WAIT A MINUTE. The tooth I was talking about DOES get replaced. I somehow got it mixed up with the molars that :don't: get replaced. I thought my premolars were my other molars since I only have one molar on each side of my mouth. o.o
I have another survey question:
How common is it for people to be missing molars? I know it has something to do with genetics but google isn't being especially helpful by linking "24 teeth" with "aliens"...
