What is the realistic recovery timeline for double jaw surgery — and what does it actually cost?
Orthodontic assessment & pre-surgical braces (12–18 months)
Surgical planning with oral & maxillofacial surgeon
Surgery under general anaesthetic (hospital stay 1–3 days)
Post-surgical recovery & monitoring (weeks 1–6)
Post-surgical braces & final bite refinement (6–12 months)
If your surgeon or orthodontist skipped or rushed any of these stages, that gap in care may have contributed to a poor outcome. Each step exists for a clinical reason.
Understanding double jaw surgery: what it is and what normally happens
Double jaw surgery moves both the upper jaw (maxilla) and the lower jaw (mandible) into new positions. Surgeons cut the bone, reposition it, and fix it in place with titanium plates and screws. The goal is to correct a bite that braces alone cannot fix — including severe underbites, overbites, open bites, and facial asymmetry.
Most people need this surgery because their jaws did not grow in proportion to each other. Some people also have functional problems: difficulty chewing, sleep apnoea, jaw pain, or speech difficulties. For them, this is not cosmetic surgery — it is reconstructive.
Who performs the surgery
An oral and maxillofacial surgeon performs the procedure. This specialist holds both a dental degree and a medical degree. Before surgery, an orthodontist works with the surgeon to align the teeth so they will fit correctly once the jaws move. This teamwork is essential — the orthodontist and surgeon must plan together, not separately.

How common is it? Thousands of Australians undergo orthognathic (jaw) surgery each year. Double jaw surgery is the more complex version, involving both jaws simultaneously.
How long does surgery take? Typically three to five hours under general anaesthetic. Complex cases can take longer.
Hospital stay: Most patients stay one to three nights. Some go home the next day; others need longer monitoring.
Total journey length: From first orthodontic appointment to braces off, most patients spend 18 months to three years in active treatment.
When things start to go wrong: warning signs during recovery
Some discomfort after double jaw surgery is completely normal. Swelling, numbness, and difficulty eating are expected in the first weeks. But certain signs fall outside the range of normal recovery and need prompt attention.
Warning signs that should prompt urgent review:
• Fever above 38.5°C in the first week — this can signal infection at the surgical site
• Increasing pain after day three, rather than gradually improving
• Numbness that does not begin to improve after three months — some nerve numbness is normal early on, but persistent total numbness may indicate nerve damage
• Difficulty breathing or swallowing that worsens rather than improves
• Visible changes to your bite that appear after the initial swelling resolves — the jaws may have shifted
• Plates or screws that feel loose or cause sharp pain under the skin
• Bleeding that does not stop with gentle pressure
Many patients dismiss these signs because they expect recovery to be uncomfortable. Surgeons and their teams carry a responsibility to explain clearly what is normal and what requires a return visit. When that explanation is absent or inadequate, patients can miss a window for early intervention.
A common pattern — where care can break down
Double jaw surgery involves many clinicians across a long period. That complexity creates multiple points where care can fall short. The Australian Commission on Safety and Quality in Health Care identifies communication failures between treating teams as one of the most common sources of preventable harm in surgical care.
Inadequate pre-surgical planning
The orthodontist and surgeon must coordinate closely before surgery. When either clinician plans in isolation, the teeth and jaws may not align correctly after the procedure. Poor planning at this stage can mean the surgery achieves the wrong result — and a second operation becomes necessary.
Failure to obtain proper informed consent
Patients have a right to understand the specific risks of double jaw surgery before agreeing to it. Those risks include permanent nerve damage, relapse of the jaw position, infection, and the possibility of needing revision surgery. When a surgeon does not explain these risks in plain terms, the patient cannot make a genuinely informed decision.
Inadequate post-operative monitoring
The first two weeks after surgery are critical. Swelling can mask problems. Infection can develop quickly. When surgical teams discharge patients without clear written instructions, or fail to schedule timely follow-up appointments, early complications go undetected.
Dismissing reported symptoms
Some patients report persistent numbness, bite changes, or pain at follow-up appointments — and clinicians attribute these to normal healing. When a clinician dismisses a symptom that later proves to indicate a real problem, the delay in treatment can worsen the outcome significantly.
Failure to refer for revision
Not every surgeon has the experience to manage complex complications. When a complication exceeds a surgeon’s expertise, the appropriate response is referral to a more specialised centre. Delaying that referral — or not making it at all — can allow a fixable problem to become permanent.
Why this matters legally
Every surgeon and orthodontist who treats you owes you a duty of care. That phrase — duty of care — means they are legally required to provide treatment that meets the standard a competent practitioner in their field would provide. When care falls below that standard and causes you harm, the law may recognise that as medical negligence.
Not every bad outcome is negligence. Double jaw surgery carries real risks, and some complications occur even when a surgeon does everything correctly. The legal question is not whether something went wrong — it is whether the clinician’s actions fell below what a reasonable, competent surgeon would have done in the same situation.
For a broader explanation of how this area of law works in Australia, Reframe Legal — Medical Negligence provides a plain-English overview.
Temporary numbness lasting up to three months after surgery — this is a known and disclosed risk of the procedure
Permanent nerve damage that a surgeon failed to investigate after the patient reported persistent numbness at multiple follow-up appointments
This is a general educational framework only. Each case is assessed on its individual facts.
When double jaw surgery may amount to medical negligence
Several specific failures in double jaw surgery care can cross the line from an unfortunate outcome into a legally recognisable breach of the standard of care.
Surgical planning errors. If the surgeon repositioned your jaw to coordinates that the joint planning process should have identified as incorrect, and your bite is now worse than before surgery, that planning failure may constitute a breach.
Undisclosed risks. If your surgeon did not tell you that permanent nerve damage was a real possibility — and you experienced it — you may not have given truly informed consent. Under NSW law, informed consent requires that a clinician disclose all material risks: those a reasonable patient in your position would want to know about.
Delayed treatment of infection. When a patient reports signs of infection and the surgical team dismisses those signs without investigation, any resulting harm from that delay may be attributable to the team’s failure to act.
Jaw relapse from inadequate fixation. If the plates and screws the surgeon used were insufficient for your bone structure, and your jaw moved back toward its original position, that technical failure may be actionable.
The NSW Civil Liability Act 2002 governs how courts assess these claims in New South Wales. That Act sets out the standard a clinician must meet and the way courts measure whether a breach caused harm.
When harm becomes long-term or permanent
For most patients, double jaw surgery produces a good outcome. But when something goes wrong and the problem goes unaddressed, harm can compound over time.
Physical consequences
Permanent nerve damage can leave a patient with numbness or altered sensation in the lips, chin, cheeks, or tongue for life. Jaw relapse — where the bones shift back — can undo the surgical result entirely and require a second operation. Chronic pain in the jaw joint (temporomandibular joint, or TMJ) can develop when the surgical result is not properly aligned.
Psychological consequences
Many patients undergo this surgery after years of self-consciousness about their appearance or function. When the outcome is poor, the psychological impact can be severe. Anxiety, depression, and social withdrawal are documented consequences of failed jaw surgery outcomes. Some patients describe the experience as a loss of trust in medical care that affects every subsequent health interaction.
Financial consequences
Revision surgery is expensive. Patients who need a second procedure face another round of pre-surgical orthodontics, another hospital admission, and another extended recovery. Many also lose additional income during a second recovery period. Those costs accumulate on top of what the patient already spent on the first procedure.
What compensation can cover in double jaw surgery cases
NSW compensation in a medical negligence case can cover several categories of loss. Those categories include pain and suffering, lost income during recovery and beyond, the cost of revision surgery, ongoing treatment costs, and the cost of care provided by family members.
| Level of harm | Typical compensation range |
|---|---|
| Moderate injury | $50,000–$150,000 |
| Serious injury | $150,000–$500,000 |
| Severe / life-changing injury | $500,000+ |
Each case is assessed on its own facts. These figures are general ranges only. A patient with permanent nerve damage and the need for revision surgery will sit in a different range than a patient who experienced a delayed diagnosis of infection that resolved fully after treatment.
Time limits apply in NSW. Generally, a person has three years from the date they knew — or ought reasonably to have known — that they had a potential claim. For some patients, that clock starts running from the date of surgery. For others, it starts later, when the full extent of the harm became apparent. Seeking legal advice early protects your position.

