Four stars out of five , because this is a fantastic product! The missing star is simply personal preference, not quality or ease or anything else under your control.

Your silk floss slides smoothly between teeth, similarly to Glide, made by a huge competitor that's been around for decades and makes everything of plastic. Many people love that product, because it makes life easier for them. But I spent twenty one years in the dental field, and am very picky about function.

Floss should gently scrape the tooth to fully clean under the sulcas (without damaging it or its attachment to the bone in any way), up the neck, and through the contact. Glide simply slides over everything, due to PTFE (the slippery fluoropolymer used in their flosses). I have personally found it useless.

Your silk floss does much better than Glide, but not as good a job as your bamboo floss, and especially not as good as POH unwaxed floss. POH is free of PTFE (the slippery fluoropolymer used in "glide" flosses) and free of PFAS. Unfortunately POH is comprised entirely of nylon. But those who love Glide will love your silk floss even more!

Thanks,
