Large black amalgam fillings normally require replacement at some point in time, otherwise they might fracture or leak.
Apart from being unsightly, they become rough and dark due to metal tarnish.
White fillings are an excellent way to return the tooth to its original colour and shape.
White fillings could be applied directly (composites) or are laboratory precision manufactured.
In some cases, large cavities in molar teeth can be restored by using laboratory-made porcelain fillings or onlays.
These can result in amazing looking teeth that make them indistinguishable from natural tooth enamel.
They are best suited to molars having moderate to large amalgam fillings.
