Is It Safe to Remove Silver Fillings?

I suggest to remove them only when needed in the case of decay or cracks. For several reasons:
1. Old fillings once removed can cause teeth to become sensitive, possibly needing root canals and crowns
2. We use high speed suction when fillings are removed to capture the debris.

Yes, it is true, some mercury does disperse while removing silver fillings. If a patient has a silver filling and it is doing just fine I advise them to leave it and do not replace it.
I do advise to have a silver filling replaced when there is decay, leakage and when the filling and tooth are breaking down. When we remove silver fillings we use a large suction to remove excess material. There are some natural remedies that may be good to take before and after having a silver fillings replaced, such as cilantro and vitamin C.
