A veneer is a thin covering made of porcelain, ceramic or composite which is placed over the front, visible part of a tooth to enhance its appearance. They are often used in smile makeovers.
Veneers are used on teeth when minor changes in the size and shape of teeth are needed. Veneers can be placed on front teeth that are poorly shaped, slightly crooked, chipped or worn. Veneers may also be used to lighten teeth that cannot be whitened by bleaching or to close gaps between front teeth.
Because they are very thin and bonded directly onto the enamel, the underlying tooth structure should be sound and healthy.
