I tried this on a whim as my hygenist cost is very pricey and now I no longer have to go. I wish I'd taken a before picture of the back of my lower teeth. They we're a light brown colour, as were my fixed retainters, and now they're almost 100% clean, there are a few parts I couldn't reach because it's a little tricky to use, but I'm fairly confident I'll be able to remove more as I become more experienced. This thing is basically the same as what the dentist uses, but doesn't have the flow of water to wash away the broken down tartar
