Great value/great product
Even though I have my teeth professionally cleaned twice a year, I was noticing they were becoming yellow mostly near the gum line; probably from coffee!<br /><br />I thought I would give this product a try. Wow. My teeth are several shades lighter. The product is easy to use and one pen last a long time.<br />I have ordered twice and will order again!  Thanks.
