if you don't like to waste your money at dentist!
they are the best in their category! 1 - easy and gentle whitening, especially for someone who has sensitive teeth 2 - 3 day only and you see amazing results 3 - if you think it can damage your teeth or enamel try use it each 2 day instead of each day 4 - price according to a dentist session super nice just one minus it doesn't make all your teeth white (only visible smile as a stripes short enough)
