These concerns need timely assessment but are not always emergencies.
Seek emergency help for trouble breathing, choking, uncontrolled bleeding, fainting, severe confusion, or rapidly increasing swelling.
Contact the treating team promptly for increasing pain or swelling, fever, pus or a bad taste from a wound, worsening numbness, new difficulty opening the mouth, loose fixation, or a bite that is becoming less aligned.
A jaw that dislocates again and becomes stuck should receive urgent medical care; do not try to force it back into place.
Follow-up visits allow the clinician to check the bite, wound healing, joint movement, nerve sensation, and any plates, screws, wires, or elastic bands.

Follow the care team’s instructions for brushing, rinsing, and cleaning around wires or plates.
Avoid activities that could cause another blow to the face until the clinician confirms that healing is adequate.
