Are Old Silver Fillings Safe?

There’s no controversy that has plagued the dental world more than the issue about the safety of dental amalgam. When studies from long ago established a relationship between thyroid problems, neurological disorders, respiratory diseases, and mercury in amalgam, people just went on panic mode. Since silver fillings were popular for preventing the spread of cavities due to their impressive durability, many grew greatly concerned that the restorative dentistry procedure they had was “killing” them.

Do people really need to be worried?

After all, fillings are so small.  “Are old silver fillings safe or are they making patients highly prone to everything from neurological issues, autoimmune disease, chronic illnesses, to mental disorders?”

Here are the facts that everybody concerned about this issue should understand:


  • It’s true that amalgams are 50 percent mercury but they were always considered inert (chemically inactive) so the likelihood or mercury release was none to very minimal.
  • When it comes to mercury leaking from amalgams and producing a toxic effect on the body, different variables come into play (like the age of the fillings, one’s diet, the tendency to grind teeth, and number of fillings one has). It’s never just a matter of “having” silver fillings.
  • More studies are being carried out in order to fully establish the impact of mercury in silver fillings on people’s wellness. So far, findings have been inconclusive.
  • The current ADA and FDA position (because of all the inconclusive results) is that amalgam is a safe restorative material. Therefore, any dentist who recommends removing amalgams due to health concerns from mercury vapor is deemed unethical and could have their license revoked.
  • If you’re concerned about mercury release from your old dental fillings, a lot of dental professionals have advanced detection techniques that can measure mercury release. Hence, they can establish if your health is truly at risk.
  • The highest amount of mercury exposure from silver fillings occurs when they are placed and when they are removed from our mouths. So, if you’re worried about exposure, the smartest thing to do is to have a highly experienced dental team inspect your fillings to see if they’re still structurally intact, instead of just rushing to have them taken out.

It’s only natural to look after your health. Whether you want to have your old silver fillings removed just to be safe or not is completely up to you. Now, if you need to have some cavities filled, there are other filling options to choose from and you won’t have to worry about mercury exposure.
