I had 2 crooked teeth so back in 2014 I got 2 ceramic crowns on them. I also needed ortho treatment so in 2017 I got braces. My doctor told me to get old caps replaced but told that it isn?t possible for me to get zirconium CAPS after the braces are removed because then he will not be able to put retainers on the backside of my teeth after braces are removed! He replaced my old caps with Ceramic + metal caps! Which is looking very fake and unmatched with the other teeth! I am not satisfied since it is on my front teeth .please tell me is it not possible for me to get zirconium Caps along with retainers? Even after braces I feel my smile isn?t looking good.
