How to Prove a Gold Crown Has No Silver in It

Dental gold is a popular commodity in dental offices. Used to fabricate gold crowns and bridges,dental gold is not 100 percent gold. The reason for this, is that gold is notoriously soft and could not survive being in a mouth -- doing the job it has to do -- without other metals such as silver, zinc and copper. Dental gold is approximately 80 percent gold, the rest is made up of other metal alloys. It can't be proven not to have silver because it does have silver to some degree.

  Do some online research with regard to what dental gold is made out of. Some dental gold is 14k to 22k base gold. However, to give it the strength to withstand the human bite, it must be cut with different harder metals.

• 2

  Take your dental gold to a gold merchant, if you have dental gold that is no longer in your mouth. He has equipment to test the gold, after he uses a grater for metals and tests it. Dental gold still has value, even with the other materials incorporated. Most gold buyers will buy old dental gold.

  Get second opinions from other dentists, if there is a reason silver in the gold is not wanted, perhaps there is an allergy to silver, it would likely not bother someone as part of a crown, but it would be necessary for you to seek another's advice, just to reiterate the facts on gold dental work.
