Sana is an 18-year-old female who presents to the emergency room with prolonged bleeding following extraction of a wisdom tooth. The extraction was performed earlier that day and she was sent home with packing to be removed 1 hour later. She bled through the packing by the time she got home and has continued to bleed for the past 2 hours. This is her first tooth extraction and she has no previous history of surgical procedures. On questioning, she describes her periods as “heavy”, but her mother and grandmother reported a similar experience so she assumed that was normal. Physical examination reveals constant oozing from the site of extraction, severe edema of her cheek and a large ecchymosis along her jaw line.
