How can a dentist determine if there is decay under a crown?

The crown blocks the x-ray, right? So how can a dentist tell if there is decay right under the crown?

1. The dentist can tell even with the crown on, he could also remove the crown to see for sure.
2. By through clinical examination the dentist can make out if there is decay under the crown. You must remember that dentist undergo rigorous training and education which enable them to do this.

3. HOW CAN THE DENTIST KNOW? by using an instrument known as an EXPLORER to find a sort spot, which is decay even if a crown blocks the x-ray from showing it.
4. I agree.
