Are There Different Types of Dental Crowns Available?
Dental crowns, often referred to as "caps," are tooth-shaped restorations that cover and protect a damaged or weak tooth. But with various materials and functionalities, there's not a one-size-fits-all crown. Here's a look at some common types:
Metal Crowns: Known for their exceptional durability and longevity, metal crowns are traditionally crafted from gold alloys or other strong metals. While highly resistant to wear and tear, the metallic color might be a drawback for some patients, especially for crowns placed on front teeth. Metal crowns are a good choice for restoring molars that take on significant chewing pressure.
Porcelain-Fused-to-Metal (PFM) Crowns: PFM crowns offer a balance between aesthetics and strength. A metal substructure provides a strong foundation, while a layer of porcelain is bonded to the metal, creating a more natural tooth-like appearance. However, some patients might experience a dark line at the gum margin due to the metal base. PFM crowns are a versatile option for both front and back teeth.
