I have porcelain veneers on my front 8 teeth. Previously, I had bonding on the two front teeth. I like my veneers but loved how the bonding made my front teeth longer; the veneers are shorter. Now the two front veneers are cracked. Can I keep my other veneers and have the two front veneers replaced with bonding? I know it could be hard to get a color match and they might not last as long but lots of beautiful people have two front teeth that are slightly different from the other teeth. Thanks!
