How to Brush Teeth Without a Toothbrush. If you're like most people, you can't leave the house in the morning or go to bed at night without brushing your teeth. If you're ever stuck without a toothbrush, however (perhaps you are camping, or forgotten to pack one while traveling), you can brush your teeth without a toothbrush. In a pinch, at least, you can get your teeth clean enough until you can find a toothbrush.
Wash your hands thoroughly. With your forefinger still wet, rub your finger over the teeth and gums on one side of your mouth. Rinse your finger and repeat on the other side.
Wet the end of a paper towel. Wrap around your fingers and rub over your teeth and gums in small, circular motions. Work front, back and top of teeth to remove as much buildup as you can.
Rinse your mouth vigorously with clean water. Swish water over and through your teeth as forcefully as possible. Spit water out and repeat as many times as it takes for your teeth to feel clean.
Use mouthwash. Many brands of mouthwash now contain fluoride and teeth whitening agents. If you are without a toothbrush but have mouthwash, "brush" your teeth by swishing some mouthwash over your teeth.
Carry a product called Floss & Wipe© wherever you go. This will come in handy if you have forgotten your toothbrush while traveling. Simply open the package and use the handy floss and soft cleaning cloth combination to clean your teeth.
