Q. I had a complete restoration, Empress Crowns, with several veneers on the front lower teeth. The color I picked was the 2nd to the whitest on the color panel. I always wanted to have really white teeth and my smile was narrow…that is why I got the work done. Now, 7 years later, my teeth look almost 2 shades darker. I was told that the porcelain would not change color. What is happening and what can I do about it? My new dentist indicated that as I age, my real teeth are getting darker. My original dentist never mentioned any such thing. I thought I would always have a bright white smile.,
