Edel+White Expanding Floss (25 m) — Swiss Superfloss That Widens With Saliva

Edel+White Expanding Floss is a Swiss-designed, Italian-made mint-waxed floss that stays thin under tension so it can slide through tight contacts, then expands when it meets saliva to fill wider spaces. Use it for everyday contacts, gum recession (“black triangles”), bridges, and implants. Each spool is 25 meters (27.3 yards).

This is one of the few true expanding flosses still sold in the United States. Customers who used the discontinued REACH expanding floss, or who want an alternative to GUM 2030 Expanding Floss or Dr. Tung’s Smart Floss, come back to this spool because it is easy to find here, priced at a single-spool level, and comfortable enough for daily use.

Why this floss is different

• Thin to insert, thick to clean. Keep it taut to slim the fibers. Relax tension after the contact and let saliva wet the floss so the fibers bloom.
• More surface area in open spaces. Expanded fibers fill embrasures that regular string floss skips.
• Soft, spongy feel along the gumline compared with stiff monofilament tape.
• Waxed mint floss for glide and a clean finish.
• Swiss oral-care design from Edel+White, made for variable gap sizes—not just textbook tight contacts.

Manufacturer claim, not a KleenTeeth clinical study: Edel+White states this Expanding Superfloss technology removed up to 70% more plaque than traditional floss in an internal University of Genoa comparison (2004, tested against three common flosses).

Product specifications

Who this floss is for

• People with a mix of tight contacts and wider gaps
• Gum recession and “black triangles” between teeth
• Bridges and implants, once the floss is in the space
• Anyone searching for a REACH expanding-floss replacement
• Daily flossers who want more volume than standard waxed string

Better choice elsewhere on the site: very tight unrestored contacts may still prefer a thin tape on those teeth first. Braces and some pontics are easier with a stiff-end threader floss such as Edel+White Supersoft Bridge and Implant Floss.

How to use Edel+White Expanding Floss

1. Pull about 16–18 inches (40 cm) of floss.
2. Wrap it and keep that segment taut so the fibers stay thin.
3. Ease it through the contact. Do not snap it into the gum.
4. Once past the contact, relax the tension and let saliva wet the fibers.
5. C-shape around the tooth and sweep up and down under the gumline.
6. Advance to a clean section for the next space.

Use once daily with brushing. One 25 m spool typically lasts several weeks of full-mouth use.

How it compares

Frequently asked questions

What is expanding dental floss?

Expanding floss is compressed and waxed on the spool so it can slip through a tight contact. After it meets saliva, the fibers fluff and fill the space. That extra volume helps clean wider gaps and recession triangles that regular string floss misses.

Is Edel+White Expanding Floss good for tight teeth?

Yes for most contacts, because you insert it under tension while it is still thin. If one contact is extremely tight, use a thin tape on that tooth and use this floss on the rest of the mouth.

Does it work for bridges, implants, or black triangles?

Yes. After you slide or thread it into the space, the fluffed fibers fill an open embrasure, a recession triangle, or the area under a pontic better than thin floss. For fixtures that need a stiff leader, use Edel+White bridge and implant floss.

How is this different from GUM Expanding Floss or Dr. Tung’s Smart Floss?

All three expand. Edel+White is Swiss-designed, Italian-made, mint-waxed, and 25 m. GUM 2030 is a nylon expanding floss with more yardage per pack. Dr. Tung’s uses a cardamom flavor and a biodegradable dispenser. KleenTeeth stocks all three so you can match flavor, feel, and dispenser preference.

Does expanding floss shred?

It is softer and more voluminous than PTFE tape, so treat sharp restorations gently and keep the floss taut on insertion. Do not saw aggressively. If a restoration consistently shreds any expanding floss, switch that contact to tape and keep this floss for the open spaces.

How long does 25 meters last?

Daily full-mouth use is typically several weeks. If this becomes the household floss, use the bulk-price break on this page.

Does it have a flavor?

Yes. Refreshing mint, with a light wax coating to help the compressed fibers glide through the contact before they expand.

Make Edel+White Expanding Floss part of the same routine as brushing: once a day, C-shape, sweep, and move to a clean section. In stock at KleenTeeth for immediate shipping.
