Great product! Teeth whiter after only 2 days!
Great product!  Didn't hurt my very sensitive teeth.  I actually noticed my teeth were a shade whiter after only 2 days.  Like most people who bought this, my teeth were not exactly glowing white due to daily coffee, age, etc.  I followed the simple instructions and kept the gel on for 20 minutes then simply rinsed with water.  After second use, my girlfriend said, &#34;Wow, order me one too!&#34;
