. Not every patient who walks in expecting surgery ends up needing it. And not every patient who hasn’t considered surgery will leave without it on the table.
Coordinating With an Oral Surgeon
Orthognathic surgery is always a team effort. The orthodontist and the oral surgeon work together from the beginning to plan treatment, not independently. Dr. Greeley is recognized for her collaborative approach with oral surgeons, which matters because the timing and sequencing of orthodontic preparation directly affects what the surgeon can achieve.
You will likely be referred to an oral and maxillofacial surgeon for a separate consultation early in the process. Both providers will review your records together and develop a coordinated treatment plan.
Phase Two: Pre-Surgical Orthodontics (12 to 18 Months)
This is the phase that surprises most patients. Before surgery can happen, you need braces. And you’ll wear them for a significant period of time before the surgical date is ever scheduled.
Why Braces Come Before Surgery
This feels counterintuitive. Many patients assume the surgery happens first, then the braces fix whatever is left. The reality is the opposite.
Pre-surgical orthodontics move the teeth into the positions they will occupy after the jaws are repositioned. Without this step, the teeth may look better during treatment but end up in the wrong position once the jaw is where it needs to be. The braces are essentially preparing your teeth for a new jaw position, not the jaw position you currently have.
This phase often makes the bite feel worse before surgery. That’s expected. It means treatment is progressing correctly.
What to Expect During Pre-Surgical Orthodontics
- Regular adjustment appointments every 6 to 8 weeks
- Possible tooth extractions in some cases, depending on crowding and the surgical plan
- Ongoing records and imaging as treatment progresses to monitor jaw position
- Communication between your orthodontist and surgeon to confirm readiness for surgery
The length of this phase varies. Most patients need 12 to 18 months of pre-surgical orthodontic preparation, though complex cases can extend beyond that.
Phase Three: Surgical Planning and Preparation
Records and Imaging Before Surgery
Once your orthodontist and surgeon agree that your teeth are ready, a final set of records is taken. This typically includes a 3D cone beam CT scan, updated photographs, dental impressions or digital scans, and detailed measurements of your jaw and facial structure.
These records are used to plan the surgery with precision. Many oral surgeons use computer-assisted planning to simulate the surgical movements before the procedure, which allows the team to anticipate the outcome and make adjustments to the plan before a single incision is made.
Pre-Surgical Medical Clearance
Because orthognathic surgery is performed under general anesthesia, you’ll also need medical clearance from your primary care physician or an internist. Blood work, an EKG if indicated by age or health history, and a review of any medications that need to be paused before surgery are all part of this step.
Your surgeon’s office will provide a detailed pre-operative checklist. Follow it carefully. Procedures like stopping blood thinners, adjusting certain supplements, and fasting before surgery are not optional steps.
Preparing Your Home for Recovery
This is worth doing before surgery, not after. You’ll be on a liquid and soft food diet for several weeks post-surgery, so stocking your kitchen in advance makes the first week significantly easier. Think protein shakes, broth, applesauce, yogurt, smoothie ingredients, and soft foods that require no chewing.
Other practical preparations include:
- Arranging at least one week off work or school
- Lining up a caregiver for the first few days post-surgery
- Preparing a recovery area with pillows for elevation, ice packs, and entertainment
- Filling prescriptions in advance so they’re ready when you get home
Phase Four: The Surgery Itself
What Happens During Orthognathic Surgery
The surgery is performed in a hospital or surgical center under general anesthesia. Depending on whether one jaw or both jaws are being repositioned, the procedure typically takes between two and five hours.
Incisions are made inside the mouth, so there are no visible facial scars in most cases. The surgeon repositions the jaw bones and secures them with small titanium plates and screws that remain in place permanently. These hardware pieces are not felt after healing and do not trigger metal detectors.
Hospital Stay
Most patients spend one night in the hospital following surgery. Some cases, particularly double jaw surgery, may require a two-night stay. Your surgical team will advise you based on your specific procedure.
What You’ll Feel Immediately After
Swelling is significant, and it peaks around 72 hours post-surgery before it begins to subside. Numbness in the lips, chin, and cheeks is common and expected due to the proximity of sensory nerves to the surgical sites. Most of this numbness resolves over weeks to months as the nerves recover.
