Silver Fillings Last Longer than White Fillings

In my last two articles, I addressed the length of time that White (Composite or Tooth-Colored) fillings last and the length of time that Silver (Amalgam) fillings last.

In this article, I simply wish to summarize the results and show a graph comparing the length of time that you can expect your fillings to last.

Amalgam (Silver) Fillings Last Longest

Amalgam fillings tend to last around 12 years, while a composite filling only lasts about 6 years.

Here is a graph that shows the percentage of remaining fillings after a certain amount of years.  It has been constructed using the data from Chadwick B, Dummer P, Dunstan F , et al. The Longevity of Dental Restorations.

Does This Mean Amalgam Fillings Are Better?

A Beautiful SmileNo.  Amalgam fillings are less costly and generally last longer, but they aren’t very aesthetic.  Most people don’t want everyone to see a big chunk of silver on their teeth when they smile.  As a general rule, composite fillings are usually best for the front teeth that most people will see.  For teeth in the back, the stronger, long-lasting amalgam fillings are usually recommended.



  1. quick question.. i got my fillings done about two days ago and on the 1st day a little piece of filling i felt on my tounge and i didn’t really think anything of it so i checked in the mirror and i can’t really tell if it came off in a tight corner or what on my two molers but if i don’t hurt or anything or that sort should i be concerned? plus i will be going back in april… what do you think?

    I generally tend to wait to see if it causes me any problems, if you don’t have any pain then you should be able to wait till April and get him/her to check it for you.
