Bests & Worsts Reviews from Amazon

I don't understand the 'fake' comments. Just because it burned your gums? That's not the sole factor that could make it fake, Karen... I've used this a few times over the past couple years and haven't had problems. I also don't liberally use it each time. I follow directions and just put a drop of it at the base of each tooth's tray molding, and sometimes a bigger drop for my front teeth, cuz they're huge. Then you put the tray on, tap it a bit on each tooth so it spreads, and you're done for now. When you use an excess amount, the gel reaches the gums and burns them. I personally wipe away any excess that pops out of the tray and onto my gums with a finger or cotton swab. I've had good results with these! Also it'd be weird if it was fake because my dentist literally told me he buys it from here, and that's the only way I know about it.