Pain is typically well-managed with prescribed medication. Most patients describe significant discomfort rather than severe pain, especially once swelling peaks and begins to decrease.
Phase Five: Early Recovery (Weeks One Through Four)
The First Week
The first week is the hardest. Swelling is at its peak, eating requires effort and planning, and fatigue is significant. Most patients are not back to normal activity for at least seven to ten days.
You will likely be on a full liquid diet for the first two weeks. That means nothing that requires chewing whatsoever. Protein shakes, smoothies, soups blended smooth, and drinkable yogurt become the core of your diet. Getting enough protein during this phase is important for healing, so planning meals in advance pays off.
Oral hygiene needs to continue carefully. Your surgeon will provide specific instructions for rinsing and cleaning around the surgical sites without disrupting healing tissue.
Weeks Two Through Four
Swelling continues to decrease gradually through this period. Most patients transition to a soft food diet around the two-week mark, depending on how healing is progressing. Scrambled eggs, soft pasta, mashed potatoes, fish, and similar textures become available.
Energy levels improve steadily. Most patients return to desk work or school within one to two weeks, though physical exertion should be avoided for at least four to six weeks.
Phase Six: Post-Surgical Orthodontics (Six to 12 Months)
Once the jaw has healed sufficiently, usually around six to eight weeks after surgery, post-surgical orthodontic treatment begins. This phase fine-tunes the bite and positions the teeth precisely within the newly aligned jaw.
Post-surgical orthodontics typically takes six to twelve months. The braces come off once your orthodontist confirms the bite is fully optimized and the teeth are in their final positions.
Retainers After Treatment
After braces are removed, retainers are required to maintain the results. This is true for all orthodontic patients, and it’s especially important after orthognathic surgery because the investment in treatment is significant. Your retainer protocol will be outlined by Dr. Greeley at the time of debanding.
Total Timeline: What to Realistically Expect
The full orthognathic surgery process from consultation to completed post-surgical orthodontics typically spans two to three years for most patients. Here’s a simplified view:
- Consultation and planning: 1 to 3 months
- Pre-surgical orthodontics: 12 to 18 months
- Surgical preparation and procedure: 1 to 2 months
- Early recovery: 4 to 6 weeks
- Post-surgical orthodontics: 6 to 12 months
That’s a real commitment. Patients who go into the process with a clear understanding of the timeline tend to handle each phase significantly better than those who expect a faster path.
FAQ: Orthognathic Surgery Patient Questions
Is orthognathic surgery painful?
Most patients describe the immediate post-surgical period as uncomfortable rather than severely painful, largely because swelling is the dominant sensation. Pain is managed with prescribed medication during the first week. By the second week, most patients have transitioned to over-the-counter options as needed. Discomfort decreases steadily as swelling resolves over the following weeks.
Will insurance cover orthognathic surgery?
Coverage varies significantly by insurance plan. When jaw surgery is medically necessary, which includes cases involving sleep apnea, functional bite problems, or documented medical need, many medical insurance plans provide coverage for the surgical portion of treatment. Orthodontic insurance may cover part of the pre- and post-surgical orthodontic care. Your orthodontist and oral surgeon’s offices can help you navigate the insurance and pre-authorization process before treatment begins.
How long does swelling last after jaw surgery?
Initial swelling peaks around 72 hours after surgery and then begins to decrease gradually. Most of the visible swelling resolves within four to six weeks. Residual subtle swelling can persist for three to six months in some patients, particularly after double jaw surgery. The final result of the surgery is not fully visible until swelling has completely resolved.
Can I go back to work or school after orthognathic surgery?
Most patients return to desk work or school within one to two weeks after surgery. Physical activity, sports, and strenuous exertion should be avoided for at least four to six weeks. Your oral surgeon will clear you for increased activity based on how your healing progresses at follow-up appointments.
Why do I need braces before jaw surgery if surgery is moving the jaw?
Pre-surgical orthodontics position your teeth in alignment with where your jaw will be after it’s repositioned, not where it is now. Without this preparation, the teeth would be in the wrong position relative to each other after the jaw moves. The braces prepare the teeth for the post-surgical jaw position so that the bite functions correctly once healing is complete.
