Composite filing materials (used for most white fillings) have developed hugely in the last few years and are now used as the preferred technique of many cosmetic dentists.
Composite build ups or layering can use a whole range of colours of material and densities to mimic natural teeth. In our case we use 3M Supreme material. The technique is very dependent on the skill and the 'eye' of the dentist as no technician is involved. The changes can be made in one visit and do not usually require impressions. Again because there are no associated laboratory charges (as there would be with crowns or veneers) the costs can be considerably lower.
