Mandibular Contusion

A mandibular contusion is a deep bruise of your jaw. Contusions are the result of an injury that caused bleeding under the skin. The contusion may turn blue, purple, or yellow. Minor injuries will give you a painless contusion, but more severe contusions may stay painful and swollen for a few weeks.


A mandibular contusion comes from a direct force to that area, such as falling or a punch to the jaw.


  • Jaw pain.

  • Jaw swelling.

  • Jaw bruising.

  • Jaw tenderness.


The diagnosis can be made by taking your history and doing a physical exam. You may need an X-ray of your jaw to look for a broken bone (fracture).


Often, the best treatment for a mandibular contusion is applying cold compresses to the injured area and eating a soft diet. Over-the-counter medicines may also be recommended for pain control.


  • Put ice on the injured area.

  • Put ice in a plastic bag.

  • Place a towel between your skin and the bag.

  • Leave the ice on for 15-20 minutes, 03-04 times a day.

  • Eat soft foods for 1 week. Soft foods include baby food, gelatin, cooked cereal, ice cream, applesauce, bananas, eggs, pasta, cottage cheese, soups, and yogurt. Cut food into smaller pieces for less chewing. Avoid chewing gum or ice.

  • Only take over-the-counter or prescription medicines for pain, discomfort, or fever as directed by your caregiver.

  • Avoid opening your mouth widely. This includes opening your mouth to eat large pieces of food or to yawn, scream, yell, or sing.

  • You have any cracking or clicking (crepitation) in the jaw joint.
