Thanks for responding. Did your son have any issues with his crowns cracking or anything? My research has shown that that is why many pediatric dentists do not use them in favor of silver. I am like if we have to replace them every two years so be it (unless we have to do anesthesia then that is a problem clearly). I have found a few dentists in my area (3) that use these new tooth colored caps but they either don't take my insurance or think the caps don't fit someone his age well.
