Wear and erosion behind front teeth. Close to the gum there is still some enamel left (white opaque line encircling base of the tooth). The underlying softer and more yellow dentine is visible. Custom made veneer crowns cover and protect teeth, bonded using remaining enamel. Veneer also improved the form of the eroded teeth and filled the gaps. This is the essence of minimally invasive aesthetic and prophylactic treatment.
