When my mom was younger, she had something like that but she just got it pulled. I'm not sure on the details..she needed a root canal or something and ended up getting it pulled but I think there was something else. Anyway, she never had anything to fix it, so now she has a gap there..I'm so panicy about my teeth, I hate em! I have to get my wisdom teeth pulled god knows when and I'm freaky out about it all ready, I'll hate to know when the date is!!! I'll probably pass out. Stupid wisdom teeth..ok off topic, sorry!
