Day 8 post first molar extraction, dr.visit monday, all looked good. wound like a canyon. now inside 2 new patches pinkish white patches, new gum?

From Ur description: It sound fine and within normal limits of healing. However, only by seeing you personally can one be certain. Your dentist on monday can tell you for sure.

Probably healing.: It is not uncommon for the extraction sites to take literally months to close and heal. If you saw your dentist today and all is well; then i would not worry. Just keep the area clean and rinse as directed.
