I have fillings in my front teeth, I need a solution. Some doctors told me veneers, some told me eMax crowns?

So I have fillings in my 6 front teeth, and every year or so it gets yellow or changes colors and it really bugs me. I keep changing the fillings every year until the last doctor made a huge gap between my front teeth while removing the filling. I consulted many doctors some of them told me veneers, some of them said no it will eventually fall. Others said just get emax crowns, but I don't want to file down my whole teeth! What should I do in such situation?! :( I want a permanent solution.
