Retained Deciduous Teeth!?

Even though I'm already 9 months old, I still have one baby tooth left mew...?

When I ask everyone else, they say all their teeth have changed over by around six months old mew!

I'm worried about it, so I'll look it up mew!

Hmm, let's see...? So this thing called "retained deciduous teeth" can cause problems like a bad bite or even gingivitis mew...?

And if it still doesn't fall out on its own... depending on the situation mew...?

Tooth extraction under general anesthesia mew!?!? :(((;゜;Д゜;)):

N-noooo waaay meeeeewwww!!!
