Why does the gum around crowns look purple?
This can occur for several reasons: the crown may not fit well, it may be too far under the gum, or it may have a metal base that blocks light. Teeth are like little fiber optic units. When light hits them, it illuminates the teeth and the surrounding gum tissue to give it that healthy pink glow. Metal blocks the light, causing the tissue to look dark. Crowns that are all ceramic are best for a natural appearance.
