I had an extraction on #7 with a bone graft done 1 week ago today. Yesterday I saw my dentist he confirmed everything looked fine. I just now noticed that above my temp crown which have a temp brisge for #7, there is a small gap. Its on the front part of my gums, there are sutures and then gums, then a small gap or hole if you will. When I swish with wash or salt water I can feel it come through. I dont know if it was there yesterday but, is this normal?
