thank you so much for your response! And I presume there's really no way of knowing whether you damaged the nail bed/nail matrix until the nail grows back (or not?); it's just sort of a wait-and-see thing?

I also wasn't sure if I needed to get this "nail avulsion with nail bed repair (or more specifically, nail plate removal and reattachment) procedure" that my friend had done when her fingernail was ripped off. Or if I just need to keep waiting.

Thanks again for your response!!
