Lumineers is a specific brand of porcelain veneers, which use a patented porcelain material known as Cerinate. They are even thinner than traditional veneers.
Lumineers require very little or no tooth reduction. They are a great choice if your teeth only need minor changes and if they are set back slightly.
Traditional veneers may be a better choice if you are looking to make more dramatic changes. Always ensure that your cosmetic veneer dentist has a proven history of these types of procedures.
