So I’m looking for teeth whitening. My teeth are very white. I use whitening toothpaste and mouthwash everyday, but I want to be whiter. I used the crest strips in the past and was happy with them. But I thought of looking to other systems just for fun. EBay has some really cheap games that claim to be the same as what your dentist might use. Has anyone bought these before and they really? What I see is only $ 15 so it’s not like I’m going to lose but their jobs. Any advice would be great! thanks!
