There are a few risks associated with tooth extraction. However, if your dentist recommends the treatment, the advantages will certainly outweigh the minor risk of complications. A few days following the tooth extraction, a blood clot forms in the socket — the hole in the bone where the tooth was pulled. However, if the blood clot does not form or dislodges, the bone inside the socket may become exposed, a problem referred to as “dry socket.” If this occurs, the dentist will cover the affected area with a sedative dressing for a few days to protect it. A new clot will form during this period. Other risks include: Bleeding that persists for more than 12 hours. Severe fever and chills, an indication of an infection. The feeling of nausea or vomiting. Coughing Shortness of breath and chest pain. Redness and swelling at the extraction site.
