Thanks for your query.
First of all i would like to tell you that it is a normal healing process,nothing to get worried.
Clot formation and white area is healing tissue and this clot should be retained in the place.
I would like to suggest you do not disturb the healing tissue and maintain good oral hygiene
One more thin if there will be severe pain
of bleeding,then it will not be good sign,in this case you should take immediate medical help
As you provided the detail,nothing to get worried.
