Zirconia is an extremely hard natural crystal. The hardness of zirconia makes it unbreakable, which is why it lasts a very long time inside the human body. Zirconia crowns are made from protein and zirconium materials, which gives them a whitened, clean crystal look.
The biggest advantage of choosing zirconia crowns is that you avoid the unattractive lines on the teeth that another type of dental crown can leave. Zirconia crowns are also quite an expensive solution, which is a result of their durability and the attractive appearance they offer.
