The answer from the dental community has been "Not Much". There is no conclusive evidence that the amount of Mercury contained in a dental filling can hurt you.

"Mercury poisoning" is an imprecise term that can apply to numerous symptoms associated with absorption of mercury. According to the FDA: "FDA has reviewed the best available scientific evidence to determine whether the low levels of mercury vapor associated with dental amalgam fillings are a cause for concern. Based on this evidence, FDA considers dental amalgam fillings safe for adults and children ages 6 and above. The amount of mercury measured in the bodies of people with dental amalgam fillings is well below levels associated with adverse health effects. Even in adults and children ages 6 and above who have fifteen or more amalgam surfaces, mercury exposure due to dental amalgam fillings has been found to be far below the lowest levels associated with harm. Clinical studies in adults and children ages 6 and above have also found no link between dental amalgam fillings and health problems."
