What Are Dental Crowns Made Of?
Dental crowns may be constructed from a number of different materials including, metals, porcelain, resin or ceramic.
Several metals may be used to create a dental crown. Gold, chromium, palladium, or nickel are all popular options. Metal crowns are durable over many years and require less of the original tooth to be removed than other types of crowns may require. Metal is often chosen for out-of-sight molars because of its less natural appearance.
Porcelain-coated metal crowns have the durability of metal crowns with the natural look of ceramic or resin crowns. A metal "edge" of the crown may appear at the gum line. The porcelain coating may also chip through use over time. For these reasons, they are also usually selected for back-of-the-mouth placement.
Crowns made from resin are often a less expensive option for crowns. They do not last as long as other types, so they are less-frequently chosen.
All-Ceramic Or All-Porcelain Crowns
For the most natural appearance, all-ceramic or all-porcelain crowns are the top choice. They are good for anyone looking for a very natural look or who have allergies to metals that are used in other types of crowns. They are typically chosen for visible teeth in the front of the mouth.
Pressed Ceramic Crowns
These dental crowns have the natural look of all-ceramic or all-porcelain crowns but are constructed with a hard inner core. They are the longest lasting ceramic or porcelain type crown with strong durability thanks to the hard inner core.
