How would you tell to your close friend that she has a bad breath without hurting her feelings?

bad breath
yolly asked:

I am so afraid telling her that she has a bad breath because I dont want to hurt her but everytime I talk to her or she talk to me I cannot avoid turning my face to my left or right just to avoid the smell of her breath. I use to talk to a person face to face and looking to that person eyes when having conversation coz i think that is the proper way to talk to everyone but when it comes to her I cannot stop myself talking to her not face to face.
