An extraction is performed to remove a tooth, whether because of disease, crowding, or damage. When extractions are required, the area around the tooth will be numbed and your dentist will remove the tooth. A small amount of bleeding is normal, as your mouth will replace the removed tooth root by forming a blood clot in the area. Caring for your mouth after an extraction is very important. Your dentist will outline how you should care for the area of the extraction. It is important to allow your mouth time to heal, so avoid activities like smoking, drinking through a straw, or eating foods that may aggravate the area.
