I have these white gross things on the back of my throat?

When I take them out , i use tweezers and just pluck them out and it smells terrible... I think its triggered by dairy pt orducts liek yoghurt or milk so i just dont have that much anymore. But I was wondering if i take them out , brush my teeth , chew gum and gargle salt water do you think I can still kiss? Or would the person smeell it still...Im so self concious of this ! PLEASE REPLY !!!!!
