Dr. Heck was my dentist when I was a teenager and put a porcelain-fused-to-metal crown on one of my front teeth. I've moved a few times in the 13 years (or so) since then, and seen many different dentists and hygienists as a result. All of them say the same thing: "That's a really nice looking crown." I just left the dentist where I heard the same comment again. The hygienist said she didn't even realize it was a crown until she looked more closely. The only thing that gives it away is the slight dark line at the gum line from the metal. If I ever need it replaced, I'm thinking I may go back to Dr. Heck!
