Dental Floss

Dental Floss for Interdental Cleaning, Expanding Floss and Refillable Systems

Dental floss is designed to clean the tight spaces between teeth that a toothbrush does not directly reach. Everyday floss comes in several constructions, including traditional smooth strands, woven or expanding floss, refillable dispensers, replacement floss spools, waxed options, and specialty formulas.

Expanding dental floss widens during use to increase the amount of material contacting the sides of the teeth. Refillable floss systems separate the reusable dispenser from the replacement strand, which can reduce the amount of packaging discarded each time the floss runs out. Some specialty products also use features such as vegan waxes, essential-oil flavoring, PFAS-free materials, or nano hydroxyapatite; exact materials and ingredient claims vary by brand.

How to Compare Dental Floss

• Standard vs. Expanding Floss – choose between a slimmer strand and a woven floss that broadens during use.
• Waxed vs. Specialty Coatings – coatings can affect glide, texture, and flavor between teeth.
• Refillable Dispensers – reusable cases pair with replacement floss rather than requiring a new dispenser each time.
• Minted or Unflavored – flavor can make flossing feel fresher without changing the basic purpose of the product.
• Nano Hydroxyapatite Floss – some premium floss adds nHA to extend a hydroxyapatite-focused routine into interdental cleaning.

Dental floss works alongside toothpaste and toothbrushes, with mouthwash and tongue cleaning available as additional steps.
