10 Best Dental Floss Brands 2025 in the United States

DrTung's Vegan Activated Charcoal Floss is a natural, plant-based floss designed to gently clean between teeth. It uses an expanding, stretchy material that helps reach tight spaces more effectively than some regular flosses. The activated charcoal coating aims to enhance plaque removal and freshen breath. This floss is free from common chemicals like BPA, PTFE, and PFAS, making it a good choice for those concerned about allergens and environmental impact.

It is marketed as gentle on gums, with a cushion-soft texture that can reduce discomfort during flossing. The lemongrass flavor adds a fresh, pleasant touch. Being a plastic-based product, it is not fully biodegradable, which may be a consideration for environmentally conscious users. The expanding nature of the floss may require some adjustment for those accustomed to traditional floss.

The floss features a medium thickness suitable for most adults. It is ideal for anyone seeking a natural, chemical-free option that is gentle on sensitive gums and effective at cleaning hard-to-reach areas.

DrTung's Smart Floss is a natural, expanding dental floss designed to stretch and widen as you use it, helping to clean hard-to-reach areas more effectively—up to 55% better than some other flosses. Made without PTFE, PFAS, BPA, or petrochemical wax, it appeals to users looking for a floss with a cleaner, more environmentally friendly formulation. The cardamom flavor offers a unique and refreshing alternative to common mint flavors, which might be enjoyable if you prefer something different and natural. The floss is soft and gentle on gums, providing a cushioning effect that reduces discomfort, making it a good choice for those with sensitive gums or who find regular floss harsh to use. Its strength allows it to handle tight spaces without breaking, which adds to its ease of use.

One consideration is that expanding floss can feel a bit different from regular floss, so some users might need time to get used to the stretchiness. Also, while the natural materials are a plus, the product packaging is relatively large and heavier than typical floss packs, which might not be ideal if you want something very compact for travel. This floss is well suited for people who want a gentle, effective, and natural option that also pays attention to environmental concerns, especially if you appreciate a unique flavor and softer floss experience.

Cocofloss Woven Dental Floss stands out in its category with a distinctive design by a dentist, which addresses common complaints about traditional floss types. It is woven with 500+ interwoven threads that expand, effectively reaching and capturing plaque, which can help in maintaining a bright and clean smile. This feature may be particularly beneficial for individuals who find traditional floss to be less effective in cleaning. Additionally, the floss is waxed and infused with coconut oil, offering a smooth glide between teeth which could make it more comfortable for those with sensitive gums or teeth.

The product is also eco-friendly, being made from approximately 85% recycled water bottles, which may appeal to environmentally conscious users. Its refillable dispenser further reduces waste compared to single-use plastic flossers. Furthermore, it is vegan and cruelty-free, aligning with ethical consumer preferences.

In terms of thickness, the expanding nature of the floss could be an advantage, although some users might find it thicker than standard floss, which could be a downside if their teeth are tightly spaced. However, the textured, net-like structure may provide a superior clean for those not satisfied with flat, tape-like flosses. Ease of use is highlighted by its kid-friendliness, suggesting that the floss is accessible even for younger users. The mint flavor adds a refreshing touch, contributing to a pleasant flossing experience.

A potential drawback could be the cost, as dental floss with such specialized features might be priced higher than standard options. However, for those who value eco-friendliness, comfort, and effective cleaning, Cocofloss presents a compelling choice. The company's promise of customer satisfaction with a refund policy further encourages trying the product without risk.
