I took a photo of my Xray to show the adult tooth that I have impacted. I've marked it in the photo. It's just hanging out there. It's very uncommon to still have a baby tooth when you are an adult, but here I am, in braces, waiting to make enough room for this tooth to come down and join the party! Only 1o more months to go! When there is enough room, they will extract the baby tooth and begin pulling that adult tooth down and into place. Right now it is hiding and can only be seen on xrays.
Here's the profile shot, just because it's creepy cool!
