Silver Fillings and Mercury-Free Dentistry
What are silver fillings, and why aren't dentists really doing them anymore?
Silver fillings were really the standard, I would say, 30 years ago. That was typically the material that was used. It had its place in time in dentistry, but at this point, we have really moved on to resin material, which is the white material that looks more like your teeth.
What are amalgam fillings?
Typically also called silver fillings, they are a combination of silver, tin, and copper. The most controversial part about them is mercury. Mercury is found in a minute amount within the silver restoration. It's mostly used during the mixing process, but once it's placed, there's no active mercury within that silver filling.
Should I have my silver fillings removed?
A lot of patients ask, "Do I need to have my amalgam or silver fillings removed?" If you are not having any issues with your restoration or there's no cavity underneath it, there's no real point in removing it. If you don't like how it looks, sure, we can take it out.
How does a dentist remove silver fillings?
We typically place a rubber dam, use high vacuum suction, drill, and remove them. We try to take them out in as large pieces as possible to reduce the amount of residue within the patient's mouth.
When did dentists stop using mercury fillings in general dental practice?
Silver fillings really fell out of dentistry probably about 30 years ago. They really started to transition them out of practice. It became popular to use composite or tooth-colored fillings. Patients find them much more aesthetic.
There are always pros and cons when using a silver filling versus a composite filling. Silver fillings tend to last longer, but we also see more cracks within teeth with those silver fillings or discoloration. Composite fillings have great realistic coloration that matches your teeth, but we place those more with reliance on the bond to the tooth, so we tend to see those fail over time more quickly than the silver fillings.
