Why do filling break down?!


Question: Why do filling break down!?
Answers:
Amalgams tend to break down due to what is called leakage!. Unlike the white fillings, these fillings are mechanically boded to the tooth, not chemically!. Although they last longer, silver fillings will leave a metal like taste when they begin to breakdown!. The white fillings are boded with chemicals making it less likely for leakage, but more susceptible for stain and chipping!.Www@Answer-Health@Com

filling can be amalgam or composite or gic etc
amalgam tends to break due to either inappropriate cavity preparation or faulty manupulation of amalgam , inappropriate contouring ,larger restorations,microleakage
for composites inadequate bondig due to improper curing, in areas of high occlusal stress!.
gic restorations also break due to improper manupulation or adhesion!.Www@Answer-Health@Com

it s like anything else, after awhile all the wear and tear on it breaks it down, just go back to the dentist to have it repaired!.Www@Answer-Health@Com
