Does every broken jaw need surgery?
No. Some stable fractures can heal without an operation.
Displaced, unstable, or multiple fractures may need surgical alignment and fixation. Examination and imaging guide the decision.
Craniofacial & Facial Reconstruction
Mandibular Fracture Repair
Mandibular fracture repair treats a broken lower jaw by aligning and stabilizing the bone to support healing, bite alignment, and function.
Will my jaw be wired shut?
Not always.
Plates and screws may stabilize the fracture without prolonged jaw closure. Some repairs use wires or elastic bands to guide or hold the bite.
How urgent is treatment?
A suspected broken jaw needs prompt medical evaluation.
Trouble breathing, severe bleeding, or rapidly increasing mouth or neck swelling requires emergency care.
01 · Overview
Understanding repair of a broken lower jaw
The mandible is the lower jawbone. A fracture may involve the chin, the tooth-bearing portion, the jaw angle, or the joint region near the ear. More than one area can be broken. [1]
Your team checks your bite, teeth, mouth wounds, sensation, and jaw movement. Imaging helps identify the fracture pattern. Breathing problems and other head or neck injuries take priority. [2]
Fracture repair treats an injury. It is different from elective jaw surgery to correct a longstanding bite problem, cosmetic jaw contouring, and treatment of a dislocated jaw without a fracture. [1]
- Primary goal
- Restore jaw alignment and stability
- Treatment setting
- Emergency, hospital, or surgical care
- Stabilization
- May involve plates, screws, wires, or elastics
- Healing
- Usually takes weeks; follow-up confirms progress
Why does my bite matter?
How your teeth meet helps the surgeon assess jaw alignment. Tell the team if your bite feels different from before the injury or if you had missing teeth, dentures, or bite problems beforehand.
Can teeth be affected too?
Yes. Teeth can be loosened or damaged, and a fracture may pass through a tooth socket. The team decides whether affected teeth can be kept and whether separate dental treatment is needed.
02 · Concerns & Goals
What your care team will evaluate
A broken jaw can affect eating, speaking, and how your teeth meet. Treatment depends on the fracture and any related injuries.
A changed bite
Teeth that no longer meet normally may signal displacement. Restoring alignment is a central part of treatment.
Pain and limited movement
Opening your mouth, chewing, or speaking may hurt. The team checks whether the fracture involves the jaw joint.
Numbness
An injury can affect the nerve supplying the lower lip and chin. Sensation may recover slowly and may not fully return.
Wounds and damaged teeth
Cuts inside the mouth, exposed bone, and injured teeth can influence infection risk and the treatment plan.
03 · Options
How the approaches differ
These approaches are not interchangeable. A surgeon experienced in facial trauma recommends treatment based on stability, displacement, bite, teeth, and overall health.
Observation with protected function
Selected stable fractures may heal without surgical fixation.
How it worksThe team monitors alignment and healing while prescribing a suitable diet and limits on jaw use.
May suitSome nondisplaced fractures with an acceptable bite and reliable follow-up.
Main tradeoffAlignment can change, so reassessment is important and surgery may still become necessary.
Closed reduction and jaw fixation
The jaw is aligned without directly exposing the fracture.
How it worksDevices attached to the teeth or jaws use wires or elastics to hold or guide the bite.
May suitSelected fractures that can be aligned and maintained without open surgery.
Main tradeoffEating, oral cleaning, and communication can be harder; emergency instructions are essential when opening is restricted.
Open reduction with internal fixation
Surgery exposes and stabilizes the broken bone.
How it worksThe surgeon aligns the fracture and secures it with plates and screws, often through an incision inside the mouth.
May suitMany displaced, unstable, or complex fractures, depending on their location.
Main tradeoffRisks include infection, nerve injury, hardware problems, and sometimes a visible scar.
External fixation or staged repair
Complex injuries may need temporary or specialized stabilization.
How it worksPins connected to an external frame or a staged surgical plan may be used when immediate internal fixation is unsuitable.
May suitSelected severe injuries with damaged soft tissue, contamination, or bone loss.
Main tradeoffTreatment can involve additional procedures, device care, and a longer recovery.
Jaw-joint fractures and fractures in growing children may need a different balance of stabilization and guided movement. Ask why the proposed approach fits your injury. [1] [2].
Will plates and screws need to come out?
They often remain in place after healing. Removal may be considered for infection, exposure, irritation, or particular growth-related concerns; it is not automatically required.
Will there be a visible scar?
Many fractures can be approached through the mouth, but some require an incision through the skin. Existing injury wounds may also leave scars. Ask where incisions are expected.
04 · Results
What may improve and what may remain
Alignment and bite
Repair aims to bring the jaw and teeth into a functional relationship.
- The original injury, missing teeth, and preexisting bite differences can affect the result.
- A persistent or newly changed bite needs reassessment.
Movement and eating
Function usually returns gradually as healing allows.
- Diet restrictions may continue even when pain improves.
