Powersmile whitens well and tastes great. Cleaning action makes dental checkups easy. One downside is that powersmile contains no fluoride.

Great way to dispense toothpaste. Takes up little more space than a travel size tube in my toiletries bag, and less messy. I like how portable and small it is.

It whitens better than the dental tray for me. Flavor isn't bad, though i prefer a stronger minty flavor. I like the colgate brand and this particular taste is very nice.

The paste is now bright blue, no longer white and the blue stains my teeth and mouth blue. Had to wash the tape residue off with alcohol while wearing rubber gloves. Too runny. Drips off tooth brush. Will not buy it again.
