Also infection can spread down the tissue spaces to the mediastinum which has significant consequences on the vital organs such as the heart. Another complication, usually from upper teeth, is a risk of sepsis traveling through pathways to which it can possibly lead to endocarditis, brain abscess (extremely rare), or meningitis (also rare).
