Dental veneers are porcelain shells that are stuck permanently onto your teeth.Why use dental veneers? Dental veneers are used to change the shade of your teeth, if traditional tooth whitening does not have the desired results. They can also be used to improve the alignment of your teeth, which includes filling gaps. We use two types of materials for the veneers. Veneers can be made using composite or ceramic. Composite veneers are cheaper and have a different appearance. The have a life-span of 5 years. Ceramic veneers consist of several layers of cosmetic ceramics, which form a thin film. They have a long life-span than those made from composite materials.
