How long does swelling last after jaw surgery?

The most dramatic swelling peaks around days 3–5 and begins to noticeably reduce by weeks 2–3. However, residual puffiness can persist for 3–6 months as deep tissue continues to heal.

Will I lose weight after jaw surgery?

Weight loss of 3–7 kg is common in the first month due to the liquid and pureed diet. Your surgical team will guide you on calorie-dense liquids to minimise muscle loss during this period.

When does numbness in the chin resolve after orthognathic surgery?

Numbness or altered sensation in the chin, lower lip, and cheeks is normal and results from nerve stretching during repositioning. Most patients see significant return of sensation by months 3–6, though full resolution can take up to 12–18 months.

Can I go back to work after jaw surgery?

Light desk work is typically possible by weeks 2–3, depending on pain levels and energy. Physical or demanding roles may require 4–6 weeks off. Discuss your specific situation with your surgeon before planning a return date.

Do I need orthodontics after jaw surgery?

Yes. Orthognathic surgery is almost always part of a combined orthodontic-surgical treatment plan. Post-surgical orthodontics fine-tunes the bite alignment after the jaws have healed and typically continues for 6–12 months after surgery.

Day-by-Day After Jaw Surgery (Orthognathic): Recovery Guide

Orthognathic surgery — the surgical repositioning of the upper jaw (maxilla), lower jaw (mandible), or both — is among the most involved procedures a patient can undergo in the dental and oral health field. For Townsville residents pursuing this treatment, surgery typically takes place at a regional hospital or through referral to a Brisbane or Cairns maxillofacial unit, followed by the full recovery period back home. Understanding each phase of that recovery helps patients and their families prepare practically and emotionally for what lies ahead.

The timeline is longer than many patients expect. Unlike a tooth extraction or even wisdom teeth removal, orthognathic recovery is measured in months, not days. Each stage has distinct challenges — from managing a liquid diet in week one to regaining full mouth opening by month three. This guide walks through the recovery week by week and month by month, with clear markers for what is normal and when to contact your surgeon.

Week 1: Hospital and the First Days Home

Most patients remain in hospital for 1–3 days after orthognathic surgery. During this time, pain is managed via intravenous medication, and the surgical and nursing team monitors swelling, airway, and fluid intake.

Swelling and bruising are dramatic in the first 72 hours. The face may appear unrecognisable due to oedema, and bruising often tracks down the neck and chest. This is expected and not a sign of complication. Ice packs applied in cycles during the first 48 hours can help reduce severity.

Nutrition is the most demanding early challenge. With the jaws immobilised or the mouth nearly unable to open, patients take in all calories through a syringe, a wide-bore straw, or a gap between back teeth if elastics allow a small opening. Targets to aim for each day:

At least 1,500–2,000 calories from liquid sources
High-protein options such as blended legumes, protein shakes, and full-fat milk
Electrolyte drinks to replace what is lost through limited intake and medication

Oral hygiene begins immediately. Using a soft toothbrush on accessible surfaces and a chlorhexidine rinse prevents infection around surgical sites. Your surgical team will demonstrate the correct technique before discharge.

Weeks 2–3: Still Substantial, Slowly Shifting

By the end of the first week and into week two, patients are home and the reality of a slower pace sets in. Swelling has not resolved — it typically reaches 60–70 per cent reduction by week two but remains noticeable to others and uncomfortable to the patient.

Jaw fixation via wire ties or orthodontic elastic bands maintains the new bite position. Elastics are common because they allow some controlled opening while preventing the muscles from pulling the repositioned bone out of alignment. Patients are typically given a wire cutter or scissors in case of emergency (nausea requiring immediate mouth opening), but these are not to be used casually.

Weight loss is common and should be monitored. A loss of 3–7 kg across the first month is frequently reported. If energy levels drop sharply or dizziness occurs, consult your surgeon about adjusting calorie targets.

Activities to avoid during this stage:

Blowing the nose forcefully (risk of air entering the sinuses at the surgical site)
Strenuous physical activity or bending forward
Any contact sport or activity that risks a blow to the face
Chewing or biting, regardless of how minor it may seem

Most patients can return to light seated work by week 2–3 if pain and fatigue allow, though concentration is often affected by medication and disrupted sleep.

Months 1–2: Jaw Stiffness and the Return to Soft Food

Around weeks 4–6, elastics are progressively lightened or removed during the day, and physiotherapy exercises begin. The goal of these exercises is to restore mouth opening and reduce the stiffness that develops from weeks of immobilisation.

Physiotherapy exercises are prescribed by your surgeon or an orofacial physiotherapist and typically include:

Controlled mouth-opening stretches, repeated multiple times daily
Lateral jaw movement exercises to restore sideways range
Chin and lip massage to encourage nerve recovery and reduce tightness

Diet progression moves from liquids to pureed food, then to soft food. Milestones by food texture:

Phase	Approximate Timing	Examples
Full liquid	Weeks 1–3	Shakes, soups, blended meals
Pureed	Weeks 4–6	Mashed potato, soft scrambled egg, yoghurt
Soft food	Weeks 6–10	Soft pasta, fish, well-cooked vegetables
Normal (gradual)	Month 3 onwards	Introduced slowly, surgeon-guided

Facial numbness — particularly in the chin, lower lip, and cheeks — is present for most patients during this period. This results from nerve stretching when the bone segments were repositioned. Sensation typically begins returning by month 3, though some areas may take 12–18 months to fully resolve.

Months 3–6: Bite Settling and Retention Orthodontics

By the three-month mark, most patients notice a meaningful shift in how normal life feels. Energy has returned, diet is close to typical, and the face looks recognisably like themselves again, though minor asymmetry from residual swelling may still be present.

Final bite settling occurs as bone remodels and muscles adapt to their new length and position. Minor bite discrepancies noted at this stage are usually addressed through orthodontic adjustment rather than surgical revision.

Post-surgical orthodontics — the continuation of braces or aligners after surgery — fine-tunes tooth alignment to the new jaw position. This phase typically runs for 6–12 months and concludes with retainers. Patients who began their treatment journey with orthodontics before surgery will be familiar with this stage.

Long-term follow-up with your maxillofacial surgeon, orthodontist, and general dentist is important. Regular dental checks ensure the teeth and supporting structures remain healthy throughout the extended treatment period.
