Can upper crooked teeth be straightened without correcting the underbite? I have been advised surgery to fix underbite and I am terrified with the idea of having to go for a surgery (I read lots of negative reviews of surgery and the pain it comes with)...So I was hoping that I will just go for braces to get straight teeth and skip surgery altogether..Will that be possible? Will not going for surgery affect the straightening of teeth? Please suggest.
