Lumineers are made from a special patented cerinate porcelain that is very strong but much thinner than traditional laboratory-fabricated veneers. Their thickness is comparable to contact lenses

—• Lumineers can be placed on the teeth without removal of the tooth structure.

• Patients can receive their veneers quickly, usually within two weeks from the date that the impressions are made.

• Lumineers bond directly to the tooth, making the bond very strong. They are also very long-lasting- up to twenty years or longer.

• Lumineers are a reversible procedure.
