I have mouth odour my tongue usually white the morning how do i treat it?

White tongue is a: coating of debris, bacteria and dead cells on your tongue that makes it look white. This is usually harmless but can be an indication of something more serious ranging from infection to a precancerous condition. Causes include poor oral hygiene, dry mouth, smoking, alcohol use, mouth breathing, low roughage diet. Brush your tongue, use antibacterial mouthwash, see Dentist/Doctor if persists.
