So you have made your ultralight toothbrush spoon but are still lugging around all that heavy toothpaste or painfully drying it. You should know that tooth powder is a thing (and has been for a long time).
You can even buy your favourite brand (Colgate). Some studies even show that it is better for cleaning your teeth – as well as saving you a few grams. What’s not to like?
Dental floss is also a useful product. I carry it for repairs (using a self-threading needle). I have sewn up a pair of trousers which practically split in half with it on the Dusky Track – and you can even catch a fish with it.
