Our Mill Creek, WA, dentists Dr. Chad Slocum and Dr. Sara Lundgaard have preserved countless damaged teeth thanks to dental crowns, a versatile restoration that looks just like the crown of a natural tooth. If you are dealing with a weak or injured tooth then you too could benefit from getting a dental crown.
How does a dental crown work?
The purpose of a crown is to preserve and strengthen the natural structure of a damaged tooth. Once the custom restoration is placed it’s designed to encapsulate the tooth above the gum line.
In order for a crown to fit over the tooth, our Mill Creek, WA, general dentist will need to take impressions of your mouth to get the right measurements from which to craft your crown. These measurements are sent to an outside dental lab that will create your crown from a durable tooth-colored material such as ceramic or porcelain so that it looks just like a real tooth. A crown won’t stand out or look different from the rest of your natural smile.
When are dental crowns used?
A crown serves a rather important role in restoring a smile. They are placed over weak, broken or otherwise damaged teeth to support them and to preserve as much of the natural structure of the tooth that’s left after the damage. Not only does it improve the overall shape and look of the tooth but it also protects it from further damage. Teeth that are severely decayed, as well as cracked, fractured, misshapen or root canal-treated teeth may require a dental crown.
While the main purpose of a crown is to restore a damaged tooth it can improve a severely stained or oddly shaped tooth that also affects your smile’s appearance.

A “crown” or a “cap” is the term used to restore a decayed or broken tooth that needs to be completely encased to protect the tooth beneath it. A crown's dual purpose is to restore the tooth's form and function. Decades ago gold was the material of choice for a crown. What we ultimately choose depends on a particular crown's requirements with regard to the tooth's appearance and function, and to some extent what you want.
Gold: Gold crowns last the longest and wear the best (at about the same rate as natural teeth), but they are not used as frequently today, especially if they are visible in a person's smile. Gold crowns are made of cast gold, a technique that has been in use for over a hundred years. They can last for decades, and have been known to last 50 years or more. They tend to cost less per tooth than porcelain or other materials.
All-Porcelain: “All porcelain” crowns have a natural appearance and as technology improves they are gaining popularity. Dental porcelains are composed of ceramic substances that are variations of glass. This gives them their translucent, lifelike appearance — but it makes them brittle and subject to fracture. Therefore all-porcelain crowns may not be a good choice for back teeth because they frequently fail under the biting forces applied during chewing and especially adverse habits like tooth clenching or grinding. Porcelain crowns are made of material that doesn't wear. Consequently, it can cause excessive wear to the teeth they bite against.
Porcelain-Fused-to-Metal (PFM): PFM crowns have been in use for more than 40 years. They combine a substructure of gold or platinum for strength and have porcelain “facings” for the visible surfaces. In some ways they combine the best of both worlds, but they do have some problems; the metal can show through the porcelain, detracting from its life-like appearance. These crowns can have a functional lifespan of about 20 years or more.
New and Future Materials: Newer “pressed-ceramic” restorations and computer-milled ceramics have received good reviews for aesthetics and service. These new materials are being intensively researched. Initial results look good, but we'll have to see how they last over time.
