What Is Jaw Surgery?
Jaw surgery, also called orthognathic surgery, is a procedure that repositions the upper jaw, lower jaw, or both to correct skeletal misalignment. An oral and maxillofacial surgeon performs this surgery in a hospital or surgical center under general anesthesia.
Jaw surgery is typically recommended when orthodontic treatment alone cannot correct the problem. Conditions that may require jaw surgery include a significantly recessed or protruding jaw, open bite (front teeth that do not meet when you close your mouth), facial asymmetry, and obstructive sleep apnea caused by jaw structure. The goal is to improve how the teeth fit together (occlusion) and how the jaw functions.
Types of Jaw Surgery
- Upper jaw surgery (Le Fort I osteotomy): The surgeon repositions the upper jaw (maxilla) by making cuts in the bone above the teeth and moving the entire upper jaw forward, backward, up, or down. This procedure corrects open bites, crossbites, and upper jaw deficiency.
- Lower jaw surgery (bilateral sagittal split osteotomy): The surgeon splits the lower jaw (mandible) on both sides behind the molars and repositions the front portion forward or backward. This corrects a recessed or protruding lower jaw.
- Dual-jaw surgery (bimaxillary osteotomy): Both the upper and lower jaws are repositioned in the same operation. This is the most involved type of jaw surgery and is used for complex cases where both jaws contribute to the misalignment.
- Genioplasty (chin surgery): The chin bone is cut and repositioned to improve facial balance. This is sometimes performed alongside upper or lower jaw surgery.
Jaw Surgery Cost Breakdown
The total jaw surgery cost includes several components. Understanding each one helps you plan financially and have informed conversations with your surgeon's office and insurance provider.
Surgeon Fees
The oral surgeon's fee for jaw surgery typically ranges from $5,000 to $15,000, depending on whether one or both jaws are being operated on. Dual-jaw surgery is more complex and takes longer, so it costs more than a single-jaw procedure. Surgeon fees vary by geographic region, with major metropolitan areas generally charging more. Costs vary by location and provider.
Hospital and Anesthesia Fees
Jaw surgery is performed under general anesthesia in a hospital or accredited surgical center. Hospital facility fees typically range from $10,000 to $20,000, covering the operating room, nursing staff, equipment, and an overnight stay (most jaw surgery patients stay one night). Anesthesia fees add $2,000 to $4,000 depending on the length of the procedure. A single-jaw surgery usually takes 1 to 2 hours; dual-jaw surgery takes 3 to 5 hours.
Orthodontic Treatment Costs
Most jaw surgery patients need 12 to 18 months of orthodontic treatment (braces or clear aligners) before surgery to position the teeth correctly, and 6 to 12 months of orthodontics after surgery for final alignment. Orthodontic treatment adds $5,000 to $8,000 to the overall cost. Some orthodontists offer a combined surgical-orthodontic treatment fee.
Total Cost by Surgery Type
These ranges include surgeon, hospital, and anesthesia fees but not orthodontic treatment. Costs vary by location, provider, and case complexity.
- Upper jaw surgery (Le Fort I): $20,000 to $30,000
- Lower jaw surgery (BSSO): $20,000 to $30,000
- Dual-jaw surgery: $25,000 to $40,000 or more
- Genioplasty alone: $3,000 to $10,000
Insurance Coverage for Jaw Surgery: Medical vs. Dental
One of the most important things to understand about jaw surgery cost is that medical insurance, not dental insurance, typically covers the procedure. Dental insurance generally does not cover jaw surgery because it is classified as a surgical procedure requiring hospital care.
Medical insurance plans often cover jaw surgery when there is a documented functional impairment. Functional reasons for jaw surgery include inability to chew properly, chronic jaw pain from skeletal discrepancy, obstructive sleep apnea caused by jaw anatomy, and significant bite problems that affect speech or breathing. Your oral surgeon's office will typically submit a pre-authorization request to your medical insurance with clinical records, imaging, and a letter of medical necessity.
If your insurance approves the surgery, your out-of-pocket cost depends on your deductible, copay, and coinsurance. Many patients pay $3,000 to $10,000 out of pocket after insurance. If the surgery is classified as purely cosmetic (for appearance only, with no functional impairment), insurance is unlikely to cover it.
Tips for Getting Insurance Approval
- Ask your oral surgeon's office about their experience with insurance pre-authorization. Experienced practices know how to document medical necessity effectively.
- Get a referral from your orthodontist documenting that orthodontic treatment alone cannot correct the problem.
- If you have sleep apnea, a sleep study showing the condition is related to jaw anatomy strengthens the case for coverage.
- Request a pre-determination (not just a pre-estimate) from your insurance company before scheduling surgery.
- If your claim is denied, ask your surgeon's office to help with the appeal process. Many initial denials are overturned on appeal.
What to Expect: Jaw Surgery Recovery
Jaw surgery recovery is a significant commitment. Understanding the timeline helps you plan time off work, arrange meals, and set realistic expectations.
Weeks 1-2: Initial Recovery
Swelling peaks around days 2 to 4 and gradually decreases over the following weeks. Your jaw will be held in position with small titanium plates and screws (these are permanent and do not need to be removed). Most patients are on a liquid-only diet for the first 1 to 2 weeks. Pain is managed with prescription medication. You will not be able to open your mouth wide, and some surgeons use rubber bands or elastics to guide your bite during healing.
Weeks 3-6: Gradual Return to Activity
Most patients return to work or school within 2 to 4 weeks, depending on the physical demands of their job. You will transition from a liquid diet to soft foods. Swelling continues to decrease but may not fully resolve for 2 to 3 months. Numbness in the lower lip, chin, or upper lip is common during this period and usually improves over the following months.
Months 3-6: Full Bone Healing
The jawbone takes 3 to 6 months to fully heal and stabilize. During this time, you will continue orthodontic treatment to fine-tune your bite. Most patients can return to all normal activities, including exercise and eating regular foods, within 3 months. Some residual numbness may persist for 6 to 12 months, and in rare cases, a small area of permanent numbness can occur.
When to See an Oral Surgeon About Jaw Surgery
If your orthodontist or general dentist has mentioned that your bite problem may require surgery, the next step is a consultation with an oral and maxillofacial surgeon. Signs that jaw surgery may be needed include a bite that orthodontics alone cannot correct, chronic jaw pain from skeletal misalignment, difficulty biting or chewing due to how the jaws fit together, obstructive sleep apnea related to jaw anatomy, and facial asymmetry that affects function.
During a consultation, the oral surgeon will evaluate your jaw structure with clinical examination and imaging (typically a CBCT scan and cephalometric X-rays), discuss whether surgery is appropriate, explain the expected outcomes, and provide a cost estimate. Many patients get consultations with two or three surgeons before making a decision.
