Thats why they call it a "practice"

My wife has a whole mouth of old silver, her dentist suggested only replacing them with the white when needed, nothing more. They were only $80.00 each without insurance. I had a chip fixed, 4 months later it fell out, it was in a bad spot, lower front tooth and he said so but replaced it without charge and its been good for 4 years now.

You might try getting someone else to take a look at them, with all the pictures they take now they should be able to nail it down and not guess, I would guess?
