I had full-mouth restoration done with no-prep veneers a few months ago. I did 0.5M1 shade because on the sample tooth on the shade guide it didn't look that white, also the doctor said over time they may get more translucent and my natural color underneath will start to show. I feel like they are too white and thinking about re-doing the in 1M1 shade. Will that make a difference? Also, I feel like the 0.5M1 on my bottom teeth are darker and look better, so change top front only?
