Dislocated Jaw: Causes, Symptoms, Professional Reduction, and Prevention

By Hart 7 min read

Reducing a dislocated jaw is a precise medical procedure that must only be performed by a trained healthcare professional to prevent further injury and ensure proper healing.

How Do You Reduce a Dislocated Jaw?

Reducing a dislocated jaw is a precise medical procedure that should only be performed by a trained healthcare professional, such as an emergency physician, oral surgeon, or dentist. Attempting to self-reduce a dislocated jaw can lead to further injury, nerve damage, or improper healing.

Understanding Jaw Dislocation

A dislocated jaw occurs when the condyle (the rounded end of the lower jaw bone, or mandible) moves out of its normal position within the temporomandibular joint (TMJ) socket, located just in front of the ear. This can happen on one or both sides of the jaw.

  • Anatomy: The TMJ is a complex hinge and gliding joint, facilitating movements like opening and closing the mouth, chewing, and speaking. It comprises the mandibular condyle, the temporal bone's articular fossa, and an articular disc between them. Ligaments and muscles stabilize this joint.
  • Causes: Jaw dislocation often results from:
    • Trauma (e.g., a blow to the jaw, car accident)
    • Sudden, wide opening of the mouth (e.g., a very wide yawn, laughing, vomiting, dental procedures, intubation)
    • Connective tissue disorders (e.g., Ehlers-Danlos syndrome) that lead to joint laxity.
    • Prior history of dislocation, which can weaken the supporting ligaments.
  • Symptoms: When your jaw is dislocated, you will typically experience:
    • Intense pain in the jaw and around the ear.
    • Inability to close your mouth, with your mouth often stuck open.
    • Difficulty speaking or swallowing.
    • Visible misalignment of the jaw, often protruding forward.
    • Drooling due to inability to close the mouth.

Why Professional Medical Intervention is Crucial

While the immediate discomfort might tempt individuals to try and "pop" their jaw back into place, this is highly discouraged and dangerous.

  • Risk of Further Injury: Without proper anatomical knowledge and technique, attempting self-reduction can damage the TMJ's delicate structures, including cartilage, ligaments, and the articular disc.
  • Nerve Damage: The facial nerve (cranial nerve VII) and other important nerves run near the TMJ. Improper manipulation can cause temporary or permanent nerve damage, leading to facial weakness or paralysis.
  • Vascular Injury: While less common, there is a risk of damaging blood vessels in the area.
  • Improper Reduction: An incorrectly reduced jaw may not heal properly, leading to chronic pain, recurrent dislocations, or persistent functional issues.
  • Ruling Out Fractures: A dislocated jaw can sometimes occur alongside a jaw fracture. A healthcare professional will perform X-rays or other imaging to rule out fractures before attempting reduction. Reducing a fractured jaw without proper diagnosis can worsen the fracture.
  • Pain Management and Sedation: Professional reduction often involves pain medication and muscle relaxants, or even conscious sedation, to make the process less painful and allow the muscles to relax, facilitating easier and safer reduction.

The Professional Reduction Process (General Overview)

When you arrive at a medical facility with a dislocated jaw, the healthcare team will follow a structured approach:

