עבריתLumineers, a type of no-prep veneer, are ultra-thin, custom-made shells of porcelain that are bonded directly to the front surface of teeth without requiring any removal of tooth enamel. Unlike traditional veneers that involve shaving off some enamel, Lumineers—typically around 0.2 mm thick—preserve the natural tooth structure, making the procedure minimally invasive and often reversible.
