Do thin veneers like lumineers fitted to teeth with no shaving make the teeth look thick ? Are they always preferable to standard porcelain veneers which involve shaving off more of the tooth ? Please can you advise the pros and cons of standard veneers versus the new thin veneers currently available. For long lasting, natural looking stain resistant teeth, which of the market leaders such as lumineers, mac or da Vinci do you recommend please ?
