If it's the tooth right next to the wisdom, it's the last one in your mouth. The wisdom is still there right?

When my wisdom came out, it pushed the molars forward, and one of them cracked and had to be removed. I think the term is "impacted". I asked the dentist, do I have to start wearing dentures? He opened his mouth and showed me where he is missing a molar as well. No need, he says.

The gap has never bothered me. It's not visible when I smile. I don't even notice it when I eat.
