A bad smell and taste is common with a dry socket and the severity varies from person to person. A dry socket can also cause immense pain, as stated by WebMD.
Dry socket is a complication that occurs after a tooth is extracted. It can happen when the blood clot where the tooth once was dislodges or fails to form. This leaves the nerves exposed to the air and food can get caught in it, which can lead to an infection, according to Silverbell Dental. People that smoke, have poor dental hygiene habits or have a history of dry sockets are more likely to suffer from them.
