There are two major types of dental crowns:
• Porcelain-fused-to-metal crowns or “conventional crowns” are made of an internal metal part covered by a layer of ceramic. Even though there is metal underneath the ceramic, we can still match the color of your adjacent teeth and make them look similar. However, if your gum recedes, which happens very often, the metal underlying the crown will become visible, leaving a dark line at the gum. These crowns are a good option for your back teeth.
• All-ceramic or all-porcelain crowns are commonly used nowadays to provide you with the best aesthetic and natural color. These metal-free crowns are an excellent choice for front teeth but also for back ones, and are also recommended for those who suffer from metal allergies. Few years ago, a new material called “Zirconia” was developed to increase the strength of the full ceramic crowns. Those new crowns are more resistant than the porcelain-fused-to-metal crown and almost unbreakable. They provide also a great solution for clients with grinding problems.
