Frequently Asked Questions


What Are Crowns?

A dental crown is a tooth-shaped "cap" that is placed over a tooth covering the tooth to restore its shape and size, strength, and/or to improve its appearance. When cemented into place, the crown fully encase the entire visible portion of a tooth that lies at and above the gum line.


Why Is a Dental Crown Needed?

A dental crown may be needed in the following situations:

  1. To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth

  2. To restore an already broken tooth or a tooth that has been severely worn down

• To cover and support a tooth with a large filling when there isn't a lot of tooth left

• To hold a dental bridge in place

• To cover misshaped or severely discolored teeth

• To cover a dental implant


What Types of Crown Materials Are Available?

Permanent crowns can be made from all metal, porcelain-fused-to-metal, all resin, or all ceramic.

• Metals used in crowns include gold alloy, other alloys (for example, palladium) or a base-metal alloy (for example, nickel or chromium). Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, they rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.

• Porcelain-fused-to-metal dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. The crown's porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown's porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede. These crowns can be a good choice for front or back teeth.

• All-resin dental crowns are less expensive than other crown types. However, they wear down over time and are more prone to fractures than porcelain-fused-to-metal crowns.

• All-ceramic or all-porcelain dental crowns provide the best natural color match than any other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns and they wear down opposing teeth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.


Temporary Versus Permanent

Temporary crowns are made of acrylic or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by the dental laboratory.


What Are "Onlays" and "3/4 Crowns"?

These are variations on the technique of dental crowns. The difference between these crowns and the crowns discussed previously is their coverage of the underlying tooth. The "traditional" crown covers the entire tooth; onlays and 3/4 crowns cover the underlying tooth to a lesser extent.
