works without killing enamel -

i can never do professional whitening anything due to the hideous sensitivity it causes. i mean, smiling is painful! so got this at a store with a good return policy: Used it for 5 days straight as instructed, and yes, it worked. i went 1 extra day (10days max recomm) but i reached my Genetic white max at day 4 or 5. i won't ever get paper white teeth like some celeb veneers or enviable friends born with it. BUT, i'm happy with this. Using it takes some diligence, and i gave up squeezing the gel. bad design. i cut it up wide open and used a small lipstick brush to apply the gel. Maintenance is one day a month, so i will have to see if it will hold up in time. i DID feel some sensitivity to cold drinks, but no pain. just a heightened awareness. that in itself is AMAZING.
