针对敏感牙齿，哪些牙线被评为最佳？

Cocofloss is a dentist-designed woven floss made from many interwoven filaments (500+), coated in coconut oil and microcrystalline wax to glide between teeth and lift plaque; a refillable spool (about 33 yards/30 m) and multiple flavors make it a daily-use, eco-conscious choice. It suits users who want textured, expanding floss that grabs plaque and is made from recycled polyester.

Smart Floss is a stretchy, expanding multifilament polyester floss that cushions gums and expands into interdental spaces to remove more plaque; it's lightly waxed with vegetable and beeswax and sold in an eco-friendlier dispenser. It's promoted for use with tight contacts, wider spaces and braces and is PTFE-free and gluten-free.

Listerine Ultraclean uses micro-groove technology and a single-filament design to stretch, slide between teeth, and grip and remove plaque; it is mint flavored and marketed as shred-resistant. Available in professional refill/spool formats and retail packs, it suits users wanting a floss that slides easily and resists fraying.

Reach Mint Waxed Dental Floss is a waxed, mint-flavored nylon floss available in consumer and professional sizes (commonly 55 yd and 200 yd). It uses air-entangled multi-filament technology for shred resistance and smooth gliding between teeth. It suits users who want a waxed, mint floss that resists shredding and comes in larger refill rolls for frequent use.
