How to Heal a Broken Jaw: Treatments and Recovery

A broken jaw is a serious injury to the lower jawbone. This bone is essential for speaking, chewing, and maintaining facial structure. A fracture can significantly impair daily activities and requires prompt medical attention to prevent complications.

Recognizing a Broken Jaw and Immediate First Steps

Recognizing signs of a broken jaw helps in seeking timely medical help. Pain in the jaw area, worsening with movement, is common. Swelling, bruising, or bleeding from the mouth may occur. Difficulty opening or closing the mouth, jaw stiffness, or teeth misalignment are also indicators. Some may experience numbness in the lower lip or chin.

Before medical help arrives, stabilize the injury and manage discomfort. Gently support the jaw to prevent movement, using hands or a bandage wrapped under the jaw and over the head. Apply a cold compress or ice pack wrapped in a cloth to the affected area for 15 to 20 minutes to reduce swelling and pain. Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can be taken following recommended dosages to manage initial pain. Seek emergency medical attention, as breathing problems or heavy bleeding can occur.

Medical Treatment for Jaw Fractures

At a medical facility, diagnosis begins with an examination. Imaging techniques are then employed to confirm the fracture and assess its severity. X-rays are frequently used, while computed tomography (CT) scans provide more detailed images, helping determine the precise location and nature of the fracture.

Treatment varies based on fracture severity and type. Non-surgical methods suit less severe fractures without significant displacement. Maxillomandibular fixation (MMF), commonly known as jaw wiring, is a technique where the upper and lower jaws are bound together. This involves attaching arch bars to teeth and connecting them with wires or elastic bands to immobilize the jaw. This stabilization allows the bones to heal in proper alignment, often for a period of 4 to 8 weeks. Elastic bands and splints can also hold the jaw in place.

For moderate to severe fractures with significant displacement, surgery is often necessary. Open reduction internal fixation (ORIF) realigns fractured bone fragments, stabilizing them with small metal plates and screws. These secure the bone, promoting healing and often reducing the need for prolonged jaw immobilization compared to some closed techniques. The choice between approaches depends on fracture characteristics, location, and patient dental status.

Navigating the Healing and Recovery Journey

The healing and recovery journey after a jaw fracture requires diligent adherence to medical guidance. A modified diet is essential, starting with liquids and progressing to soft foods. For the first one to two weeks, a liquid or pureed diet is necessary, requiring foods to be blended with liquids like water, broth, or milk to achieve a thin consistency suitable for sipping. Gradually, a non-chew diet of easily mashed foods like scrambled eggs or mashed potatoes can be introduced. Progression to a soft diet occurs around weeks four to six, with a return to a more normal diet after six to eight weeks.

Pain management is another important aspect. Prescribed medications alleviate discomfort and should be taken as directed. Cold compresses can reduce swelling, especially after injury or surgery. Non-steroidal anti-inflammatory drugs (NSAIDs) may also manage pain and inflammation.

Oral hygiene is important, especially with an immobilized jaw. Brush teeth after every meal and before bedtime, using a small, soft-bristled toothbrush around wires or arch bars. Rinse the mouth with warm salt water or a prescribed mouth rinse several times daily to remove debris and prevent infection. A water pick can dislodge food particles.

Activity restrictions protect the healing jaw. Avoid strenuous activities, heavy lifting, and contact sports for several months to minimize re-injury. While initial bone healing takes 2 to 6 weeks, full recovery for moderate to severe fractures may extend to 3 to 6 months. Temporary side effects like jaw stiffness, numbness, or muscle weakness are common and typically resolve. Jaw-opening exercises may be recommended to restore normal function and mobility.
