How do you avoid smell from mouth?

To avoid bad breath, maintain good oral hygiene by brushing your teeth at least twice a day and flossing daily to remove food particles and plaque. Stay hydrated to help keep your mouth moist, and consider using mouthwash or chewing sugar-free gum to freshen your breath. Additionally, avoid strong-smelling foods like garlic and onions, and consider regular dental check-ups to address any underlying issues.
