In answer to your question......We have utilized H202 in concentrations beyond 16%----for whitening effects on teeth....with minor, but sometimes irritating effects. In at least 80% of the volunteers utilizing 16% H202-----tissue-burn was evident by the whitened skin surfaces (even though only the outer tissue level was involved). In a majority of these cases some discomfort did manifest....but no scarring evolved. At 12% the local "heating effect" was
noticed by ALL participants, but presented as a distinct irritation in only about 20% of these researchers. At 9% none of our volunteers experienced any "distinctive discomfort", whatever, but the sudden onset warming, momentarily, caused some of them concern. Everyone using 6% achieved excellent results and at much higher speed....than at 3.5%----but I wanted to err on the side of caution.....that is why I limited my recommendation to the lower concentration. Besides, 3.5% is very easily obtained from any drug store in the U.S....higher concentrations are not nearly as easy to find at the more convenient retail outlets.
I might add an explanatory comment that could prove useful....SOMETIMES, among a population of persons presenting with various stages of gum insults---using even 3.5% concentration----(many are not even aware of such conditions), do experience some rapid-onset stinging discomfort (usually quite short-lived).
This condition evolves as a result of the accelerating effects of the oxygen's heat-releasing effects upon encountering an anaerobic debris-field, or low-grade infectious insults. It is nothing to cause major concern, but is, many times, quite unexpected.
If one does choose to employ 9% strength H202, it would be advisable to have a glass of plain water handy----for dilution, just in case they desire rapid quenching of the oxidation reaction occurring within a pronounced anaerobic tissue field----or even a very tender area. If one does, actually, incur the "bleaching effect" (actually, the white-appearing tissue is a minor tissue-burn and will require a day or two before it sloughs off and is replaced by new tissue), it is, as a matter-of-course, usually self-correcting.
I apologize for such a lengthy response...but few individuals among the general population appear to possess an adequate knowledge of the properties/effects of H202....especially at strengths beyond 3.5%.
I hope these comments prove helpful. Sincerely, Brooks.

Hi Brookes. I am trying your formula of H202 plus DMSO for teeth whitening. The only thing is, over here in the UK the only H202 we can get over the counter is 9%. Would I need to dilute this before adding the DMSO? Many thanks in advance. Dee
