The new plastic and ceramic fillings are better because they're harder and more durable but there are situations such as pocket caverns in which amalgam is the only way to go. The resins also can't take the pressure of molar surfaces so unless you can afford the ceramic (and many can't), it's gotta be amalgam. The only "good excuse" for pulling functioning amalgam fillings is vanity
the new resins/plastics are not as porous as the older materials, but they are not as flexible as Amalgam fillings. There is still alot of patients that complain that the new filling materials are longer sensitive to cold/temp change. Also with Amalgam you could carve the filling better, you do not get the same occlusion with the new materials, therefor it can throw a bite off.

How long do amalgam fillings typically last before they need to be replaced? I've had mine for 28 years.
An Amalgam filling lasts 8-10 years, then usually some microleakage starts, if they are still good and no leakage- you had a good doc place them.

Curiously once I left school & became a student things much improved (maybe nothing left to fill...)
you are no longer in the Dental Caries risk age, as you get older the saliva changes, its not as acidic- leading to cavities, but more basic, leading to formation of calculus/tartar/zahnstein, and you are at a risk for Periodontal disease. The caries you are at risk for are around the margins of the old fillings, or on the newly exposed roots.

Amalgam is what it says, it's a mixture of different elements,
exactly, a filiing is 50% Mercury and 50% Metal Alloy (Silver, Nickle and a few other trace metals)

I went to a dentist and she said that gold was the way to go. Apart from the obvious bling value it wears better with the teeth around it, or something.
Gold is by far the best. One of my bosses has been in business for over 30 years, and many of those patients still come for cleanings, and those Gold fillings, inlays, onlays and crowns are still doing good!
Now, some people are sensitive to Mercury or Nickle, fine, get the allergy tests done and never eat Tuna again. Alot of it is pyschological, something you have to learn from the patient on their first visit and learn to work with them. We do forget how powerful the brain is.
