Feel the Burn....
Wicked strong!....If you can handle the discomfort your teeth will come out much whiter after the fist and second use. DO NOT use too much, It will really hurt your gums. I made the mistake of thinking &#34;if this amount is good then twice as much should be twice and good&#34;------WRONG! But if done right there is very little discomfort.
