Honestly I have used other teeth whitening systems and my gums always seemed to hurt after or I didn’t notice a difference at all . My friend recommended this kit and I just had to try it . After just two weeks my teeth were 3 shades whiter and a yellow stain I had on my front tooth was almost gone !! I will deff order again
Have used it for the past couple of days and have noticed my teeth have brightened at least 2 shades. Looking forward to seeing how my teeth are looking after a couple of weeks of use. Will be buying this product again.
