Veneers are thin overlays with a thickness of 0.2-0.5 mm, designed to cover the external tooth surface. They are made of composite and ceramics. According to the material they are made off, they are either called composite or porcelain veneers. Porcelain veneers have high translucence allowing the teeth to look natural.
They are used to mask defects such as yellow teeth ( the inhomogeneous color of enamel after taking some medications); to correct irregular singular teeth, abnormal shape of the teeth, chips and cracks on the enamel; and to close the diastemas and large gaps between the teeth.
Veneer producers only prepare the fence of the theeth; the cutting work is done by the dentist. The surface of the teeth are prepared very thin with 0.2-0.5 mm thickness. Prepared veneers are bonded to the surface of the teeth with a special bonding material.
