em ... i was only at my new Dentist last Tues asking about teeth whitening (though she didn't think i needed it but i can't help myself i'm a teeth fanatic, LOL) ... and she said the guards that they need to have make from a mould cost the most about $650 and the tubes of whitener about $40. The guard you wear each night filled with whitening gel for about 7 nights. She mentioned if the whitener doesn't whiten my teeth brighter as it is possible (but rare) she said the next tube of whitener they can especially order in a stronger one She said the whitening can last between 1 to 2 years (depending on if you drink coffee, smoke, etc ...)

Told her i can't afford$$$ it now ... and she said she doesn't know of any chemist one's she can recommend but having said that she did add that a friend of hers (i'm hoping they are a Dentist??) recommended the COLGATE teeth whitener that looks like a nailpolish bottle as she described and you paint it on (keeping in mind she herself doesn't know of it's success BUT that her friend said it worked)
