Composite resin is the most commonly used ‘white’ filling material. It can be used for a wide range of applications, from fillings; to rebuilding small chips; to full veneers on front teeth. Composite fillings have been used successfully on front teeth for decades, and the technology has continually improved. Like all restorations, it is possible for a white filling to fail, and eventually require repair or replacement, but they can last many decades, or a lifetime.
A more recent development has been the use of composite for full or partial veneers. The range of applications is very broad, and in the right hands can offer excellent, permanent results. Crooked teeth, discoloured teeth/fillings, and gaps are the most common cosmetic complaints where composite veneers can be applied.
The method usually involves no need for any drilling of the teeth, and hence anaesthetic is rarely required. The dentist uses a range of available shades of plastic to ensure a great colour/shade match with the neighbouring teeth. And the beauty is most treatments can be completed in a single sitting. A review appointment is sometimes made for a few weeks later.
Are they better than porcelain?
In many ways they are, but in others, no.
As the teeth are not traumatised in the process, they are not weakened, and there is no chance of damaging the nerve. The treatment is wholly reversible, unless the underlying tooth has been modified for some reason. Also, should the dentist make a mistake with the colour/shape, both can be easily modified/redone at the review appointment. With laboratory made porcelain, this is more difficult, as the lab technician does not have the actual patient to work with.
However, there are limitations.
Composite veneers do require skilful, careful placement. If done poorly, they can develop a stain at the tooth/composite margin. These stains can take a few years to develop, and if they do, the stains can be either polished out or repaired, with the rest of the veneer unaffected. There is a limit on the length that the veneers can be made to. As plastic wears quicker than tooth, tooth to tooth contact should be maintained, and thus lengthening teeth with this type of veneer may be unwise. In order to restore length to shortened teeth, it may be necessary to use porcelain veneers instead. Also, it is generally not recommendable to replace existing porcelain work with composite.
Much like porcelain, composite veneers do not change shade with whitening treatments. Hence, any desired whitening is best completed PRIOR to placing veneers of any kind, to avoid the need for replacement veneers.
