What Causes a Broken Jaw?
The jaw, or mandible, is one of the strongest bones in your face, but it is still vulnerable to force. Some of the most common causes of a broken jaw include:
Car accidents
Physical assault or fights
Sports injuries, especially in contact sports
Slips or falls that impact the chin or side of the face
Workplace injuries, especially in construction or factory environments
Even something as simple as falling on a hard surface can cause the jaw to fracture if the impact is in the right spot.
Common Signs Your Jaw May Be Broken
A broken jaw does not always present with dramatic symptoms. Sometimes the pain and swelling develop slowly. Other times, the symptoms are immediate and severe. Here are the key signs to look for:
1. Severe jaw pain
Persistent or worsening pain in the jaw, especially after an impact, is often the first sign. The pain may increase when trying to speak, chew, or open your mouth.
2. Swelling and bruising
Swelling around the jawline or cheeks, especially on one side, is a common symptom. Bruising may appear under the tongue, along the jawline, or around the ears.
3. Difficulty opening or closing your mouth
If it feels like your mouth will not open all the way, or your jaw won’t close properly, that could be a sign of a fracture or dislocation.
4. Misaligned bite
A clear warning sign is if your upper and lower teeth no longer line up when you close your mouth. This can make chewing uncomfortable or impossible.
5. Loose or damaged teeth
A broken jaw can cause teeth near the fracture site to loosen or shift. Some patients may also experience bleeding from the gums or tongue.
6. Numbness in the lower lip or chin
Nerve damage near a jaw fracture can cause numbness or tingling in the lower part of the face, especially the chin or lower lip.
7. Popping or clicking sounds
If your jaw makes odd sounds when moving, especially if it’s paired with pain, it could mean the joint or bone is not aligned properly.
8. Facial deformity or asymmetry
In more serious fractures, the jawline may appear crooked, sunken, or uneven. You may also see a shift in the shape of your smile or cheekbones.
What to Do If You Suspect a Broken Jaw
If you or someone else may have a fractured jaw, it is important to act quickly and carefully. Follow these steps:
Do not try to move the jaw
Avoid opening or closing your mouth forcefully. Movement could worsen the injury.Apply a cold compress
Use a cold pack or a clean cloth with ice to reduce swelling and pain. Do not apply ice directly to the skin.Keep the jaw stable
If possible, support the jaw gently using a soft cloth tied under the chin and over the head to keep it in place.Avoid eating or drinking
Do not eat solid foods until you are seen by a dental or medical professional. Stick to water if needed.Get emergency care
A suspected broken jaw is a medical emergency. Visit an emergency room or dental emergency center immediately.
Diagnosing a Broken Jaw
To confirm a fracture, a dental or medical provider will:
Perform a physical exam
Ask about the injury or cause of trauma
Use X-rays or CT scans to locate the break and evaluate the damage
Once diagnosed, your provider will discuss treatment options. These may vary based on the location and severity of the fracture.
Treatment Options for a Broken Jaw
Treatment for a broken jaw depends on how serious the injury is:
Mild fractures may heal with rest, pain medication, and a liquid diet. The jaw may be stabilized with a bandage or sling.
Moderate fractures might require the jaw to be wired shut for several weeks so the bones can heal in place.
Severe fractures may need surgery to realign the jaw and install small plates or screws to keep it stable.
During recovery, you may need to follow a soft or liquid diet, avoid physical activity, and attend regular follow-ups with your dentist or surgeon.
Complications of an Untreated Jaw Fracture
Leaving a broken jaw untreated can lead to serious problems such as:
Chronic jaw pain
Infection near the fracture site
Improper bite alignment
Trouble chewing or speaking
Damage to nearby teeth and nerves
Long-term facial changes
That’s why it’s so important to seek professional help if you suspect something is wrong. The earlier the diagnosis, the better the outcome.
