Hole in tooth:( Please help:(?

You have nothing to worry about, if they treat it like a cavity, the dentist will numb your mouth and give you a shot in your cheek. It doesnt hurt AT ALL. Then they have a tool thats shaped like a thick needle, they put this tooth filler thing on it and press in into the hole. Sounds painful but trust me, I just got my first cavity and I was freaking out, but it didnt hurt at all.
