Porcelain veneer is a thin layer of material that is cemented onto tooth surface to change the shape and colour of the tooth.
It provides superior esthetic compared to composite veneer and is relatively easy to take care as it does not stain.
The colour of the veneer can be selected according to preference.
However, as porcelain is brittle, biting on hard food will cause it to chip and it may need to be replaced.
Other than that, the tooth receiving the veneer will need to be reduced in size in order to allow for thickness of the material, as well as to mask any discolouration of tooth beneath the veneer.
Porcelain veneers generally last for 5-10 years depending on care as well as diet.
To protect the veneers, it is advisable to wear a night guard during sleep to prevent accidentally biting off the veneers.
