There are often problems such as discoloration, minor fractures or other similar issues affecting one or more teeth. In such cases, a good option can be composite or porcelain veneers. Both materials are used to alter and improve the appearance of the teeth but with different techniques. The choice of material depends on the specific conditions of each case and the patient’s preferences, if both options are suitable.
For resin veneers, a “white filling” material (composite resin) is bonded on the front surface of the teeth with no or very little localised trimming. This way the colour can be improved significantly and minor to moderate changes in shape be achieved.
The procedure is usually completed in a single visit and this type of veneer can be relatively easily repaired or modified and polished again by the dentist as needed.
When porcelain is chosen as the restorative material, some slight trimming of the teeth is usually required – about 0.5 mm on the front surface and about 1 mm on the biting surface. An impression of the teeth is then taken and the dental laboratory uses it to fabricate the veneers in the agreed-upon colour, shape, and size. Temporary veneers are placed while waiting for the laboratory and in the final stage the permanent ones are tried-in, possibly adjusted and then cemented in place.
With porcelain it is possible to achieve an improved and stable colour and to achieve more extensive changes in shape and size, as the material is more durable than composite resin. However, this type of veneer cannot be repaired or altered; if necessary, the entire veneer is replaced with a new one.
