How do I show my dog he upset me?

He really upset me today, he broke all the rules I've been trying to get him to understand plus he started baring his teeth at me when I stopped him from going through the bin. I'm genuinely upset I never hit or lay a hand on him for punishments so I don't understand why he'd do that? Is there any way for me to show him that I'm really upset with him?
