Gold is more than a financial commodity or a symbol of wealth — it’s one of the best materials for restoring damaged tooth crowns, the visible portion above the gum line. It’s extremely durable and can last for several decades if properly maintained. It also causes minimal wear to adjacent teeth.
But as new, more life-like materials have come into prominence, gold restorations have diminished in popularity. Dental porcelain in particular, a type of fired ceramic glass that mimics the look and color of teeth, has increased in popularity for use in highly visible areas.
But unlike gold, all porcelain crowns lack strength, tend to be more brittle and can abrade other teeth during biting and chewing. If they break, they can shatter beyond repair. All porcelain crowns are improving dramatically as newer space age materials become available. Historically, though, they are thought of as more unpredictable when used for back teeth; the greater biting forces make them more susceptible to failure than with front teeth.
A Porcelain-Fused-To-Metal (PFM) crown is a hybrid of these two materials that seeks to impart the strengths of both — the aesthetic appeal of porcelain and the durability of gold or platinum. But a PFM crown also has drawbacks: the porcelain surface may still abrade opposing teeth; they can lose their aesthetic appeal if the metal collar becomes visible if gum tissues recede; and they can fail if the porcelain fractures or separates from the metal.
To address some of porcelain’s weaknesses, some PFM variations reduce the amount of porcelain by placing it only on the visible side of a cast gold crown. In addition, other porcelain materials are now coming into use that may be more durable yet just as life-like.
Choosing which material to use for a crown depends on many factors: cost, the location of the crown, and, of course, the patient’s desires for the resulting smile appearance. It all begins with a comprehensive exam: from there, we can advise you on your options and help you make a choice — gold, porcelain or something in between — that’s durable and pleasing to the eye.
