Restorative Fillings may be required in dentistry for many reasons, this is a common and simple technique used to repair teeth. The aim of a filling is to restore the form and function of a tooth as closely as possible to a natural tooth. Filling materials are most commonly made of Composite Resin (CR) or Glass Ionomer Cement (GIC), and will be matched to your individual tooth. Some of the most common reasons for requiring a filling include tooth decay, broken, chipped or cracked teeth, discolouration, misaligned teeth and gaps in teeth. As these fillings can be matched perfectly to your tooth colour, they are commonly used for Composite Veneers on front teeth to improve overall aesthetics.
