From photos-: From the photos alone it looks fine. If you have no pain and no swelling, i wouldn't be concerned. You can always call the surgeon to discuss any issues and ask to be seen for post-op evaluation.

Wisdom tooth ok: Just make sure you keep the area clean and the socket irrigated. If experience pain see the surgeon for possible post operative infection control.
