funnily enough i was looking into this today. i was surprised to find home tooth whitening kits, exactly the same as the dentists charge £500 in the uk for. you get some gumshields and some gel and just wear the gumshields with gel in for 0.5 hours or something per day for 1-2 weeks. the most amazing thing is the price only £8.99 ($16) on
ebay has anyone tried these sort of kits before?
