It could be dry socket, I would get the doctor to take a look at it.
thanks hun, yes i have thought it may be that but the "hole" is fine i have to pain there just on the gum at the top and the tooth next to the hole.
You cant always see dry socket. You would have a blood clot in the area that can dislodge, but not necessarily visible to you, which is when the "socket" becomes dry.
also, sometimes my patients complain about dry socket for a couple weeks after the actual event occurs. Even when the extraction site looks healed visibly. I would still get the doctor to look at it, at least to make sure there are no root spurs left in the area, just in case its not dry socket.
