Is this the end of Silver Fillings?

Tomorrow we are expecting a ruling by the FDA on the classification for "encapsulated amalgam" (that is a cartridge that holds the liquid Mercury and the powder made from other elements). There has been controversy following amalgam for many years. And too often, it becomes the whipping boy for health extremists. In my experience of over 20 years in dentistry, I cannot say I personally have observed or treated someone who has suffered some ill or neurological effect from having silver fillings.

Amalgam has been around for more than 100 years. That was the main material that I was taught to fill teeth with in 1988. Personally, it can work great, but I stopped using it over 10 years ago. There is simply no way to make it part of cosmetic dentistry.

My personal belief is that amalgam persists because it is a fairly easy and forgiving material to put into teeth. In general, you can be a very average dentist or dental assistant and fix a cavity with silver filling. In my opinion, it takes greater skill and ability to place white fillings that produce both a beautiful and comfortable result. You just simply can't have a bad day with white (or composite) fillings because it is a demanding material.

Beyond fillings, lies the realm of porcelain restorations. There are many times that NO filling materials (silver amalgam or white composite) are strong enough. In my cosmetic dentistry practice in Denver, we often use porcelain inlays or onlays to repair teeth beautifully. These restorations can be invisible even to the trained eye and can repair a tooth that has had a larger cavity for many years.

So... we'll see what the FDA says tomorrow.

Actually, in my practice it won't make any difference, since I don't use it anyway. I'll just stick to the great resources that I already have for cosmetic dentistry (visit our smile gallery). We'll just keep on making back and front teeth look natural and smiles looking great!
