Don't stress Sammi! We see this thing often! If it's not bothering him too much, just get him to keep wiggling it until it comes out on it's own. If it's very sore, or hangs in there for a long time, then head off to the dentist, they'll be able to remove it very easily.

As for spaces, don't forget that the teeth coming through are the teeth your kids need to have for the rest of their lives. Their jaws won't always be this small, in fact will keep growing and maturing until they're about 21! So while the teeth look huge now, by the time they are adults *hopefully* all the teeth will fit in. Of course, this is not always the case, and yes Sammi, it can be genetic, so maybe you should start saving LOL.
