A dental solution that can prevent tooth extraction. A dental crown is a tooth-shaped “cap” that is placed over the tooth. This cap restores the tooth to it’s regular shape, size, strength, and improve it’s appearance. Once cemented into place, the crowns will encase the entire visible portion of a tooth that lies at and above the gum line.
Stainless Steel: These type of crowns are prefabricated and used on permanent teeth primarily as a temporary measure. This crown protects the tooth or filling while a permanent crown is made from another material. For children, a stainless steel crown is commonly used to fit over a primary tooth that’s been prepared to fit it. The crown covers the tooth in it’s entirety and protects it from further decay or damage. Once the primary tooth comes out to make room for the permanent tooth, the crown comes out naturally with it. Generally, stainless steel crowns are used for children’s teeth because they don’t’ require multiple dental visits.
Porcelain-fused-to metal: Dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). Wearing to the opposite teeth occurs with this crown type as opposed to metal or resin crowns. The crown’s porcelain portion can also chip or break off. When compared to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth.
Metals: These include gold alloy, other alloys (ex: palladium), or sometimes a base-metal alloy such as chromium or nickel. For these type of crowns, less tooth structure needs to be removed. Tooth wear to opposing teeth is also kept to a minimum. Metal crowns are excellent at withstanding biting and chewing forces well and most likely will last the longest in terms of wear down. It is generally unlikely for metal crowns to break or chip off. The main drawback to the metal crowns is the color. These are a great choice for out of site teeth such as molars.
All-Resin: These type of dental crowns are less expensive than other crown types. The drawback with these crowns is that they wear down over time. They are also more prone to factures than porcelain-fused-to-metal crowns. Each crown has it’s advantages and disadvantages, so Dr. Gandhi will go over each type with you and discuss which are best for you particular dental needs.
Temporary versus Permanent: Temporary crowns can be made conveniently at your dentists office. Permanent crowns however, are made in a dental laboratory. Temporary crowns are typically made of acrylic or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by a lab.
Preparing a tooth for a crown usually requires two visits to the dentist.
Dr. Gandhi may take a few X-rays to check the roots of the tooth that will receive the crown and surrounding bone. If there is extensive decay or a risk of infection to the tooth’s pulp, a root canal treatment may first be performed.
Before the process of making a crown begins, your tooth and gum tissue will be anesthetized (numbed). Next, the tooth receiving the crown will be filed down along the chewing surface and sides to make room for your crown. The amount will depend on the type of crown used. If a large area of the tooth is missing (from decay or damage), Dr. Gandhi will use filling material to “build up” the tooth to support the crown.
For your second and (most likely) final visit to the dentist, Dr. Gandhi will set your permanent dental crown. This process includes checking the fit and color for the permanent crown. Once everything has been deemed as acceptable and fit properly, a local anesthetic will be used to numb the tooth. Dr. Gandhi will then permanently cement the new crown in place.
Getting crowns is a simple two-step process that yields fantastic results to your overall oral health.
