Q. I have had porcelain veneers on my front four teeth since i was about 12. I am unhappy with the appearance of my smile. I have gaps and a bit of an over bite. I was told by a dentist that before he could give me new veneers i would need braces to bring my teeth closer together, but many of the orthodontists i have seen say i would have to have the veneers removed and have braces on my teeth underneath. Is it possible to wear any sort of brace on top of veneers? Thanks!
