This is one of the best flosses I’ve used. I love the sustainability of the box and the quality of the floss.
Black Reveals Plaque
Non-Toxic
Zero Waste
Vegan and Cruelty Free
Multi award-winning, plastic-free floss with activated charcoal, coconut oil and fresh peppermint.
Clean where your toothbrush can’t reach. Brilliant Black® is a vegan bamboo-fiber dental floss infused with activated charcoal and coconut oil and finished with natural peppermint for a fresh, clean feel. It glides easily between teeth to remove plaque and food buildup, and its black color lets you see the plaque you remove, so every floss counts.
The box is made from FSC-certified recycled paper and is 100% recyclable. Just remove the small metal floss cutter before recycling. Stock up and save with the 3-pack or 6-pack family bundle.
Does Brilliant Black® dental floss whiten teeth?
It helps brighten the areas between teeth. Activated charcoal binds to plaque and surface stains that a toothbrush misses. It doesn’t bleach enamel, but daily use keeps those hard-to-reach spots cleaner and brighter-looking.
Why is the floss black?
Black floss makes plaque and food debris easy to see, so you know exactly what you’ve removed and which spots need more attention.
Is it gentle on sensitive gums?
Yes. Plant-based candelilla wax gives a smooth glide and coconut oil adds a soft, conditioning feel, so it’s comfortable for sensitive gums and tight spaces.
What makes it different from regular floss?
Most conventional floss is made from nylon or PTFE (a PFAS plastic). Brilliant Black® is made from bamboo fiber, infused with charcoal, coconut oil and mint, colored black so you can see what you remove, and packed in plastic-free recyclable paper.
Is it safe with crowns, veneers or other dental work?
It’s designed for gentle daily use and is suitable for most people with crowns, veneers and other restorations. Check with your dentist for personal guidance.
How long does one box last?
Each box holds 32 yards, enough for about 55–60 flosses at 20 inches each, roughly two months of daily use for one person.

I really like this toothpaste from Terra & Co. I have used a lot of other charcoal toothpastes but they make a mess in the sink and this one is not as black as the others so it rinses cleaner. I also liked the taste, not too strong of a mint flavor. My teeth felt clean and my breath felt fresh. I recommend this toothpaste.
Tara F. 5/5 Verified
The taste is fresh and minty, and my teeth feel really smooth and clean after brushing. I like the gentle formula — it’s high quality and not too strong.

I think it whiten my teeth incredibly well. It was a drastic noticeable difference and I didn’t have a terrible taste like other toothpaste that contain the same main active ingredients so I actually really value this.

I am always on the look out for a toothpaste that does not have a lot of chemicals and is not abrasive on my teeth. This brilliant black toothpaste is just that. I love that it can be used on my gums and my teeth. I also love that it comes in a mint flavor and the tube it comes in is simple and modern,

Today I’m using the Brilliant Black toothpaste by Terra & Co. It contains hydroxyapatite and charcoal to help whiten teeth naturally. I love that it’s vegan, non-toxic, and low-abrasive — super gentle on enamel. The mint flavor feels really fresh and clean. I’ve been using it for a few days, and my teeth already look brighter! Plus, it’s TSA approved, so I can take it when I travel. Definitely a great eco-friendly alternative to regular toothpaste!

This feels like luxury oral care. The Brilliant Black Toothpaste has an elegant design and delivers real results, my teeth look visibly brighter and feel smooth, and STRONG. I love that it’s vegan, sustainable, and beautifully formulated!

I absolutely love this toothpaste! It whitens my teeth gently without causing any sensitivity, and my mouth feels incredibly clean and fresh after every use. The mint flavor is light but refreshing, and I appreciate that it’s made with hydroxyapatite instead of fluoride. It’s vegan, cruelty-free, and low-abrasive — everything I look for in a clean product. My teeth feel smooth and polished. Definitely I’ll be repurchasing.

Love this dental floss. Love that there is NO plastic. The charcoal string shows everything you’re scraping off … I know that sounds gross, but it makes me and my family floss more. I have the 32 yard cardboard box of the dental floss here at home and it’s amazing so when I ordered some more from the Terra company website, it gave me the image of the paper box with 32 yards. But I did get a different product and expected. I received the single use strings, which is just a tiny amount. Terra company responded to my review and offered a few boxes I hope they correct the image so not to confuse buyers. Thank you!

Brilliant Black® Floss – Whitens Between Teeth Naturally
Store owner replied: Thank you for taking the time to share your feedback. I completely understand how this could feel confusing, and I want to clarify what happened with your order. Our 32-yard Brilliant Black® Dental Floss in the cardboard box is $10. What was selected at checkout was the single-use trial floss packets ($1.50 each), which is why you received the smaller sample-size packets instead of the full-size box. On the product page, the “single-use” option is highlighted, but I can see how the image created a misunderstanding — and we will be double-checking our product images to make this clearer going forward. As a solution, we’d be happy to send you a couple of our full-size 32-yard floss boxes so you can enjoy the product you were originally hoping for. We really value your love for our products and your honest feedback — it helps us improve. Thank you again for being part of our Terra & Co. community.
I love this floss so much. I’ve been using it since 2020, and honestly, I haven’t found anything else like it. I keep coming back to it.
