In order to maintain your teeth whitening results, it is important that you follow up with maintenance treatments. There’s really two products for maintenance. One is the customizable trays, which are made for you. And the second is a bleaching pen, which is really just like a lip gloss, with a little brush at the end, which you can paint over your teeth, really on a weekly basis to maintain the nice bright white smile. A good analogy for keeping or maintaining results would be, for example, like going to the car wash. If you’ve gone to the car wash, you know, you can get some dust in your car immediately thereafter, and you can easily take a rag at home and you can actually wipe the dust clean from the car. Same thing with your smile.
