I tried everything from "Crest" Triple-Action Whitening mouthwash, and Crest Fresh Mint Extra Whitening protection and I still get the same results. Do these things actually whiten teeth?

I'm an orthodontist so take it from me, it all really depend on which ones you take, 1 session ones that you buy from the dentist definitely work, the ones you buy from the store sorta kinda work. It all depend on the brand you buy, see usually the most expensive store bought ones are the best and when you get those you have to use them continuously until told to stop otherwise they wont work, they have to work over time.
