Dry socket is more likely to occur following a difficult tooth extraction. It is thought that excessive force applied to the tooth, or excessive movement of the tooth burnishes the bony walls of the socket and crushes blood vessels, impairing the repair process.
A dry socket is caused by the partial or total loss of a blood clot in the tooth socket after a tooth extraction. Normally, after a tooth is extracted, a blood clot will form as the first step in healing to cover and protect the underlying jawbone. If the blood clot is lost or does not form, the bone is exposed and healing is delayed. In general, a dry socket is a result of bacterial, chemical, mechanical, and physiologic factors. Below are examples for each: Bacterial: Preexisting infection that is present in the mouth prior to a dental extraction such as periodontal disease (or periodontitis) can prevent proper formation of a blood clot.
