Mitigating mouth noise is simply a process of breathing through your phrases. The moment you stop the air flow is when mouth noise occurs. If you're mindful of breathing through phrases, you'll virtually eliminate mouth sounds. Add a noise gate in post and you'll have cut down on your editing time significantly.
