You can't always have the cake and eat it too - but now you can have the coffee and sport a sexy set of pearly whites thanks to GoSMILE. They make these little tooth whitening ampoules that you can use anywhere - just smash it with your fingers until you hear it crack and then the liquid is activated (or something like that) and you just brush it over your teeth - targeting any problem areas that you might have. Forget trying to hide a drippy toothbrush in that hot little handbag - these little viles of tooth goodness are better than anything the tooth fairy ever had to offer.
