A. It sounds as though you have tetracycline staining on your teeth. Quite right, it is due to medication from when you were younger. Veneers is a god option for you to mask the teeth. It does however, depend on how dark your eeth are. Veneers have a degree of translucency- so you may want to try whitening first to lighten yoyur teeth as much as possible first to avoid any shadowing coming through the veneers.. Ask your cosmetaic dentist for more details. hope this has helped.