You don’t need certainty to understand your position
Most people who experienced a poor outcome from double jaw surgery spend months — sometimes years — wondering whether what happened to them was normal. That uncertainty is understandable. Recovery is long, clinicians speak in reassuring terms, and it is hard to know what the standard should have been.
Legal clarity does not require you to be certain something went wrong. It requires only that you gather the facts and have them examined by someone who understands both the clinical and legal standards. A lawyer with experience in surgical negligence can review your records, identify where the care may have fallen short, and tell you honestly whether a claim is worth pursuing.
Informed consent is one of the most commonly misunderstood areas of surgical law. Many patients do not realise that signing a form is not the same as giving legally valid consent. For more on this, see Reframe Legal — Informed Consent and Medical Negligence.

About the lawyer behind this article
Dr Rosemary Listing is a NSW lawyer with a PhD focused on medical negligence. Her academic and clinical background gives her an unusual ability to read surgical records, understand operative notes, and identify where a clinical decision departed from accepted practice.
Dr Listing has worked on cases involving oral and maxillofacial surgery, including patients who experienced jaw relapse, permanent nerve damage, and failed outcomes following inadequate pre-surgical planning. Her experience in this area means she understands both the technical complexity of the surgery and the long recovery journey patients endure.
A consistent finding in surgical negligence cases is that harm rarely comes from the surgery alone. More often, harm comes from what happened before — inadequate planning, absent consent discussions — or from what happened after, when clinicians dismissed reported symptoms rather than investigating them.
Clients who approach Dr Listing are not always seeking blame. Many simply want to understand what happened to them and whether the care they received met the standard they were owed. That clarity, in itself, has value.
Dr Listing’s role is to examine the facts of each case against the clinical standard, identify where that standard was or was not met, and give clients an honest assessment of their position.
