Injuries to the mouth
and facial fractures

A tooth that is knocked out, broken or loosened, or a blow that breaks the jaw, the cheekbone or the eye socket: acting in the first minutes, with the right specialist, changes the outcome.

What does maxillofacial trauma cover?

It ranges from dental injuries—teeth that are fractured, displaced or knocked out—to fractures of the facial bones: jaw, upper jaw, cheekbone, nose and eye socket. The most common causes are falls, road accidents, sports and assaults.

Displaced fractures are treated with surgery: the fragments are put back in place and fixed with titanium miniplates and screws. That way the bite returns to its position and the bone heals without shifting. When trauma, a cyst or a tumour leaves a bone defect, facial reconstruction restores it with grafts or custom-designed implants.

Dr. Rodríguez is a maxillofacial surgeon at the Trauma Hospital of Costa Rica's National Insurance Institute (INS) and was chief resident at the «Victorio de la Fuente Narváez» Trauma Hospital (IMSS) in Mexico City.

First aid: a knocked-out tooth
  • 01Hold it by the crownthe white part; do not touch the root.
  • 02If it is dirty, rinse it for a few secondsin milk, saline or saliva, without scrubbing.
  • 03Try to put it back in placeand bite gently on a handkerchief; if you cannot, keep it in milk.
  • 04Get care immediatelyideally within the first hour.

Baby teeth are not put back in: keep the tooth and see us anyway.

How it works

A jaw fracture, in three steps

01Step 1/3

The fracture

A blow breaks the body of the jaw between the teeth. If the fragments shift, a step appears and the bite no longer fits.

Reduction and fixation

In the operating room the fragments are put back in place and fixed with titanium miniplates and screws, often from inside the mouth.

About six weeks later

The bone heals in the right shape and the bite fits again. The plates usually stay for good and are not noticeable.

Options

From the tooth to the facial bones.

  • 01Knocked-out tooth

    Replantation and splint

    The tooth is repositioned and joined to its neighbours with a flexible splint for about two weeks; the tooth's nerve is then monitored.

  • 02Fractured or displaced tooth

    Repositioning and restoration

    Depending on the fracture, the tooth is repositioned, splinted or restored; sometimes it needs a root canal.

  • 03Jaw, upper jaw, cheekbone, eye socket

    Reduction and fixation

    In the operating room the fragments are put back and fixed with titanium miniplates, often from inside the mouth.

  • 04Bone defects

    Facial reconstruction

    Bone grafts or custom implants, planned on a CT scan, to restore what was lost.

Step by step

From the emergency to healing.

  1. 01Emergency
    Stabilise and diagnose

    Examination, pain control and a CT scan to see every fracture line.

  2. 02Hours–days
    Surgery

    Reduction and fixation with plates, under general anesthesia in hospital.

  3. 03Weeks 1–6
    Soft diet

    The bone heals: soft food, no forceful chewing.

  4. 04Week 6 onward
    Check-ups

    Review of the bite, mouth opening and sensation.

After a jaw fracture

What to expect

  1. Days 1–3

    Swelling and discomfort peak; cold packs and head raised.

  2. Weeks 1–2

    Discomfort eases; liquid or soft diet.

  3. Weeks 2–6

    Soft diet without forceful chewing; careful hygiene.

  4. Week 6+

    The jaw has usually healed; gradual return to a normal diet.

Do not wait

When to seek care promptly

  • Difficulty breathing or swallowing
  • Bleeding that will not stop
  • Double vision after a blow to the face
  • The bite does not close as before
  • Reviewing the 3D reconstruction before planning
  • Dr. Rodríguez and his team in the operating room
  • The instruments ready on the tray during surgery
Frequently asked

What patients ask before deciding.

Hold it by the crown, rinse it for a few seconds in milk or saline if it is dirty and try to put it back. If you cannot, keep it in milk and get care immediately—ideally within the first hour.
Often, yes—especially if it is replanted quickly or kept in milk. After 60 minutes dry, the outlook drops sharply.
Pain when biting, a bite that no longer fits, difficulty opening the mouth, numbness of the lip or chin and swelling. A CT scan confirms it.
No. Fractures that are not displaced sometimes only need a soft diet and check-ups. Displaced ones are operated on so the bone heals in place.
They usually stay for good and are not noticeable; they are only removed if they cause discomfort.
About six weeks for the bone to heal, with a soft diet during that time. Full recovery can take a little longer.
