Even after brushing my teeth twice a day, my mouth still smells terrible. What can be done to prevent bad odour from mouth?
Bad breath (Halitosis) can persist even after brushing if caused by tongue coating, gum problems, dryness, or digestive issues, so clean your tongue daily with a tongue scraper, floss regularly, and stay well hydrated. Use an antibacterial mouthwash and avoid tobacco, excessive coffee, and strong-smelling foods. If the problem continues, visit a dentist to check for gum disease or cavities and get proper treatment.
