Most of us know that we should brush and floss daily but most of us never think about cleaning our tongue properly or using a tongue cleaner. The tongue can host many types of bacteria and can also be part of the cause of bad breath. The tongue contains many crevices and areas where bacteria can hide so regular cleaning is required. Due to the uneven surface of the tongue, it is easy for bacteria to hide and can be challenging to clean if the right tools are not used.
