Gold is used under porcelain bridges and crowns for strength.  It is generally compatible with humans.  It is important to get a high quality of gold, 75% and above.  Some people have allergies or are reactive, so to be sure, they can get a biocompatibility report.  As far as fillings, it is not as desirable as white fillings because of asthetics.  There is also the factor of heat and cold transference.  Gold fillings can conduct the heat and cold, causing sensitivity in some teeth.  Gold, like mercury and porcelain, does not adhere to teeth well and much more drilling is required to put one in as opposed to a composite;  Thus, for small to medium fillings, they would not be a good choice, unless you do not mind the extra tooth being taken away.  Gold and porcelain are considered permanent restorations and are good for bigger fillings and can last 20 to 30 years and longer.  Composites stick to teeth very well and do not require much drilling;  They last 5 to 22 years, depends on the brand and the patient's habits, etc....   They are the most desired by patients for small to medium-sized fillings.
