Letters: Amalgam doesn’t ‘go away’

October 19, 2015

I have read with interest the varying viewpoints, pros and cons of amalgam restorations. After nearly 40 years of practice, my observation is this: Composite restorations go away. Amalgams may wear a bit but they don’t “go away.”

Large posterior resin restorations wear away, get cupped from opposing cusps and can lead to changes in occlusion due to the material actually wearing away. I have been alarmed by the changes I have seen in mouths that were entirely rerestored with large posterior composites.

If all occlusion is supported by opposing good enamel then I believe it is safe to use composite with monitoring. If not, amalgam, inlays on a crown may be indicated.
