I'll try to keep it short, I won't be too verbose about my history, regimen, etc. If need be, I'll write about them later.
I have never heard of a relationship between dental hygiene or gum health and acne, but simply flossing every night has reduced my lesions by 90%. It hasn't cured me though, my skin is still sensitive, flossing is simply the most important piece in my acne regimen, but if I neglect my diet or sleep poorly (things which by themselves never had any effect on me), my skin will react.
I've already had temporary successes fighting acne 3 or 4 times in past, but inevitably all would return to normal in no longer than 3 weeks. But this time my skin has been almost acne free for 3 months, with the exception 2 one-week periods in which I did not floss, thus confirming my hypothesis.
I would like to ask your help with two things: 1) figuring out a link that explains the relationship between flossing and acne, and 2) devising regimens and strategies to 'complete' my cure taking into account that explanatory link and thus preventing the 10% of remaining acne from breaking out.
