Your primary concern when dealing with a mouth/jaw injury is ________________.

The primary concern when dealing with a mouth or jaw injury is ensuring a clear airway. This is crucial because injuries to the mouth and jaw can lead to swelling, displacement of teeth, or even bone fragments, which may obstruct the airway. Maintaining a clear airway is essential for the victim's survival, as any blockage can lead to respiratory distress or failure.

Although controlling bleeding and addressing loose teeth are important aspects of managing a mouth or jaw injury, they become secondary to ensuring that the victim can breathe properly. Permanent scarring may be a concern for aesthetic purposes but is not an immediate life-threatening issue in the context of an acute injury. Thus, the priority lies in assessing and maintaining airway patency to prevent serious complications.
