Swelling and bleeding can occur within the first 24-48 hours of bone or gum graft surgery. Patients should apply a cold, moist washcloth to the surgery site to control this swelling and bleeding. In 20-minute intervals, this should be used with gentle pressure. It is preferable to avoid hot food and drinks for the first 24 hours after surgery. Patients should also avoid actively rinsing their mouths during this initial day-long duration. Ignoring these guidelines can cause bleeding to persist.
