I have had a wisdom tooth extraction 3 days ago. my tooth was horizontally placed in jaw and it took about 5 hrs to remove however a tiny part of root has still remained there. The Dr said it is located in bone and very close to nerve and he said we cannot remove it now so you should wait and see if there would be inflammation there I have to go for another surgery. Right now I have still lots of pain and cannot open my mouth. Please let me know what should I do? I want to also know how dangerous it is to keep a part of root remained in bone? Please help me.
