Backcountry Hygiene for Ultralight and Long-Distance Hikers

"Long distance hikers are prone to poor tooth and gum health. The physical stress of a long distance hike places tremendous demands on the body’s immune system, and teeth and gums are some of the first areas to suffer. That, combined with general laziness among hikers when it comes to flossing and brushing their teeth, can lead to serious problems over the course of a few months on the trail."
