The U-shaped lower jaw often suffers multiple breaks. An upper jaw fracture may cause visible distortion of the face. If teeth fit together properly when the mouth is closed:
Apply ice to control swelling and take ibuprofen or a similar remedy to control pain.
Restrict diet to soft foods and if no improvement occurs within 24 hours, seek dental care. If teeth do not fit together properly when the mouth is closed:
Immediately seek emergency care.
Gently align the jaws.
Immobilize the jaw; wrap a cloth bandage under the chin and secure it over the head.
Apply ice to control swelling.
