NOBS Dental Floss

NOBS dental floss is made to do one job really well: get between your teeth and pull out what your toothbrush leaves behind. Our textured dental floss thread expands on contact with saliva, so it fills the gap between teeth and grabs stubborn debris on every pass. 

It has a natural eucalyptus aroma, is made from five simple materials and comes in a refillable glass jar. NOBS turns a step most people skip into one they actually look forward to.

A complete formulation containing exactly what you need and nothing you don't. From Nano Hydroxyapatite for remineralization to Zinc Citrate for plaque control, every single ingredient has a specific purpose for a healthier smile.

Just 13 Incredible Ingredients

Hydroxyapatite

Hydroxyapatite rebuilds and strengthens your teeth naturally. It works by depositing calcium and phosphate minerals directly into your enamel, matching the mineral composition of your teeth.

Hydroxyapatite (HA)

Xylitol

Xylitol works by inhibiting cavity-causing bacteria, preventing plaque formation, and reducing acid production that leads to tooth decay. It also promotes saliva production, which helps neutralize acids.

Xylitol

Silica and Calcium

Calcium carbonate fights tooth staining while silica dioxide fights plaque and stains, working as gentle cleaning agents. Together, these minerals provide effective stain removal without harsh abrasiveness.

Silica & Calcium Carbonate

Essential Oils

Peppermint provides fresh taste while menthol delivers lasting freshness. Ammonium Glycyrrhizinate from licorice root creates that foamy, squeaky clean feeling naturally.

What Is Expanding Dental Floss?

Expanding dental floss is designed to change shape once it's in your mouth. NOBS floss starts out slim enough to slide between teeth. When it meets saliva, the textured threads expand to fill more of the space between your teeth. That extra surface area lets the floss reach more of each tooth's side wall and grab debris a thin, flat string can miss. The result is floss for teeth that feels noticeably more thorough, especially for anyone with wider gaps or dental work.

Not all floss is the same. Here's a quick look at the most common dental floss types and how they compare:

  • Unwaxed floss is a thin nylon thread. It can squeak against teeth, but it often frays or catches in tight spaces.
  • Waxed floss adds a coating that helps it slide more easily. Many waxed flosses are still thin, smooth strings.
  • PTFE or "tape" floss is flat and very slick. PTFE is a type of PFAS, a group of chemicals many people now prefer to avoid.
  • Floss picks are convenient, but they're single-use plastic, and the short strand gets reused across your whole mouth.
  • Expanding floss, like NOBS, combines a textured thread with a gentle wax coating. It slides in easily, then expands to grip debris.

Why NOBS Is the Best Dental Floss for Your Routine

The best dental floss is the one you'll actually use every day. We built NOBS to make that easy.

Our textured, expanding dental floss thread does more of the work for you. It grips food and debris, lifts it out and leaves your mouth feeling fresh with a hint of eucalyptus. Customers often tell us it's the first floss that made them feel like they'd just left a dental cleaning.

NOBS also cuts down on plastic waste. Instead of a disposable plastic dispenser, your dental floss for teeth comes in a glass jar you keep on the counter. When you run out, order a refill and drop it into the same jar. Our floss is cruelty-free and never tested on animals.

Floss works best as part of a complete routine. Start with NOBS floss to clear between your teeth. Then brush with NOBS Toothpaste Tablets, which contain 5% nano-hydroxyapatite to support enamel remineralization. Finish with NOBS Herbal Mouthwash, an alcohol-free rinse, for lasting freshness. When the spaces between your teeth are clear, everything that comes after can reach more of each tooth.

Why Flossing Belongs in Your Daily Routine

Your toothbrush is great at cleaning the front, back and chewing surfaces of your teeth. The tight spaces between them are much harder to reach. Bristles can't fully get into those gaps, so food particles and plaque can settle there and stay put. A good dental floss is made for exactly those surfaces, and it reaches where brushing alone falls short.

Flossing doesn't just make your mouth feel cleaner. Clearing out debris between your teeth also helps your breath stay fresh longer, since leftover food is one of the most common sources of odor. It helps the rest of your routine too. With the spaces between your teeth cleared first, your toothpaste can reach more of each tooth when you brush. With NOBS Toothpaste Tablets, that means the 5% nano-hydroxyapatite can reach more of each tooth to support enamel remineralization.

The hardest part of flossing is usually just sticking with it. If your old flossing string shredded, slipped or felt like it wasn't picking anything up, it's easy to see why the habit didn't last. NOBS floss for teeth is built to change that. The textured thread glides in easily, expands to grab more debris and leaves a fresh eucalyptus finish. It takes about a minute a day and makes the rest of your routine more effective.

Frequently Asked Questions About NOBS Dental Floss

Flossing doesn't need to be complicated, but it does need to be done right. Here's everything you need to know about NOBS dental floss and how to get the most out of every pass.

How do I use NOBS dental floss?

Wrap about 18 inches of floss around your middle fingers, leaving 1 to 2 inches taut between them. Guide it between your teeth with a gentle back-and-forth motion. Curve it into a "C" shape around each tooth and slide it just below the gumline. Use a clean section for each space.

How often should I floss?

Floss once a day. Many people find it easiest to make it part of their nighttime routine.

Should I floss before or after brushing?

Floss before brushing. Clearing the spaces between your teeth first means your toothpaste can reach more surfaces when you brush.

What makes expanding floss different from regular floss?

Regular floss stays the same thin shape. NOBS floss expands on contact with saliva, so its textured threads cover more surface area and grab more debris.

What is NOBS dental floss thread made of?

NOBS floss is made from recycled polyester coated with beeswax and vegetable wax, and infused with eucalyptus oil and nigella sativa.

Is NOBS floss PFAS-free?

Yes. NOBS floss is PFAS-free, PFOS-free and BPA-free.

Does NOBS floss have a flavor?

It has a natural eucalyptus aroma that leaves your mouth feeling fresh.

Is the floss good for tight teeth?

Yes. The wax coating helps the floss glide into tight spaces, and it expands once it's in place to grip debris.

Can I use NOBS floss with braces or dental work?

Yes, NOBS floss can be used around dental work. Take extra care around brackets and wires, and ask your dentist about the best flossing technique for your braces.

My gums feel tender when I start flossing. Is that normal?

Some people notice tenderness when they first start flossing regularly or switch to a more textured floss. Be gentle, and if discomfort continues, check in with your dentist.
