My two upper front teeth have always been in perfect position until
this year alone. I can't tell which tooth shifted but one tooth is out
a bit and one tooth is in a bit. It's not crooked or anything. It just
shifted forward or backwards. I can feel it with my tongue or when I
run my fingernail across them.

I am now 25 years old. Is this normal? I don't have a lot of money so I
can't exactly rush along to the dentist but I am getting concerned
because if this type of thing doesn't happen, am I facing the
possibility that my teeth may continue to shift?
