Although not news in any sense of the word, many people keep enquiring about the metal free option when it comes to getting dental crowns made. People just like the idea of getting crowns that do not have a surgical steel inner structure. This is interesting, as the structure is hypoallergenic and completely covered by tooth colored porcelain, so most people will never even be able to tell what kind of crown you have on at all. But still people are interested in a metal free option, which just shows us that people have some kind of weird, built in aversion to metal and metallic products, as far as medical things are considered.
