These things do happen unfortunately, you need to get them fixed and move on.
I picked up a dent about 2 inches across on the passenger door on my E90 when it was a few months old and I was not happy. Got one of those local smart repair dent people out and did a fantastic job. I couldn't believe how well they fixed it and well worth the £80 or £90 to do it.
Its amazing what they can do these days without having to do major work.
