Ok, so I've been reading about phosphoric acid after I found it on the list of ingredients on a teeth whitening product. Acid? Is that just eating away my teeth?? Isn't that the ingredient in Coke that makes it bad for your teeth? wikipedia says it is sometimes used to whiten teeth, but is it safe? by the way, the product is "5 Minute Speed Whitening Gel" by a company called Plus White (www.pluswhite.com) thanks in advance!
--------------------
phosphoric acid is very bad and it's active indredients on teeth whitening. In office 1 hr whitening such as Zoom or rembrant, etc... it contains approx. 36% or more home whitening contains any where from 12-20% depends on the product. It's not safe if you put 36% on the teeth for long time because it will "eat"away your enamel. Also it will burn your gum instantly. home whitening kit that contains 12-20% will burn your gum if you put it on for 1 minutes or more. That's why you shouldn't use such product on your own without dentist next to you. Why we use them? because concept of whitening is to etch and remove external stains on the enamel. over time, saliva will replenish and mineralize your tooth. If you do it too frequently, your teeth will be sensitive and you will forever damage your teeth. Only way to desensitize is to use stannous flouride (gelkem) prescribed by dentist. But i've seen some of my patients needing Rootcanal treatment due to overexcessive use of whitening product. All those crappy whitening gel when used correctly might give you a happy result once, but it not work several times. It will in other hand damage your teeth if you abuse it.
