10 Best Dental Floss Brands 2025 in the United States

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.

The DenTek Triple Clean Advanced Clean Floss Picks are designed to provide a thorough clean with their unique features. The floss picks use DenTek's thinnest and strongest floss, which is made up of over 200 individual cleaning strands. This ensures that the floss does not break or shred during use, making it highly reliable. The micro-textured pick is particularly useful for scraping away stubborn bits of food and plaque, enhancing oral hygiene.

Additionally, the floss is flavored with a mouthwash blast and infused with fluoride, which can leave your mouth feeling fresh and help prevent cavities. These floss picks come in a mint flavor, which most users find pleasant and refreshing. The product comes in a convenient stick form, and includes 20 counts in each of the 6 packs, making it a cost-effective choice for regular use.

However, while the strength and reliability of the floss are commendable, the environmental impact of the plastic picks could be a concern for environmentally conscious users. The product does not appear to offer any eco-friendly or biodegradable options, which might be a drawback for those looking to reduce their environmental footprint. Additionally, the thickness of the floss may not be suitable for individuals with very tight dental spacing as it could still be too thick despite being the thinnest offered by DenTek. Despite these potential drawbacks, the ease of use and effectiveness of the DenTek Triple Clean Advanced Clean Floss Picks make them a strong contender for those seeking a reliable and efficient dental floss solution.

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.
