Alan wanted to replace his existing two front crowns. Two reasons this had to be done. 1)esthetic and 2)functional. The crowns were extremely bulky and had a metal underlying structure that was showing through. The gum tissue was hypoxic and turning blue around the crowns margins,basically strangulating the delicate tissue. Alan's treatment consisted of removing the crowns and replacing them with well fitting properly contoured all porcelain crowns that look real which allowed the gum tissue to bounce back to health.
