Dear M.,
I have never heard of laser treatment for toenail fungus, but I do know that tea tree oil can be effective. First, I would try Vick's vapo rub and sleeping in cotton socks. Use a brush on your toenails when you wash them and make sure they are really dry, even using the blow dryer if necessary to make sure. Then apply the Vick's. I heard about this from my mom and I know it's worked. Give it a try.
