A crown is sometimes termed a "cap" or "jacket." A crown will restore a large filling or a cracked tooth to its original size, shape and tooth color. A crown may be recommended after root canal therapy has been completed, as the tooth tends to become brittle and is more likely to fracture. A crown can strengthen and protect the remaining tooth structure and improves the appearance of your teeth. With the advances in technology, we now have the ability to make ceramic crowns with no metal.
To place a crown, your dentist must reduce 1-2 mm of the tooth to make room for it. Your dentist will then use a piece of thread or cord or use a laser to push the gum down around the tooth, to take an impression of the tooth. The impressions are sent to the lab where the crown is made. During that time, you will have a temporary crown. These crowns are usually made of plastic and are made in your dentist's office on the day of your visit. They are not meant to last. If a temporary crown is left in the mouth, the cement eventually washes out and the tooth can decay. At a second visit, your dentist will remove the temporary crown and test the permanent one. Sometimes crowns need additional polishing, glaze or some other adjustment before they are placed. Once the crown is ready, it's cemented to your tooth.
No more conventional impressions, temporaries and long waiting periods!
We have a computerized restoration system that can fabricate restorations such as crowns, inlays, onlays, veneers and more in our office.
CEREC restorations are milled out of a solid ceramic block in just a few minutes. They are then ready to be placed immediately. Everything can be finished in a single appointment!
Crown lengthening is a surgical procedure that re-contours the gum tissue and often the underlying bone of a tooth. Crown lengthening is often for a tooth to be fitted with a crown. It provides necessary space between the supporting bone and crown, which prevents the new crown from damaging bone and gum tissue.
If your smile is in need of a makeover, crowns can provide predictable results. Crowns can give an unattractive tooth back its beautiful shape and color. For smaller or worn down teeth, a crown can restore the natural size of the old tooth. A crown can replace either part of or the tooth's entire structure. For procedures requiring only the areas visible from the outside, a veneer may be an alternative option.
A post and crown is used when there is not enough tooth structure left for retention after your root canal procedure to support a crown, a post will be placed upon the tooth root. Dr. Smith will then make a crown buildup around the post. After that, a crown will be placed on the buildup.

There are three basic types of crowns:
1) Porcelain outer surface with a metal base crown.
2) Pure porcelain or composite crown.
3) All metal crown, which is usually gold.
They all differ in durability, strength, appearance and cost.
These are very aesthetic, bonded crowns. They are mostly used for front teeth because they are the most natural looking type of crown and are often used in 'cosmetic' dentistry. There are many types, but they all have a common feature - no metal. They can occasionally break, but dental technology has advanced far enough to make them quite strong.
This is most common type of crown and has a proven track record. PFM crowns are fairly aesthetic and they look like real teeth. However, the margins or borders may appear dark because PFM crowns have a metal substructure with layers of porcelain fired over the substructure. Porcelain is very hard, much harder than natural enamel and may cause excessive wear of the enamel of opposing teeth. Porcelain may break with extreme biting forces.
The 'gold' standard. Dental gold is about 60% gold alloy which is meant to match the hardness of the enamel of opposing teeth so both wear about evenly, an important trait. Gold does not tarnish or corrode and has some bacterial-inhibiting quality. Gold crowns are strong and will not break. However, gold crowns obviously are not considered aesthetic; they are gold colored. Usually, gold crowns are used for lower back molars because they aren't as noticeable.
