The 4 Best Dental Flosses of 2025

Flossing is a cornerstone of oral hygiene, helping to remove plaque and food particles from between teeth where your toothbrush can’t reach. According to dentists, consistent daily flossing can reduce the risk of gum disease, cavities, and bad breath. 13 With so many options on the market—from traditional string to eco-friendly silk and convenient picks—choosing the right one can feel overwhelming. For this guide, we reviewed expert recommendations from dentists and trusted sources like NBC Select, The Strategist, and Consumer Reports, focusing on factors like effectiveness in plaque removal, ease of use, shred resistance, flavor variety, and avoidance of harmful chemicals like PFAS. Our top picks for 2025 prioritize dentist approvals, user feedback, and sustainability without sacrificing performance.

How We Selected These Flosses

We prioritized flosses with the American Dental Association (ADA) Seal of Acceptance where possible, strong performance in tight spaces, and minimal environmental impact. Dentists emphasize that the “best” floss is one you’ll use daily, so we included a mix of waxed, unwaxed, and natural options to suit different needs, from braces to sensitive gums. All selections are PFAS-free to align with health-conscious recommendations.

1. Cocolab Woven Dental Floss – Best Overall

Cocolab (formerly Cocofloss) stands out as the top pick for its innovative design that makes flossing feel less like a chore. This woven floss is made from recycled polyester filaments coated in vegan wax and coconut oil, creating a textured surface that expands to grab debris while contracting to navigate tight spots. Available in fun flavors like mint, passion fruit, and confetti cake, it comes in a refillable glass dispenser to reduce waste.

Pros: Excellent plaque removal without irritating gums; antimicrobial coconut oil soothes tissues; eco-friendly refills last up to three months.
Cons: Slightly thicker than standard floss, which might require a short adjustment period for very crowded teeth.
Dentists rave about it for consistent use—Dr. Sharon Huang calls it “super-effective” at plaque removal. Ideal for anyone committed to daily flossing with a sustainable twist.

2. Oral-B Glide – Best for Tight Spaces

For those with closely spaced teeth, Oral-B Glide is a dentist favorite thanks to its silky, PTFE-based formula that slides effortlessly without shredding. Lightly waxed and micro-textured for better grip on plaque, it’s available in mint or unflavored varieties and holds the ADA Seal.

Pros: Glides up to 50% easier than regular floss; affordable and widely available; sturdy for braces or restorations.
Cons: May not grip as aggressively as unwaxed options, potentially leaving minimal residue in very wide gaps.
Dr. Rashmi Ambewadikar recommends it for its reliability in tight contacts, a staple since dental school. It’s the go-to for quick, frustration-free sessions.

3. Reach Waxed Dental Floss – Best Budget Classic

Reach offers a no-fuss, minty-fresh experience in a wider “dental tape” format, making it perfect for beginners or those with larger tooth gaps. Made from shred-resistant nylon with a light wax coating, it’s PFAS-free and bursts with flavor to encourage regular use.

Pros: Covers more surface area for efficient cleaning; smooth glide without fraying; super affordable for stocking up.
Cons: The wider design can feel bulky in extremely tight spaces compared to thinner strings.
Endorsed by Dr. Edmond Hewlett for its effectiveness in broader areas, Reach is a timeless choice that prioritizes accessibility.

4. Tom’s of Maine Naturally Waxed Antiplaque Flat Dental Floss – Best Natural Option

If you prefer clean ingredients, Tom’s of Maine delivers with a flat, nylon-based floss coated in natural waxes like carnauba and jojoba, plus spearmint for a gentle clean. It’s free from artificial additives and targets plaque buildup effectively, earning the ADA Seal.

Pros: Gentle on sensitive gums; durable and fray-resistant; appeals to eco-conscious users with plant-derived formula.
Cons: Natural waxes may feel less slippery than synthetic ones initially.
Dr. Ramez Saba praises waxed floss like this for lubricating tight spaces without irritation. Great for those avoiding chemicals while maintaining oral health.

Final Thoughts

The right dental floss boils down to your teeth’s layout, flavor preferences, and lifestyle—whether it’s Cocolab’s fun sustainability or Oral-B’s effortless glide. Aim to floss once a day for two minutes, wrapping it in a C-shape around each tooth. Consult your dentist for personalized advice, especially if you have braces or gum issues.
