From your quary, i could understand that you have a locked tooth which dentist
is trying to pull by attaching a hook after exposing it from the gum.
the pain in the area around the tooth is normal as there bone remodelling is going on.
but the area of the pain according to you is center of the palate
, i suggest you to visit your dentist as i dont know the position of the tooth which he is pulling.
if you post me the OPG, i could guide you better.
