i had my big toe done three times (twice on the right and once on the left side) and the last time i asked if they could do something different. so they said they could put the chemical to kill the root. well i continued to have to watch how my nail was growing out and would pull off the piece of nail that grew back. finally now after 2 years i don't have to worry about it...but my nail sure looks ugly because they had to cut on both sides. also my sister had it done once and the chemical worked for her. so maybe it works different depending on the person.Aim said:They go in and do the regular procedure, but then they use some chemical to kill the root of the toenail. It won't grow back, apparently. So you lose a small sliver of your toenail, but the good part is you won't get ingrown toenails anymore. I had it done on my other toe when I was in University and have never had a problem with it since.
