I finally got my severely infected tooth extracted three weeks ago. After following all of the doctor's instructions, I still developed a dry socket. The dentist cleaned it out and packed it with medicated gauze and after a few days of doing this, it has completely healed. Today, I noticed a bubble forming in the extraction hole. I can also feel something sharp poking out of this bubble. I can no longer feel any pain from the extraction site.
Should I be concerned? Please advise! Thanks.
