I posted here a few weeks ago. I got a tooth extracted number 13 and it's been about a week no pain really but i got some yellow stuff where the hole is. I was wondering if this was new tissue forming or infection. Tooth 12 has a huge hole on the back side of it and it's been hurting im getting it filled tomorrow. Is the yellow stuff inside the tooth normal? I know where the hole is the gum didn't really form a perfect circle. Wondering what to do.
