There are many different things that are found within dental gold. The big misconception is that gold when someone talks about gold being within a crown or a filling that it is 100% gold and 99% of the time that is incorrect. Typically gold is predominantly the most important metal found within the gold crown or tooth, however, it actually represents what is called an alloy. An alloy is a combination of metals used to make the metal stronger and possibly better fitting or even more cosmetic and for that reason you will find that within dental gold typically gold only comprises of about 60 to 70 maybe about 80% of the actual tooth, crown, or bridge. What you actually find is that because it is an alloy it contains other metals in addition to that such as silver or tin or copper and even sometimes like palladium or titanium. Basically though with any sort of gold tooth there is a combination of different things. Gold again is the predominant metal found within that unit but there are other metals added to it to again add to the cosmetics and the strength and longevity of it.
