Dentists may prescribe medications for mouth bleeding, but will usually stop it with simple procedures, such as applying firm pressure with moist gauze or tea bags on the bleeding location for 30 minutes, according to the American Academy of Oral Medicine. Dentists also use socket packing or stitches for bleeding.
Patients recovering from dental procedures that result in bleeding should not rinse, spit, use a straw, drink hot beverages or smoke for the first 24 hours after the procedure, states the American Academy of Oral Medicine. They should not eat sharp or hard foods, such as nuts or pretzels, for two to three days. If bleeding continues for more than several hours or a very large blood clot forms, the patient should contact the dentist or go to the local emergency room, says the American Academy of Oral Medicine.
