I fear to look to closely at my extraction sites but I have noticed something similar. The extractions began about 2 months ago... I'm just assuming that it is some kind of gauze plug, maybe? And that it will be expelled naturally as the hole heals up. No pain either, so I'm sure it's normal, whatever "it" is. I'd be interested to find out. Following... in the hope someone who knows answers. Failing that, I'll ask at my next visit. Now I'm curious, but not worried.
Now I am more curious, but not worried, there must be an explanation. If it was a bit of tooth, it would be painful. It's soft you say? I haven't dared touch mine... Not a biologist but I would venture to say it is part of the healing. Maybe some tissue regeneration? Mass production of the necessary white blood cells account for the colour? Some of my extraction sites have already, apparently, closed over and there is no white bits to be seen now. Pure guess work, but I'd venture to say, don't worry about it.
The white stuff is very normal healing - it’s called granulation tissue. Best to leave it alone and not look at it too much. Unless you’re having pain that’s not managed with over the counter pain medication, you should be totally fine. If you’re having pain, you should call the dentist who did the extraction.
