A toothbrush designed for travelling. Basically, designed like any other toothbrush but at the opposite end of the brush there will be an opening for dental floss. Here is a drawing of our initial idea (http://i.imgur.com/cMGeSZJ.jpg). There will also be the tongue cleaner behind the brush. This is to save space in your luggage, you'll only need to bring this instead of a pouch filled with your toothbrush, dental floss, mouthwash, etc.
