What type of metal is in your dental crowns?

by Dr. Fred Peck, DDS 7. July 2011 06:45

What type of metal is in your dental crown or "cap" as commonly known. There are 3 types of metals that dental labs use most often. The first is called a high noble metal. This has a high percentage of gold and other precious metals. Often this metal is used under porcelain crowns and bridges as are other types of metals. This is a high quality metal with almost no side affects. Then next type is a noble metal. The percentage of precious metals is greatly reduced. Some patients may have some irritation to the gum tissues, but this is also rare with these metals. The last is a base metal. They may contain metals such as nickel and beryllium, among other types of metals. Many people have allergic reactions to these metals and should really be avoided because of metal toxicity that some patients may experience. Woman often have sensitivity to these base metals. A good test is if a woman has a skin reaction to non gold earing's. If she cannot wear non gold metals, a reaction in the gum tissue may also be seen.

Your dentist should be able to tell you what type of dental materials are being used in your mouth. The metal used, usually returns from the lab with a certificate listing the exact components in the crown. Don't be afraid to ask. If you have any metal allergies, make sure you tell your dentist so he/she can be aware. Crowns can also be made using all ceramic materials, which I will discuss in my next post.

Very few companies have a true certification that is reliable.  Most of the stickers that the products are shipped with can be purchased off the internet and placed on the product being sent out.  What is being done to have some quality assurance that what in fact the dentist receives is what is being placed into a person’s mouth?  I have also learned a lot of the products are being shipped over from Chinese labs and that the FDA has not jurisdiction to inspect those facilities.  Knowing that certain metals can have a major impact on someone’s health why do they not have a process that checks the product being made from start to finish.  If the FCC and track a part on the airplane down to the tiniest screw used on a plan shouldn’t something being put in someone’s mouth be tracked the same way?
