Thanks for your info. I'll ask my dentist again when I go to the follow up visit.
If there is significant bone resorption due to periodontal disease and primary closure of extraction site is not achievable, bone graft to preserve alveolar ridge may not be appropriate. Mutual rapport between you and your treating dentist is extremely important. If you do'nt understand your dentist 's explanation, keep on inquing until you are fully aware of everythong. Please keep in mind many treatment problems arise from poor communications between patient and health care providers.
