Oh, that's the thing! I knew there'd be a catch somewhere. I couldn't stay away from coffee for whiter teeth. Whenever I feel the need to whiten my teeth, I use hydrogen peroxide with salt and give them a nice brush.
I have used them quite a few times. They definitely work very well, at least for me anyway. But as I reduce my spending and budget, it was one of the first items I had to stop purchasing. I do also worry about how good it is for your oral health overall. But there are cheaper more natural alternatives. I just read Dr. Oz say to put a little lemon juice and baking soda on your teeth..for less than a minute because longer than that isn't healthy for your teeth..and then just brush it off your teeth. I've also read foods like apples and strawberries also have whitening qualities.
