"By the skin of your teeth" is an expression that means you just barely did something, or just barely escaped a bad situation. It's like saying, "I almost didn't make it," or "I just narrowly avoided something bad happening." For example, if you were taking a test and you only got one question right, you could say you passed "by the skin of your teeth." It's a way of expressing that you were very lucky to have succeeded or come out unscathed.
