When I was a teenager I had ingrown toe nails... I tried some of the rememdies suggested here... problem is that feet are coated in bacteria.... I eventually got an infection (red itchy streaks) running up my foot and into my calf.
I went to a pediatrist. He cleaned/ and sanatized the areas & numbed me up, took some clippers that looked a lot like little sharp 'dikes' and cut me to the quick, yanked the edge of the nail out that was the offender, then took a q-tip with some sort of acid on it and stuck it in the wound to kill the root.... a perscription of anti-biotics and I was set.
no more ingrown toe nails.
I do get these little slivers that grow where he 'killed' he root (I know I've just got some tough nails
, but they are easy to maintain and never ingrow unless I don't keep them trimmed right and pushed out of my skin.
My toes ached for a few days, and I couldn't swim for a few weeks, but it was worth it as I rarely have trouble 15+ years later.
I'd recommend a pediatrist for anyone with serious ingrown nails.

ETA:
www.epodiatry.com/ingrown_nails.htm Seems to have some good info. I have very curved nails.
FYI the site above says that cutting the v notch in the toe is bunk....
