The Healthiest Way to Floss Your Teeth

Flossing matters because your brush can't reach around a third of each tooth surface. Do it right and you cut plaque, bleeding, and bad breath. Do it badly — or not at all — and you're polishing the easy bits while problems brew in between.

Below is a straight-talk guide: which floss types work, how to floss correctly, and where eco-friendly floss fits without compromising your clean.

Is Dental Floss Good for Teeth?

Yes, when you use it daily with good technique. Floss disrupts plaque between teeth and just under the gumline, where toothbrush bristles don't reach. Expect mild bleeding if you're new to it — that should settle within a week of consistent, gentle flossing. If it doesn't, talk to your dentist.

The Healthiest Way to Floss (Step-by-Step, 90 Seconds)

1. Cut around 45 cm and wind most around one middle finger, the rest around the other.
2. Slide, don't snap. Guide the floss between teeth with a gentle zig-zag motion.
3. C-shape hug. Curve around one tooth, glide up and down from just under the gum to the tip 2 to 3 times, then repeat on the neighbouring tooth.
4. New section, next gap. Move to a clean segment for each space.
5. Once a day, at night. Water flossers and interdental brushes are great add-ons, not full replacements.

Go slow around tight contacts. Gentle pressure wins. If dexterity is an issue, use a floss holder.

What Type of Dental Floss Is Most Effective?

The one you'll use every day without shredding or pain. Materials change feel and friction — helpful for different teeth.

• Nylon (waxed/unwaxed): reliable all-rounder; textured feel can grab plaque. Not biodegradable.
• PTFE (glide style): ultra-smooth for very tight contacts; rarely shreds. Not biodegradable and PFAS-based — many eco-minded users avoid it.
• Silk: plastic-free and biodegradable; soft on gums. Can fray if forced through tight gaps. Not vegan.
• Corn-based (PLA): plant-based and compostable under the right conditions; smooth feel. Can snap if you yank — use a patient zig-zag entry.
• Bamboo charcoal fibre: strong, slightly grippy, and the black colour shows what you removed. Good balance of strength and scrub. See our full dental floss types guide for a deeper breakdown.

How to choose:

• Tight contacts or fillings that snag: smoother floss (PTFE-feel or a smooth eco alternative).
• Normal or wider spaces and you want more scrub: textured options like silk, woven nylon, or bamboo charcoal.
• Sustainability a priority: silk, corn-based PLA, or bamboo charcoal.

Our Eco Floss range is designed for performance and planet.

Corn-Based Eco Dental Floss — plant-based comfort

How to dispose (honest version):

• Don't flush floss — it tangles plumbing and harms wildlife.

Flossing FAQs

How often should I floss?
Once daily. Nighttime helps remove the day's plaque before you sleep.

Should I floss before or after brushing?
Either — just do both. Many people prefer floss first, then brush and spit (delay a big rinse so fluoride can work). Read more in our guide on whether to floss before or after brushing.

My gums bleed when I floss — is that normal?
A little at first, yes. It should improve within around a week of daily, gentle flossing. Persistent bleeding means check with your dentist.

Are floss picks okay?
Better than nothing, but string floss wraps the tooth in a C-shape for a deeper clean. Picks are great on the go; at home, use string or add interdental brushes.

Water flosser vs floss?
Water flossers are excellent add-ons, especially for braces and implants, but they don't replace string floss in tight contacts.

Best floss for sensitive gums?
Soft, smooth options like corn-based PLA or well-waxed silk. Go slow and never snap. If soreness persists, speak to your dentist.
