My older son with the bad teeth, same thing happend, although it was his back teeth only, he had to get caps on all of his back teeth, I think he has 6 or so caps. He is now getting his adult teeth and it is unclear wheather they are good or bad, we will wait and see. I totally freaked too, we went and saw a specialists and got the caps, he did have to be be sedated to have the caps put on which was kind of scary. He has had them on since he was 3 years old, now 7, and has not had any other problems.

Good Luck
