Toddler (20months) hit tooth?

She was running and went face first into a bedpost, and hit her mouth. Once tooth (the one beside the k9) bled a little around the gums, she won't let us touch it though. The tooth itself is very tiny anyway so I am sure it isn't loose (waiting for naptime so I can hopefully check). She ate a popsickle and seems fine now (also gave baby motrin). Any advice? Thanx in advance!
