Flossers with fluoride okay?

So my daughter will be 2.5 in December. We use a non fluoride toothpaste for her as we have it in our water supply.

When I took her to the dentist they gave her a flosser and she loved it, so I went on amazon and bought a big pack.

Now I realize they have fluoride? Do you think this is okay to use since it’s not something that she is swallowing as she would toothpaste? Have any other parents used these who also prefer not to use fluoride, or would you as a parent who doesn’t?

I’m also trying to figure out what they are “artificially flavored” with. What do you guys use to floss your toddlers teeth? 🤔
