Tooth restoration is a very common practice in the dental industry. Restoration involves filling cavities, crown and bridge work or molding dentures.
Decay restoration is more commonly referred to as “filling a cavity”. Cavities occur when the enamel and integrity of the tooth begins to decay. Decay will expose the inner pulp of the tooth which can lead to extreme discomfort. A filling is used to replace the missing part of the tooth caused by the decay.
Plastic vs Metal Fillings
There are two very common types of fillings you are probably aware of: composite (plastic resin) and amalgam (metal).
Plastic composite (white) fillings are popular because they can be nearly invisible.
Amalgam restorations are available for use where complete isolation of the tooth can not be achieved, for example, below gum lines. Amalgam restorations are still a great option for our advanced age patients who experience dry mouth (xerostomia) as the silver in the restoration helps prevent new cavities around the restoration.
