Patient Education


Jaw Injuries and Disorders

Your jaw is a set of bones that holds your teeth. It includes:

  • The maxilla, which is the upper part of your jaw. It holds your top teeth in place and doesn't move. It also supports the muscles involved in chewing and facial expressions.
  • The mandible, which is the lower part of your jaw. You move it when you talk or chew. It also holds your lower teeth in place.
  • The temporomandibular joints (TMJs), which are two joints (one on each side) that connect your mandible to your skull.

Jaw problems can include:

  • Fractures (broken bones).
  • Dislocations, which are joint injuries that force the ends of your bones out of position.
  • Temporomandibular disorders (TMDs), which are conditions that affect your TMJs.
  • Osteonecrosis, which happens when the blood flow to part of your bone is disrupted. It can cause the bone to break down.
  • Jaw tumors, which can be benign (not cancer) or cancer.
  • Jaw defects, which are birth defects in which your jaw could be missing or deformed.

Diagnostic imaging tests are often used to diagnose jaw injuries and disorders. Your treatment will depend on which jaw problem you have.

Sprains and Strains

A sprain is a stretched or torn ligament. Ligaments are tissues that connect bones at a joint. Falling, twisting, or getting hit can all cause a sprain. Ankle and wrist sprains are common. Symptoms include pain, swelling, bruising, and being unable to move your joint. You might feel a pop or tear when the injury happens.

A strain is a stretched or torn muscle or tendon. Tendons are tissues that connect muscle to bone. Twisting or pulling these tissues can cause a strain. Strains can happen suddenly or develop over time. Back and hamstring muscle strains are common. Many people get strains playing sports. Symptoms include pain, muscle spasms, swelling, and trouble moving the muscle.

At first, treatment of both sprains and strains usually involves resting the injured area, icing it, wearing a bandage or device that compresses the area, and medicines. Later treatment might include exercise and physical therapy.
