Hello, I'm a 26 year old female from saudi arabia . I've just placed 10 teeth zirconium crowns on my upper teeth but I'm not happy with the result the look too white and bulky and fake . they don't look good against my olive skin color . I was wondering if I could improve it . When i complained to the doctor he said that the only way to fix them is to break them and risk losing what left of my teeth.Can having lumineers help with the color and shape?
