Call 911 or go to the ER for these signs
Some dental problems are medical emergencies. Get emergency care right away if you have:
- Difficulty breathing or swallowing
- Swelling of the face, jaw, floor of the mouth, or neck — especially if it is spreading
- Swelling that affects your eye or makes it hard to open your mouth
- A high fever combined with mouth or facial swelling
- Bleeding that won't stop after 10–15 minutes of firm pressure
- A knocked-out adult tooth, or an injury to the jaw, head, or face
When in doubt, consider it an emergency and seek care now.
When Jaw Pain Is an Emergency
If you’ve had a blow to your face or jaw during an accident, fall, or injury and you now have severe pain, swelling, or trouble moving your jaw, you need emergency care right away. A fractured or dislocated jaw is not something to manage at home or wait out—it requires immediate evaluation by an ER doctor or oral surgeon.
Signs of a Fractured or Dislocated Jaw
After a traumatic injury to your face or jaw, watch for these warning signs:
Severe pain — especially pain that gets worse when you try to move your jaw or touch the area.
Swelling and bruising — noticeable puffiness on one or both sides of your face, particularly around the jaw.
Difficulty opening or closing your mouth — you may feel your jaw is “stuck” or won’t move smoothly, or you cannot open it fully without pain.
Your bite feels different — your upper and lower teeth no longer line up the way they did, or you feel a sudden shift.
Visible asymmetry — one side of your face or jaw looks noticeably different from the other, swollen, or misaligned.
Numbness in your lower lip or chin — this can signal nerve injury and requires urgent assessment.
Difficulty chewing or swallowing — pain or inability to eat even soft foods.
If you have any of these signs after a facial injury, go to an emergency room or call 911 immediately. Do not try to “pop” your jaw back into place yourself.
Is This Different From Regular Jaw Pain?
Jaw pain can also come from other causes—like temporomandibular joint (TMJ) problems, teeth grinding, or muscle tension—which develop slowly over time and don’t follow an injury. Those issues usually involve clicking, popping, or aching rather than sudden severe pain and swelling after trauma. If you have non-injury jaw pain, clicking, or limited opening that started gradually, see your dentist for evaluation; that is not an emergency. However, if your jaw pain began immediately after an accident or blow, treat it as a potential fracture and seek emergency care.
What Happens at the ER
When you arrive at an emergency room with signs of a jaw injury, medical staff will:
- Ask about your injury and when it happened
- Do a physical exam to check your alignment, movement, and sensation
- Order X-rays or a CT scan to confirm whether there is a fracture or dislocation
- Contact an oral and maxillofacial surgeon if needed
A regular dentist’s office cannot safely treat a fractured or dislocated jaw—the ER or an oral surgeon has the imaging equipment and expertise to do so.
During and After Emergency Care
Treatment depends on the fracture’s location and severity. You may need rest, dietary changes (soft foods), and careful attention while your jaw heals. In some cases, surgery is required. Your ER doctor or oral surgeon will explain your specific plan and any follow-up appointments with a dentist or surgeon.
Do not ignore signs of a fractured jaw hoping it will heal on its own. Untreated fractures can lead to misalignment, difficulty eating, speech changes, and nerve damage.
How MediMouth Helps
If you’ve been treated for a jaw fracture or dislocation at an ER or with an oral surgeon and need ongoing dental care during recovery or after healing, MediMouth can help you find a dentist in Arizona who can support your follow-up care and monitor your healing. In the immediate aftermath of a fracture, however, your priority is emergency evaluation—not routine dental care.
Frequently asked questions
What's the difference between a dislocated jaw and a fractured jaw?
A dislocated jaw means the jawbone has slipped out of its socket; a fractured jaw means the bone is cracked or broken. Both require emergency evaluation. A dentist can help, but an oral surgeon or ER doctor is needed to safely restore the jaw to its proper position.
Can I wait and see a dentist in a few days if my jaw hurts after an injury?
No. If you have signs of a fractured or dislocated jaw—severe pain, swelling, difficulty opening or closing your mouth, or a change in your bite—go to an emergency room or call 911 right away. Delaying care can lead to serious complications, including permanent nerve or joint damage.
How is a fractured jaw treated?
An ER doctor or oral surgeon will take X-rays or a CT scan to confirm the fracture and plan treatment. Depending on the break's location and severity, treatment may include rest, pain relief, and special care to allow healing—or surgery if needed. You'll follow up with an oral surgeon or your dentist during recovery.
