Today I received the Dr. Song Professional Teeth Whitening Kit with 44 % Carbamide free of charge for my honest Review. I first applied the Dr. Song after reading directions and I put a little to much on my teeth so it fizzed but it cleaned around the gums where my teeth needed it. I used a brush to apply the Dr. Song on the bottom teeth. The teeth are whiter and also look a little smoother. You can purchase the Dr. Song on Amazon. Thank you, Jerri Davis
