As a natural way of cleansing the tooth socket, the body will send more blood to the wound site, triggering bleeding after the performed surgery. Depending on how difficult was, the amount of blood secreted may vary. However, blood clot should be promoted within 24 hours after the surgery. Your dentist will ask you to bite a cotton pad on gently within first few hours to promote blood clot. On the first day, swelling and pain might still be excruciating, causing extreme discomfort while eating, even talking and opening the mouth.
