Dent in my frame, should I be worried?

I just bought this bike a few months ago and I crashed pretty hard last night. I've dented the frame. It's about 3/4 of on in diameter and less than 1/4 of an inch deep. It's on the bar that links the headset to the bottom bracket.
How concerned shoud I be? I guess I should probably take it to a shop and get them to look at it. There is no crack or anything just a dent. I really don't want this thing to buckle next time I'm out.
The red circle shows where the dent is. I don't have an actual pic of the damage.
