A 19 year old man presents 4 hours after leaving his dentist office from wisdom tooth extraction. He has been having bleeding from the socket that will not stop for the last 2 hours. His dentist office is now closed and no one is answering the phone. He has no prior history of excessive bleeding and is not taking any medications. He is hemodynamically stable, and on exam you see a clot in the socket surrounded by a steady ooze of blood, which the patient spits out onto a napkin every minute or so.

Which of the following is recommended as part of management?
