The most efficient and long-lasting way of enhancing a smile is by using wafer-thin stain-proof shells of ceramic (lithium disilicate) or Composite which can be bonded on the front/visible surface of your tooth. This can be understood by imagining veneers as contact lenses for your teeth. They change the way a tooth appears in terms of size, shape and colour and can transform your smile into one you only dreamt of till now.
