what is the best teeth whitening product?
--------------------
Hi my friend, My dentist told me $400 for the trays of professional whitener professionally molded to the shape of your teeth. ($200 top, $200 bottom) but if I wait until January, it's discounted to only $300 ($150 top, $150 bottom) My dentist also offers "Zoom" that uses light to whiten, but that costs $800 and does the same thing. Both options my dentist offered are 10x better than the whiten-at-home things, and they are done professionally. PLEASE DO NOT FALL FOR THE WHITEN-AT-HOME SCAMS! You see, for only $300 I can get my teeth professionally whitened, but if I spend $80 like ten times over the course of several years for the ones like Luminous Brites (SCAM), I could have just as easily spent that $800 on the light-whitening thing at the dentist, or I could do the $300 option that is just as good, and used the other $500 on something more important. Also, think about the time you'll have to spend doing it yourself - not to mention most people never even finish one set of them because it's tedious! Also, all the ones you can do yourself like Lumious Brites (SCAM) many people have reported it causing sensitive gums, which is a serious dental issue and could cost you another $1,000 - $3,000 in dentist costs! So just save like $300 and get your dentist to professionally do it for you. Then you have no worries! Also it's just a waste of money to pay for the light-whitening or laser-whitening. The dentist makes a ton of money off it too, so don't let him/her sell you on it! It really works no better than the professional whitening that is placed in a plastic/rubber/ish [professional] impression of your teeth. Also your dentist knows what he's doing and if he screws up you can sue him for malpractice so at least you have a fall-back plan so you don't get screwed up gums and stuck with a $3,000 dental bill. If you screw up your gums yourself, you have no fall-back plan; and plus you're not an expert but your dentist is. Hope this helps! Good luck!
