Porcelain Crown more abrasive than Gold?
I have read that porcelain is much more abrasive to other nearby teeth than gold is? Currently I only have one gold crown and a porcelain crown side-by-side and I hate the latter. The gum is often sensitive and I finally got a water pik MAINLY because of that tooth (flossing wasn’t helping much). Its my ‘special needs’ tooth. It has been done FOUR times since 1992/3. I have seen some gold crowns that appear to be GOLD on the biting surface and white on the ‘smile’ surface. Is that a common procedure?
