When you're in the wild, tears in backpacks, tent seams or clothing can go from a small problem to a big one pretty fast. Dental floss is strong enough to be used as thread for temporary stitching. A basic sewing needle or even a sharp thorn can work to push it through fabric.

It's not a permanent fix, but it'll hold long enough to get you through the trip or back to safety.

Dental floss can cut soft foods like cake, cinnamon rolls, brownies or soft cheeses much more neatly than a knife. Simply hold a long piece of floss between both hands and pull it through the food in a gentle sawing motion.

Since floss is thin and smooth, it glides through without crushing the texture, giving you bakery-style slices every time. Just make sure you use a non-flavored type, so no minty taste is left behind on your food!

Dental floss can help remove stubborn price stickers or labels from glass jars. Slide the floss underneath the label and gently pull it back and forth. It cuts through the adhesive layer and lifts the sticker away without scratching the surface.

In areas where wildlife is a concern, hanging your food away from camp can protect your supplies and reduce the risk of an animal attack. Dental floss can be used to hang lightweight bags of food from tree branches.

ADVERTISEMENT

You'll need to toss a rock or stick tied to one end to loop it over the limb of a tree. It won’t hold large amounts, but for small kits, it's a helpful last resort to keep critters away.

Gardeners or home plant lovers can use dental floss to tie plant stems to stakes or trellises. The thin material keeps them upright without adding bulky ties, and it can easily be cut away later when the plant grows stronger.

Dental floss can help remove a ring that’s stuck on your finger. Slide it under the ring and wrap the longer end around your finger toward the tip. Then gently unwind the floss while pulling the ring over it.

If you work with clay or baking dough, dental floss is perfect for slicing it into clean portions. Potters often use a similar wire tool.

If you're in a situation where you need to catch your next meal while out camping, floss can act as a substitute fishing line. It's thin, nearly invisible in water,and strong enough to handle small to medium-sized fish.

Tie a hook or even fashion one from a soda can tab, paperclip or thorn. Add bait and drop it into a stream or pond. It's not perfect, but when your options are limited, it can help put food on the proverbial table.

Clean Small Spaces

Shoelaces break more than you'd expect, and losing one while out can make walking difficult. Dental floss can be braided to form a strong enough replacement to keep your shoe snug until you’re able to get new laces.

The same applies to securing gear like rolled-up tarps or keeping tools tied to a pack. It’s not ideal for long-term use, but it works when you need something fast and functional.

Starting a fire with a bow drill is hard enough without worrying about cord failure. Dental floss, when braided or doubled up, can serve as an emergency bow string, as it's durable enough to create the friction needed to start a coal.

While it won't last as long as paracord, it’s good for a few attempts and may be all you need to get a fire going in damp or cold conditions.

Dental floss can help dislodge food caught in toaster or blender crevices, at slides into tight areas to remove trapped crumbs. Just make sure the appliances are unplugged before you attempt this, as not doing so risks an electric shock.

There's nothing worse than going into your freezer to grab food, only to find it's stuck together and you need to portion it out. Instead of waiting for it to defrost, you can use dental floss to separate them.

Slide the floss between the pieces and pull gently to break them apart.

Strong cordage is essential for building a shelter, especially when tying together branches or securing a tarp. Dental floss can act as backup lashings if you run out of or lose your paracord. You can even use multiple strands twisted together for extra strength.

While it won't hold up long under heavy weight, it does the job in a hurry and holds tight in dry conditions.

Injuries happen, and when they do, keeping a wound stable or covered is crucial. If you're out in the wilderness and far from medical care, floss can help tie splints in place when you have nothing else. It also works to secure bandages or even makeshift slings.

It's not the most comfortable material, but in emergencies, it can hold things together until you reach proper help. If nothing else, it keeps pressure on a dressing when time is critical.
