I had bulimia for years as a teen as well as a grinding habit. I'm looking for a way to enhance my smile so I'm not so insecure about it anymore. I have some craze lines on my front two teeth and lower front teeth (as well as mild erosion on the bottom front two). I am afraid of veneers since I want to be considerate of my natural tooth health. Would cosmetic bonding be possible? Would zoom whitening hide the cracks?
