Hammy may have torn out a toenail

[Adrienneinohio]

We woke up this morning to find our Dexter had escaped his bin having popped the screen off the top after chewing through zip ties. At any rate, he appears to have passed the evening hours trying to dig out from under the bedroom door. The carpet is gone clear down to the backing. Though we didn't find a toenail, one of his toes is bloody(dried). It's not still bleeding, and I didn't feel anything jagged, so I think the nail is actually torn off at the base. Will it grow back? I'm assuming that since the bleeding stopped, there's not much else to be done. But thought I would check with you all.
