Here’s the ultimate travel toothbrush, the OHSO Travel Toothbrush. It is a type of toothbrush that comes in the shape of a pen where you can carry it around like your pen and can be filled with toothpaste. The toothpaste can be filled at the handle and can be dispensed though the rubber nozzle on the bristle head. It uses suction technology to pull toothpaste into the handle for no mess refilling. Ohso also comes with a replaceable bristle head so you can replace them when they wear out. Travel often? It is available for $19.95.
