I haven't been using anything for a while as I'm 39 weeks pregnant! But looking for something to start using after baby is here. I've tried all sorts, crest whitening strips (the supreme ones, which are pretty good but not really cheap and have to order them online), and lots of different whitening toothpastes. I don't drink coffee, don't smoke (anymore), brush my teeth regularly obviously, but they always have a slight tinge to them.
I've also had my teeth whitened twice before (the laser and gel thing) which was great but felt like you would need it doing probably one a month!
Any ideas? Thanks!
