Okay. So, I've been doing some more floss reading. One article, by a dentist says the best kind of floss is "The one that you will use." In other words, personal preference. If you find one you like, then there's more likelihood that you'd floss and not skip.
I went ahead and bought 2 packs (buy 1 get one 50% off) of the CVS replacement of that one that I loved. Just to try out and see for me thumbs up or thumbs down. Then I tried to buy the Walgreens Hi-Tech Floss but after going to two Walgreens, they were nowhere to be found. With further reading, looks like "Hi Tech" floss is newer floss, that works well for tight teeth and the floss doesn't shred. Plus, a stores besides Walgreens, such as Kroger or Meijer carry their own. The next time I stop by Meijer, I'm gonna have to pick up a pack to try.
Update: Tested out the newer CVS floss which goes by "CVS EaseBetween Original Dental Floss, Fresh Mint". Initially, I thought, this is almost like the old stuff. Feels pretty close, but later noticed, that this does have some shredding whereas the old did not. I'm still searching for a decent replacement
. I'll have to try out that Hi Tech from Meijer.