  • Diagnosis and Preparation:
    • A physical examination will confirm the dislocation.
    • X-rays are typically taken to rule out any fractures of the jawbone or surrounding structures.
    • Pain relief and muscle relaxants (often administered intravenously) are given to alleviate discomfort and help the jaw muscles relax, which is crucial for successful reduction.
  • Manual Reduction Techniques: Once the patient is comfortable and relaxed, the healthcare professional will perform a manual reduction. While specific techniques can vary, the general principle involves applying controlled pressure to guide the mandibular condyle back into its socket. One common approach, often referred to as the Hippocratic maneuver or variations of it, involves:
    • The clinician positions themselves in front of the patient, often with the patient seated.
    • The clinician places their thumbs (protected by gauze or tape to prevent biting) onto the patient's lower molars or along the alveolar ridge (the bone that holds the teeth).
    • The other fingers wrap around the outside of the jaw.
    • Gentle, sustained downward pressure is applied to the molars, which helps disengage the condyle from the temporal bone.
    • Simultaneously, backward and slightly upward pressure is applied to the front of the jaw to guide the condyle back into the articular fossa.
    • A distinct "clunk" or "pop" may be felt and heard as the jaw returns to its normal position.
  • Post-Reduction Care:
    • Immobilization: The jaw may be gently wrapped with a bandage or a soft cervical collar to limit movement for a few days, allowing ligaments and muscles to heal.
    • Soft Diet: Patients are advised to consume soft foods for several days to weeks to avoid stressing the joint.
    • Activity Restriction: Avoiding wide yawning, chewing gum, or any activities that require wide mouth opening is crucial.
    • Pain Management: Over-the-counter pain relievers or prescription medication may be recommended.
    • Follow-Up: A follow-up appointment with a dentist, oral surgeon, or TMJ specialist may be scheduled, especially for recurrent dislocations.

What to Do While Awaiting Medical Help

If you or someone you know experiences a jaw dislocation, take these immediate steps:

  • Seek Immediate Medical Attention: This is the most critical step. Go to the nearest emergency room or urgent care facility.
  • Avoid Manipulating the Jaw: Do not attempt to force the jaw back into place. This can cause more harm.
  • Support the Jaw: Gently support the jaw with your hands or a soft bandage to minimize movement and discomfort.
  • Pain and Swelling Management: Apply a cold compress or ice pack to the jaw area to help reduce pain and swelling.
  • Stay Calm: Try to remain as calm as possible while waiting for professional help.

Preventing Future Dislocations

For individuals prone to jaw dislocations, proactive measures are important:

  • Avoid Excessive Mouth Opening: Be mindful of wide yawns, limit very hard or chewy foods, and avoid activities that require prolonged wide mouth opening.
  • Manage Bruxism (Teeth Grinding): If you grind or clench your teeth, a night guard can help protect your TMJ and prevent excessive stress.
  • TMJ Exercises: Under the guidance of a physical therapist or TMJ specialist, specific exercises can strengthen the muscles around the jaw and improve joint stability.
  • Mouth Guards: For those involved in contact sports, a custom-fitted mouth guard can offer protection against trauma.
  • Consult a Specialist: If dislocations are recurrent, consult an oral and maxillofacial surgeon or a TMJ specialist. They may discuss options ranging from medication and physical therapy to more invasive procedures like surgical stabilization.

When to See a Doctor (Beyond Acute Dislocation)

Even after a successful reduction, it's important to monitor your jaw and seek medical advice if you experience:

  • Recurrent Dislocations: If your jaw frequently dislocates, a specialist can evaluate the underlying cause and recommend long-term solutions.
  • Persistent Pain or Limited Movement: If pain, stiffness, or difficulty with jaw movement continues weeks after reduction, it could indicate ongoing TMJ issues.
  • Clicking, Popping, or Locking: These symptoms may suggest problems with the articular disc or joint mechanics that require further investigation.
  • Changes in Bite: Any changes in how your teeth fit together after a dislocation should be evaluated.

Understanding the complexity of jaw dislocation and the critical role of professional medical intervention is key to ensuring proper healing and preventing long-term complications.

Key Takeaways

  • A dislocated jaw must only be reduced by a trained healthcare professional due to risks of further injury, nerve damage, or improper healing.
  • Symptoms of jaw dislocation include intense pain, inability to close the mouth, difficulty speaking, and visible misalignment.
  • Professional reduction involves diagnosis (including X-rays), pain management, and manual techniques to guide the jaw back into its socket.
  • Post-reduction care typically includes jaw immobilization, a soft diet, activity restriction, and follow-up appointments.
  • Preventing future dislocations involves avoiding excessive mouth opening, managing bruxism, and consulting specialists for recurrent issues.
