What is Composite Filling?
A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out the cavity with a filling material.
By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-coloured fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).
How does the composite filling procedure work?
The procedure for a dental filling is used to repair minor fractures or decay in the teeth, as a form of restorative dental treatment.
The first step in the dental filling procedure is to administer a local anaesthetic so that the area around the affected tooth becomes numb, increasing the comfort of the patient throughout the procedure the decayed or damaged tooth and its surrounding areas should be prepared for restoration. A dental hand-piece or laser may be used to remove the damaged parts of the tooth.
The placing of a composite filling requires isolation of the affected tooth; this aims to prevent any interference by allowing moisture in the bonding process in the composite restoration.
