Amalgam vs Composite – Which one is better?

Amalgam is the old style of dental restoration and is a very strong material that can last decades. There is much concern and controversy about the mercury in amalgam fillings and when people develop health problems, it can be difficult to isolate the cause. One research from Anglen in  2015  indicated that the occupational exposure to Hg from amalgam may increase the risk of tremors in practicing dentists. More studies of tremors, as well as sclerosis among dentist, are needed to confirm these findings. so amalgam can affect the health of those who deal with the material. At the moment, research is ongoing as to how it affects patients.

Many dental professionals believe that amalgam is stronger than composite, and that is somewhat true. One research from Laccabue in 2014 showed that there was no difference in the rate of replacement for amalgam versus resin composite. Amalgam itself is a stronger material than composite but it is not an advantage to use a stronger material than tooth itself. It is common for teeth with amalgam restorations have crack lines due to prep design and the amalgam itself being stronger than the tooth structure. Teeth filled with composite can also develop cracks, but it is less common.

Another research from Opdam in 2010 showed the caries risk of patients plays a significant role in restoration survival. In the high-risk group, composite and amalgam restorations showed comparable performance, but in the low-risk group, composite restorations showed better survival at 12 years. So if you have amalgam restorations, replacing to composite is not necessary but you might need to replace to a  crown due to the tooth breaking down around a large amalgam restoration.  If you have old amalgam restorations in your mouth, it is advised to get checked as amalgam also can mask decay In x-rays.   One research from

So if you have amalgam restorations, replacing to composite is not necessary but you might need to replace to a  crown due to the tooth breaking down around a large amalgam restoration.  If you have old amalgam restorations in your mouth, it is advised to get checked as amalgam also can mask decay In x-rays.   One research from Koker in 2004 indicates that the odds of teeth with large amalgam restorations receiving a catastrophic treatment being 2.1 times the odds of teeth with crowns receiving catastrophic treatment.

Before it gets worse, or breaks,  it is wise to get checked by a dental professional.
