I had my upper left wisdom tooth removed tuesday afternoon, didnt bleed for very long at all and havent had any pain. I checked the site about 15mins ago and it looks strange like i can see the hole but it looks like there's another bit beside it thats all grey. Im so scared of getting dry socket. I had very bad pain all the time before the extraction which is why they removed it. Please help. It could just be the angle that it is and they grey could be in the hole.. just need reassurance. And if it is in the hole is this normal healing or signs of dry socket?
