Personally, I have never had any tooth problems which would require my getting an appointment with a dentist to operate on my tooth or teeth. So, I can't really say how long it's going to take my jaw to numb before it can be operated on.
I have more than five friends who are so unfortunate to be suffering from one tooth problem or another. Some of them have removed at least a minimum of 4 teeth and are still having the same tooth problem especially having a hole in their tooth.
There was this particular girlfriend of mine who had such a bad luck when her dentist was trying to remove one of her tooth and the tooth broke in half with half of it still stuck in her teeth gum. She had to go for a second operation on the same tooth which she almost passed out when the dentist was trying to get the half tooth out of her gum. I really felt so sorry for her.
