Weldental 木糖醇牙線，膨脹式牙線 50m

Honestly, I was skeptical about "expanding" floss, but this one really does glide into tight spaces without shredding. The fact that it has xylitol is a huge plus since it actually tackles the bacteria instead of just moving them around. For 50 meters, the price is a steal.

The glide between teeth is so smooth, and it grabs onto plaque way better than the flat floss I used to buy. It doesn't fray or snap even in my tight molars, and the 50m spool lasts me ages.

The expanding action really locks onto the surface of each tooth, and the glide is smooth enough that I don't dread flossing anymore. It's held up without fraying even in my tightest molars, and the 50m spool has lasted way longer than my old rolls.
