So my teeth were yellow. And for the longest time I have wanted to get the whitening stuff. But I couldn't afford the $40-$50 dollars for the stupid things. So today I found a great find. Target advanced whitening wraps. You do just 30 minute, twice a day for 7 days. After only one application, I saw a difference...after two I saw even more. And I still have 6 more days to do this! And the best part...it only cost around $14 for 28 strips...(14 top, 14 bottom). So if you wanted do the whitening, but didn't have enough cash, the target brand works just as good.
