MacBook lid not flush with bottom case

So I bought a refurb nvidia White MacBook a couple weeks ago and one of the problems I have noticed is that the screen is not flush with the bottom case when closed. The problem is worse on the right side than the left (near the indicator light).

I know that with refurbs you risk getting a slightly less than perfect computer. However, I don't want this problem to get worse. When I first got it I didn't really care but now I'm thinking of the future and of the "what if it gets worse" scenario where I take it in and they think I physically damaged it by accident.

Do you guys think its worth taking it in to get checked out or should I just deal with it?
