IF YOU ARE ALLERGIC TO FLUORIDES OR PRONE TO CANDIDA BACTERIA DO NOT USE

I really wanted to give this product a glowing review, but I have to settle on three stars, and here’s why. I decided to try the Ultra Dex product last week after coming across a ton of positive reviews online, which usually guides my purchasing decisions.

In just under three days, I unfortunately experienced a skin rash and soreness in my mouth, only to discover that I'm allergic to fluoride. It’s a bummer, as I noticed a noticeable difference in teeth whitening during that short time! So, if you’re not allergic to fluoride, it seems to really deliver on its whitening promises. But sadly, it just wasn’t the right fit for me.
