Dental Crowns

Dental crowns are a form of tooth restoration. Crowns can improve the strength of existing teeth that have weakened as a result of an injury, wear or extensive decay. They can also be used for aesthetic reasons to cover teeth that are poorly shaped or noticeably discolored. A root canal, a common procedure that removes diseased nerve tissue, is sometimes performed when a crown is recommended.

Because all crowns are custom-made in a laboratory, you will need to visit us at least twice to complete the procedure. During your first visit, we will prepare your tooth, as necessary, and make a mold. At the second visit, we will permanently seat the crown and attach a dental bridge if indicated.

Dental crowns are available in a choice of restorative materials. If you are a candidate for a crown, here are some points to consider when making decisions about your restoration.

All-Porcelain (Ceramic) Crowns

All-porcelain crowns look the most like natural teeth and, with adequate thickness, are very durable. However, they are susceptible to fractures and may not be the best option for molars and other teeth that must handle impact and strong chewing pressure. Porcelain crowns can wear opposing teeth if their surface becomes rough. Patients with porcelain crowns sometimes require additional followup visits for tooth color-matching purposes.

Porcelain-Fused-to-Metal Crowns

In this crown, porcelain is bonded to a supporting structure of gold or base metal to create a much stronger restoration. It is ideal for use in heavy chewing areas. In some cases, it may be necessary to remove more of the natural tooth in order to accommodate the new crown. With fused and all-metal crowns, some patients may experience temporary sensitivity to hot and cold foods.

Gold Alloy Crowns

First introduced in the 1800s, gold alloy crowns are made from a mixture of gold, copper and other metals. They stand up best of all to high impact and heavy chewing, and they are resistant to fracture and wear. Though gold alloy will not tarnish, its appearance may not be suitable for those who prefer a natural look.

Base Metal Alloy Crowns

If budget is a consideration, a base metal alloy crown with a silver appearance is the least costly alternative. It is very similar to gold alloy in durability, strength and function.

Dental crowns come with either a one- or two-year warranty on workmanship. During the warranty period, we will repair any damage or defects at no cost to you provided that you visit our office for a routine examination every six months.
