do they usually open the gum and put the graft in after it has completely healed, my dentist says it protect the open area. why do my prior tooth extraction areas itch
Extraction and bone graft are usually not done together. The graft can act as a medium where bacteria can grow. The socket needs to heal before the graft. It could possibly be a dry socket.In a dry socket there is alveolar osteitis and there is severe pain since the underlying bone and nerves are exposed. See your dentist and get it checked. A dental examination will confirm the exact cause of your symptoms. I hope it helps.
Best wishes and regards!
