I have felt the same way before, so you are not horrible! ha My daughter was going to have some teeth removed when they found a cavity, and that's the first thing I asked - is it one of the teeth they are going to take out anyway? Sometimes the molars hang around for awhile and don't fall out for a few more years - the cavity could spread to the adult tooth, or if you have it pulled, they will want to put a spacer in. I would look at it this way: at least you have gone all this time with no expense! Your son never had a cavity - that's great.
