I had a bone grafting procedure 4 months ago. It was meant to reinforce the bone surrounding the tooth that was still attached. The surgeon put more bone material than was needed to fill the gap because he didn't want to throw away the remainder. He told me that he had compacted it up there as much as he could. 4 days later some of it came out from underneath the gum. But 4 months later and my gum is still inflamed, white grains are sometimes coming out one at a time. The gum looks like a starry night sky with granules scattered around a bigger area than operated on. What is going on? Are those white sharp granules going to make their way out, or dissolve or stay in there and irritate my gum forever? Any advice would be greatly appreciated. My regular dentist doesn't have a clue.
