Lumineers offer the painless way to a permanently whiter and perfectly aligned smile. Lumineers are a brand of porcelain veneers. Lumineers are tougher than most other brands of porcelain veneers and, therefore, can be made very thin. It is generally recommended that porcelain veneers be made a minimum of 0.5 millimeters thick, about the thickness of a fingernail. For Lumineers, they can go a little thinner, down to 0.3 millimeters. Since they are so thin, the teeth don’t have to be “ground or shaved down” and they can be placed directly over unprepared teeth without being too bulky. Lumineers can even be placed over existing crown or bridge work without having to replace them. The proposition of no shots or drilling and the fact that they are reversible is very appealing to most people.
