Fillings

Direct restorations are fillings that we place into a prepared cavity in a single visit.  This type of restoration includes dental amalgam and composite (resin) fillings. 

Amalgam Fillings
Dental amalgam, used in what is commonly referred to as a ‘silver filling’, is a compound of mercury and other metals.  It has been successfully and safely used for over a century; although some concerns have been raised about its mercury content, the mercury in amalgam chemically combines with other metals to render it stable and safe.  Amalgams are useful for their strength and durability, and can be especially beneficial in situations where restored teeth must withstand extreme amounts of pressure, most notably in the back of the mouth. 

Composite Fillings
Composite fillings are a mixture of acrylic resin and finely ground glasslike particles.  This combination produces a tooth-colored restoration.  These fillings are durable in small to mid-sized restorations, withstanding moderate chewing pressure.  Composite fillings require the removal of less tooth structure, which can result in smaller fillings.
