Why do modern dental fillings fallout, unlike the past?
Modern fillings don’t intrinsically “fall out more” than in the past; what has changed is the material , the technique sensitivity , and often patient risk factors , so failures are more noticeable and sometimes more frequent in certain situations. loudfamilydentistry +1 Material change: amalgam vs. composite Older fillings were usually amalgam (silver/mercury), which is mechanically packed into a cavity shaped with undercuts; it’s relatively forgiving of moisture and technique and often lasts decades. pmc.ncbi.nlm.nih +1 Modern fillings are often tooth‑colored composites bonded to enamel/dentin; they are more aesthetic but more technique‑sensitive (they need a very dry field, careful layering, and proper curing) and have somewhat higher rates of secondary decay and fracture, especially in large posterior restorations. loudfamilydentistry +1 Main reasons modern fillings fail or fall out Secondary caries under/around the filling : Recurrent decay is the leading cause of failure...
