My mouth often feels dry and sticky when I'm not feeling well. On those occasions, I use Tantum Mouthwash after brushing my teeth in the evening and before going to bed. It leaves my mouth feeling refreshed and provides perfect oral sterilization, making it excellent for preventing mouth sores. Gargling all the way down to the back of the throat and spitting it out is also effective for preventing tonsillitis. The small bottle size makes it perfect for carrying around.
