No there certainly is not.
In fact, gold is probably still the best material to have in your mouth.
It won't crack.
It won't wear down the opposing teeth.
It fits around the tooth exceptionally well.
So why don't people do them these days?
#1 The look.
People simply don't like the look of gold in their smile.
#2 The Cost.
With the price of gold through the roof gold crowns
are about 40% more then the white crowns.
They still can be done upon request.
And any dentist can still make them for you.
They are just kind of a dying breed.
