AFAIK, gold fillings might be a good choice if the gold is mixed with safe metals. For cosmetic reasons, many choose to only have it in rear teeth. If you do use gold inlays, onlays, and crowns, make sure to use a dentist that uses gold frequently(perhaps an older dentist?) as proper installation is crucial. AFAIK, gold inlays, onlys, and crowns also need an adhesive. When I asked my dentist about using gold, he said it would be very expensive, and he is not comfortable using it, while he uses porcelain all the time. So I I chose to go with porcelain inlays, onlys, and crowns for the larger fillings, and composites for the smaller fillings(especially when they aren't on chewing surfaces). Some dentists use composites for everything.Composites on the chewing surfaces of rear teeth, especially if they are large, tend not to last very long.

With gold restorations, one has to wonder what the gold is mixed with. I think many dentists that use gold might use a mixture that is less than 50% gold to keep the cost down. I wonder what they mix the gold with. I hope it is not nickel or even something worse(I guess if they use nickel, they will also mix in plenty of copper to keep it yellowish looking).
