Are those new teeth whitening strips really safe? How do they work? How frequently can you use them?
The August 2001 issue of my seventeen magazine says
If you’re interesting in whitening your teeth, you should check out this issue from your local library. They also discuss toothpastes, mouthwashes, floss, home bleaching systems, trays, and laser bleaching.
You don’t know how grateful I am that there is a Seventeen magazine reader on the boards.
