I'd get the alignment checked. The only real adjustable angle is toe-in. you won't really notice a difference going down the road now but in a few thousand miles you might see feathering wear on the tread. Incidentally, the same thing happened to me a few years ago. I hopped a curb after taking a short ride on a sheet of ice, slammed into and over a curb, was a rather violent experience. If you damaged a wheel, you most likely knocked the alignment out a tad.
