Description

POH Percept Micro-Thin 420 Black NoWax Dental Floss is engineered for people who need ultra-thin floss that can reach tight spaces where standard products fail. The micro-thin black nylon thread slides between crowded teeth and narrow contacts, making it easier to dislodge plaque before it hardens on enamel. The distinct black color creates clear visual contrast, so users can actually see plaque and debris as they remove it, reinforcing good habits and the effectiveness of their daily routine.

Each dispenser includes 100 yards of unwaxed, unflavored nylon floss, offering long-term value and supporting twice-a-day use without frequent replacement. The six-strand construction provides a slim, precise feel that still maintains enough texture to grab plaque and food particles along the way. This makes POH Percept 420 a strong choice for hygiene-conscious users, professionals, or anyone seeking greater control over their flossing routine, while still fitting seamlessly into any existing oral care regimen.

Key product features 

  • Micro-thin, no-wax floss slides into tight contacts that standard floss misses, helping remove hidden plaque for a cleaner mouth and fresher breath.

  • Black nylon thread creates strong visual contrast, making plaque and debris easier to see as you floss so customers can instantly gauge how effective their routine is.

  • 100 yards of professional-grade floss per roll offers long-lasting value, reducing reorder frequency and supporting consistent daily oral care.

  • Six-strand fine nylon construction delivers a precise, thread-like feel that glides smoothly between teeth while still gripping plaque along the way.

  • Ideal for crowded or tightly spaced teeth, giving users greater control and accuracy to support healthier gums and more confident smiles over time.

  • Unwaxed and unflavored design keeps the experience clean and simple, pairing easily with any toothpaste, mouthwash, or professional hygiene protocol.

  • Made in the USA

Frequently Asked Questions

What makes this floss "micro-thin"?

POH Percept 420 uses a fine six-strand nylon construction that's thinner than standard floss, letting it slide into tight or crowded contacts where regular floss can shred or get stuck.

Why is the floss black instead of white?

The black nylon creates visual contrast against plaque and food debris, so you can actually see what you're removing as you floss. Many dentists recommend it specifically to help patients confirm they're flossing effectively.

Is black dental floss safe to use?

Yes. The black color comes from the nylon dye used in manufacturing, not a coating or chemical additive, and it's just as safe as white floss. It won't stain teeth or gums.

What's the difference between NoWax and LiteWax versions?

NoWax (this product) has no coating, giving a slightly grippier feel that some people find better at scraping plaque. LiteWax adds a light coating for a smoother glide between tight teeth. Both come in the same micro-thin 420 gauge.

How is 420 different from POH's 630 floss?

420 is the thinnest POH Percept gauge, built for tight or crowded teeth. 630 is a heavier-duty strand for people who want more texture and durability but don't need the extra thinness. Both are available waxed or unwaxed.

How long does one spool last?

Each spool holds 100 yards. Flossing once daily using an 18-inch length, one spool lasts roughly 4-5 months per person.

Is this floss waxed, flavored, or coated?

No. This NoWax version is completely unwaxed and unflavored, so it pairs cleanly with any toothpaste or mouthwash without adding taste or residue.

Where is this floss made?

POH Percept floss is made in the USA by Oral Health Products.

    poh unwaxed floss

    Posted by carla w on 19th Jul 2023

    I tried the black 420 and white 490. Both are good, It's fantastic to find fine unwaxed floss. The black shreds a bit too easily, so I'm going with the white. They're both thin enough for me.

    best replacement floss

    Posted by Monica Bliss on 1st Feb 2019

    My favorite floss was discontinued by OralB. This a very close replacement. Shreds a little more than I like but I do like the black as it shows the plaque.
