After years of smoking and coffee it’s been a task trying to whiten my teeth now I don’t smoke anymore, I thought this stuff wasn’t working then I remembered I took a picture of just before I started using it,I suggest everyone do the same as it happens gradually and you can see the difference,I have been using this twice a day for nearly 3 weeks now and you can see the difference,To get the best results I have dried my teeth and gums before applying then using the pen then letting that dry on my teeth before I close my mouth properly,I also don’t drink afterwards for a while as this can make it wash off and all this seems to be working.I was skeptical buying this but I took the chance and glad I did as its doesn’t cost the earth like other products to whiten the teeth.Also worth mentioning I have very sensitive teeth and use sensitive toothpaste and this pen has not made them any worse and seems safe for me.

Right…. So my teeth are awful! Very very stained. Bad genetics and a love of black coffee. Dental cleaning and brightening kits don’t do much . I’m thinking about veneers. Thought I’d give this a go. Above is the picture after 1 st application. It made a massive noticeable difference immediately to the extent that I won’t use it again because it’s probably dangerous! Honestly. Steer clear. I’ve rinsed my mouth out and wiped it all off, but honestly. I think it might just be bleach!
