Dry socket, a serious painful complication after dental extraction, occurs in the lower jaw in the majority of cases, most often in the lower jaw for blocked wisdom teeth, while for the upper jaw dry socket is very rare, generally common dry socket occurs in the lower jaw for wisdom teeth, as well as the lower jaw for the first molar and the lower jaw for the second molar. Dry socket generally refers to a large trauma to the tooth extraction and the corresponding area does not form a good blood clot, which can cause severe pain and pain medication is not very effective, along with a significant bad breath. In contrast to the significantly rich blood supply in the upper jaw of the lower jaw, the blood clot will generally form very quickly after the extraction of the tooth, and the chances of dry socket are minimal.