- Guided jaw exercises may be prescribed, particularly when the joint region is involved.
Sensation and appearance
Swelling, contour, and numbness can change over a longer period.
- Nerve symptoms may improve slowly or remain permanent.
- Complex injuries may leave asymmetry or require further reconstructive or dental care.
Recovery depends on fracture severity, associated injuries, and complications. A stable repair does not mean the bone has finished healing. [1]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Your recovery plan depends on the repair and whether jaw opening is restricted. Follow your surgical team's instructions; returning to work is not the same as complete bone healing.
Step 1 · Initial treatment
Treatment day
The team monitors breathing, bleeding, pain, and the bite. Before discharge, you should understand your diet, mouth care, medications, and any fixation-related emergency plan.
Step 2 · First days
Early recovery
Swelling, soreness, and difficulty eating are common. Ask your surgical team whether compresses are appropriate and exactly how to use them.
Step 3 · Following weeks
Healing checks
Visits assess the bite, wounds, fixation, nutrition, and bone healing. Elastics, diet limits, or movement instructions may change based on these findings.
Step 4 · After healing is confirmed
Return to fuller function
Chewing and activity increase with clearance. Some people need dental treatment, movement therapy, or continued monitoring of numbness and jaw-joint symptoms.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
Work or schoolPlanning context: Timing depends on pain, energy, speaking demands, and associated injuries.What affects it: Physical work and jobs with facial-injury risk may require more time away.
EatingPlanning context: A liquid, soft, or no-chew diet may be prescribed. [2]What affects it: Feeling better does not mean the jaw can safely tolerate normal chewing.
Exercise and contact sportsPlanning context: Avoid activities that could reinjure the jaw until cleared. [2]What affects it: Impact risk and confirmed bone healing guide return.
DrivingPlanning context: Ask when driving is safe after anesthesia and during recovery.What affects it: Sedating medicines, pain, limited movement, and other injuries can impair driving.
Ask for activity guidance specific to your fracture, fixation, and daily responsibilities.
Before your procedure
- Share when and how the injury occurred and any other symptoms or injuries.
- Bring a medication list, including blood thinners, supplements, and allergies; do not change prescribed medicines on your own.
- Tell the team about loose teeth, dentures, prior bite problems, and previous jaw treatment.
- Follow the treating team's eating and drinking instructions if anesthesia may be needed; do not delay urgent assessment.
- Discuss smoking, vaping, alcohol use, and support for avoiding nicotine during healing.
- If discharged, arrange help, suitable nutrition, transport, and a clear contact plan for urgent concerns.
What if my jaw is held closed and I vomit?
Before discharge, get a specific emergency plan and training for your fixation device, including whether release tools are needed and how to use them. Do not improvise by cutting wires or removing elastics. If breathing is affected, call 911 immediately and follow the emergency instructions you were taught.
How do I clean my mouth?
Ask for a cleaning method suited to your incisions and fixation. The team may recommend a particular toothbrush or rinse. Do not pull on wires or adjust devices yourself.
06 · Safety
Risks and what your clinician assesses
Swelling, bruising, tenderness, temporary jaw stiffness, and diet limitations are common. Numbness may come from the injury itself. Symptoms should be monitored rather than assumed to be harmless.
Infection
The wound, bone, or fixation hardware can become infected and may require antibiotics or further surgery.
Bleeding and anesthesia complications
Bleeding and reactions to anesthesia can occur. Swelling or associated injuries may also threaten breathing.
Bite misalignment
Teeth may not meet as intended after healing, sometimes requiring additional dental or surgical treatment.
Delayed or incomplete healing
The bone may heal slowly, fail to join, or heal in an unfavorable position.
Nerve or tooth injury
Lower-lip or chin numbness can persist. Injured teeth may need later treatment or removal.
Hardware and movement problems
Plates or screws may loosen, become exposed, or cause irritation. Jaw stiffness, joint pain, or limited opening can persist.
Discuss these risks and your individual health history with your surgeon. [1]
What your clinician assesses
- Fracture location, displacement, stability, and involvement of the jaw joint
- Bite alignment, dental health, mouth wounds, and nerve sensation
- Airway safety and associated head, neck, or facial injuries
- Medical conditions, medications, nicotine use, nutrition, and ability to attend follow-up

08 · Questions
Common questions
Is this the same as corrective jaw surgery?
No. Fracture repair addresses a broken bone after injury. Corrective jaw surgery generally repositions the jaws to treat a longstanding alignment or bite problem.
Will insurance cover treatment?
Injury-related treatment may be covered, but benefits, network rules, and cost sharing vary. Dental treatment may fall under a separate benefit. Ask your insurer and treating facility about your plan.
Can I remove my elastics to eat?
Only if your surgical team has specifically instructed you to do so. Elastics can serve different purposes, and changing them without guidance can affect alignment.
What if my bite feels wrong after repair?
Contact your surgeon promptly rather than waiting for the next routine visit. Do not try to force the jaw into position or adjust the fixation yourself.
