Did i pull out a grown up tooth?

so a year ago i went to the orthodontist and i was hoping to get braces, but the they said i need to take out a lot of baby teeth before i get braces. so i took out all of them. the last one was this small tooth i had on my upper teeth and it was loose so i assumed it was a baby tooth that needed to be taken out. yesterday i was wiggling it and it came out. i cleaned up the blood and i realized there wasn't a ingrown tooth there. nothing, only my gums! i was crying because i remember one day i hit my tooth against a seat and it probably loosened a grown up teeth. it was probably a grown up tooth that was loosened because of that reason. what do you think? i hope i didn't end up toothless ):
