Possible tooth coming

Tonight I was checking Leilands mouth for any tooth progress, still no teeth. BUT I noticed his bottom right (when looking at him) was just a tad whiter then usual. So I was touching it, and the gums are just slightly raised/ swollen compared to the surrounding. Not sure how long till one may come through, but holy cow we could be signing out of the toothless smile club pretty soon. Tim felt and didn't feel it though. I'm not imagining it though.
