Types of Dental Crowns

There are different types of dental crowns available. While some are made of stainless steel, many others are made of metals. You will also find metal, all resin and ceramic dental crowns.

Stainless Steel Crown

They are pre-fabricated crowns used for temporary treatments. These crowns are placed over permanent teeth to protect the tooth. Stainless steel crowns are more commonly used for restoring a child’s tooth. They are placed over a primary tooth which is susceptible to decay. Since these crowns are placed over a primary tooth which eventually makes room for the permanent tooth, the crown naturally comes off in due time. Stainless steel crowns are cost-effective solutions for children who need multiple dental visits to restore their teeth.

Metal Crown

Gold alloy, base metal alloy such as nickel and chromium are another type of dental crowns. Metals crowns are preferred because they last longer and can withstand biting and chewing. In comparison to other types of crowns, metal crowns can be placed with minimum wear and tear and with less removal of tooth structure. Since metal crowns are hard, they rarely chip or break. However, it is best to use metals for out-of-the-sight molars because the metallic color looks very odd on front teeth.

Porcelain on Metal Crown

One of the main reasons why porcelain-on-metal crowns a preferred choice is because they can color match with the adjacent teeth. However, the disadvantage of this type is that the porcelain portion can easily chip or break off even though they look just like normal teeth. Porcelain fused on metal crowns are often use for front or back teeth.

All-Resin Crown

All-resin crowns are the least expensive crowns available in the market. But over time they can easily wear down and are more prone to cracks.

All-Ceramic or All-Porcelain Crowns

The all-ceramic or all-porcelain crowns are most commonly used for front teeth as they exactly match the natural color of the teeth. These crowns are most suitable for people who are allergic to metals and cannot wear the porcelain-fused-to-metal crowns.But the all-ceramic or all-porcelain crowns tend to wear down more readily.

Additionally there are two categories of dental crowns – temporary and permanent crowns. While temporary crowns are made in dentist’s office, the permanent ones are made in dental laboratories.
