I have had fill ins, its nothing to be scared of. They give you a shot to the gum you only feel a pinch to the gum no real pain at all. It nums the gum and the teeth and you feel no pain. When they drill down on your teeth you wont feel it, nothing to be scared of man. Just remember to start brushing your teeth daily now and you wont have this problem, oh and lay off the coke its horrible for the teeth!
