causes of dry sockets
Dry socket is caused by a blood clot not forming properly, dissolving too quickly, or dislodging at the site of a tooth extraction before it has the chance to heal. After a tooth is pulled, a blood clot forms at the site. The clot gives the bone and nerve endings a protective coating.
Smoking can cause dry socket. A smoker will inhale, sucking on a cigarette. This action can dislodge the clot in the socket. Smoking also reduce blood supply to the affected area, reduces healing, introduces toxins to the area, and can injure the gums.
