Metal crowns: Gold alloy, other alloys (for example, palladium), or a base-metal alloy are among the metals used in crowns (for example, nickel or chromium). Metal crowns require less tooth structure to be removed than other crown types. Metal crowns are the most resistant to biting and chewing pressures and are likely to survive the longest in terms of wear. Metal crowns are also unlikely to chip or break. The primary flaw is the shiny color. Metal crowns are a fantastic option for molars that are hidden from view.
Porcelain, fused to metal crowns: Dental crowns made of porcelain-fused-to-metal can be color-matched to your natural teeth (unlike the metallic crowns). However, when compared to metal or resin crowns, this crown type causes more wear to the opposing teeth. The porcelain element of the crown can potentially chip or crack. Porcelain-fused-to-metal crowns, as compared to all-ceramic crowns, look the most natural. However, the metal beneath the crown’s porcelain can occasionally show through as a black line, particularly around the gum line and much more so if your gums recede. These crowns are suitable for both front and back teeth.
All-ceramic or all-porcelain dental crowns: All-ceramic or all-porcelain dental crowns have the best natural color match of any crown type and may be better for persons who are allergic to metals. They are, however, not as sturdy as porcelain-fused-to-metal crowns, and they wear opposing teeth down a little more than metal or resin crowns. For front teeth, all-ceramic crowns are a viable option.
All-resin crowns: Dental crowns made entirely of resin are less expensive than other crown kinds. However, unlike porcelain-fused-to-metal crowns, they deteriorate with time and are more prone to fractures.
