ATLANTA -- It's a grainy substance, sprinkled from a dispenser onto your moistened toothbrush. Powdered Toothpaste Substitute might not make your pearly whites shine brighter or whup cavities any better than the standard gel.

With most nonsolid substances banned on flights, makers of personal items for such body parts as teeth and nails are fighting tooth-and-nail to promote available alternatives. Or in the case of Travelon, a product design firm in Elk Grove Village, Ill., specializing in luggage goods and accessories, rush out fresh items.
