The halita tongue cleaner is specifically designed to reach the most inaccessible areas of the tongue. The tongue is the place in the oral cavity where the greatest amount of bacteria accumulates. That is why it is very important every day to remove bacterial film and food debris that build up on the tongue. This will prevent the proliferation of anaerobic bacteria that produce malodorous gases. It has two sides, one with a ridged surface and the other with a flat surface.
