No.  When Dr. Jim Canarsky began his dental practice, silver fillings were considered the standard of care, but due to changes and improvements in technology, they are now highly inferior to bonded white fillings.  It is now known that as silver fillings age, they will leak bacteria or decay around the edges and often times it will not be detected until the decay is quite large and perhaps a root canal is necessary.  The second more serious problem with silver fillings is that since they are metal, they contribute to teeth cracking and breaking.  Usually the only way to detect leaking decay or cracks is by visual inspection with an intra-oral camera.  If you have silver fillings and have not had this done yet, Dr. Canarsky highly recommends this.  Problems are always better treated sooner than later.
