General Discussion

While antibiotics wouldn’t help a tooth infection per se, they would be quick and easy to prescribe to prevent an infection from becoming systemic or spreading further around his face and head. Taking a plane with a tooth/jaw infection would be quite painful, and potentially dangerous since he’d be stuck in the air for many hours. His staff and diplomatic staff would likely have insisted on the quick solution of antibiotics to prevent worsening/spreading and to combat fever, and some high-test pain meds, before shipping him home. But the pic may also be showing facial asymmetry that is not due to the side of his face swelling. That could be neurological.
