Crowns: Do You Know Your Options?
If you believe you need a crown or if we have already confirmed this fact, you need to understand that there are several options. The most common are gold crowns, porcelain-fused-to-metal crowns and all porcelain crowns. Each has both pros and cons; thus we will work with you to determine which will work best for your specific needs. However, to help you learn more now, here are some facts.
Made from cast gold, this type of crown has been around for over 100 years and is the most successful type of crown. It can last more than 50 years and thus many dentists prefer gold restorations for their own teeth, where cosmetics is not a concern.
All Porcelain Crowns
All porcelain crowns can produce an incredible, life-like appearance. However, because they are made purely from dental porcelain (a type of glass), they tend to be more fragile than gold crowns and may be more at risk with certain high biting forces. Thus they may not be as durable. Porcelain can also cause wear to the natural teeth they bite against. Therefore they are typically preferred for front teeth, rather than back teeth. They have an aesthetic longevity of about 10 years and a functional longevity of about 20 years.
As the name states, porcelain-fused-to-metal (PFM) crowns provide the best of both worlds. They are made of natural tooth-colored dental porcelain that is fused on top of a precious or noble metal (usually gold or platinum). They are stronger than porcelain alone and are a good option for back teeth because they offer a better cosmetic result than gold crowns. This is also true for front teeth, however the gold support beneath the porcelain can compromise its life-like qualities. These crowns also have a proven track record and have been used with excellent results for over 40 years.
