Interview at Jeweler with braces?

I need some honest opinions. I am 25 years old. Have great sales and retail experience. More than 7 years worth. I just got a call from Littman Jewelers and was told I was selected for a job interview tomm. Now, I just got braces on my top teeth today to help correct a problem im having with my bite. My teeth are relativly straight but will this affect my interview. What do Jewelers look for appearance wise?
