Clinic? sometimes there light doesn't work.. my uncle did that and it made his teeth more yellow. I think there is a reason why companies are coming out with the stripes and stuff like that. Personally I think you should go with the Listerine Stripes. They dissolve in your mouth. You can use them anywhere and anytime!
