Uses and Types of Dental Crowns
Dr. Robert Madden practices at Southwest Family Dentistry. Robert Madden, DDS, MBA, has many professional interests as a dentist, including the construction of crowns.
Crowns serve several functions, such as supporting a tooth that has broken or eroded, covering implants, and keeping a bridge in place. They can also prevent damage to a weak tooth and hide a discolored one. Several types of crowns made of various substances can accomplish these and other goals:
– Stainless steel crowns are temporary, remaining in place until a permanent crown is available from a laboratory. They are popular in children’s dentistry because they cover teeth soon to be lost and require only one visit.
– Metal crowns require less removal of natural tooth tissue. They are longlasting and hold up well to biting and chewing.
– Porcelain-fused-to-metal crowns look more natural because they match the color of other teeth. However, the porcelain in them can break off. All-ceramic or all-porcelain crowns provide a better color match than porcelain-metal but are less strong. All three types tend to wear down the opposing teeth.
– All-resin crowns are an inexpensive choice, but they are more likely to break than porcelain-fused-to-metal ones.
