Question:
Since most teeth whitening systems use hydrogen peroxide, wouldn't it
be effective to simple buy some 30% hp, cut it with water down to
say, 10-15% and use it as a rinse, holding it in the mouth for some
set amount of time?
Of course tooth/gum sensitivity would likely result, but that happens
anyway with the gels used in trays, right?
Answer:
It isnt clear hydrogenium.The concentration is important .The best is
10%.Its the rule -- if you are using higher % the result is faster but it
lasts shorter.
The home -used systems could be dangerous becouse of glum.Thats the reson so
the bleaching tray is very important
Try it on your finger first, and if you find a source
let us know who sold it to you,
Try for 60% H2O2
SuperOxol
Do let us know where you purchase 30% H2O2.
That should be interesting.
Why get rushed to the ER? Don't the gels contain 15-20% hydrogen
peroxide (or carbamide peroxide)? And they're left in for hours,
sometimes overnight.
We used to use Super Oxal (35% H2O2) mixed with sodium perborate to do
internal bleaching. Very nasty, corrosive stuff. You shouldn't assume
that because 15% carbamyl peroxide is relatively safe (btw, it is quite
irritating to soft tissues) that 15% hydrogen peroxide is similarly safe.
