Is there a surgery to repair cracked nipples?

I have had cracked nipples for several years now. Bothe my general practitioner and the dermatologist she sent me to said the cracks happened from nipple development a long time ago. I've tried all the creams and techniques they've told me to try. They still haven't healed. I am very tired of being constantly worried that they will crack more or that my cream won't stay on in the shower(the dermatologist told me to put some on before going in the shower).
