For years, people that have had dental crowns put in have had to deal with the unsightly grey line along there gums that develops from porcelain-fused to metal crowns. If the dentist was working with low quality metals, the line would actually turn black, marring your smile permanently. Within the last few years, there have been many advancements in cosmetic dentistry, one of which is Zirconia crowns. They help eliminate the dreaded black line.
Zirconia Crowns have several advantages of both traditional Gold Crowns and Porcelain.
- Strength and longevity: Zirconia is virtually indestructible whereas Porcelain crowns are prone to chipping. Crowns have a lifetime of around 10 years. Zirconia should last a lifetime.
- Less tooth removal: In cases where their is not much room for porcelain build up – for example if an tooth abutment is already quite bulky, a Zirconia Crown can be used because if provides more strength in less volume than a porcelain crown.
