My ortho has me use a nightly fluoride treatment- Colgate Phos-Flur Gel- and I have run out of it for the first time. She gave me this prescription, but I'm wondering if it's an over-the-counter type of thing. How do you all get your fluoride treatment when it runs out?

I noticed that they sell it at Wal-mart. It is quite expensive though running about $12. Hope this helps
