Why surgical removal of lower wisdom tooth is dangerous??

Most wisdom tooth extractions don't result in long-term complications. However, removal of impacted wisdom teeth occasionally requires a surgical approach that involves making an incision in the gum tissue and removing bone. Rarely, complications can include:

Painful dry socket, or exposure of bone when the post-surgical blood clot is lost from the site of the surgical wound (socket)

Infection in the socket from bacteria or trapped food particles

Damage to nearby teeth, nerves, jawbone or sinuses
