Grey Tooth - 2 year old

Savannah

My 2 year old has a front tooth turning grey (excuse the dirty face). We are 99% sure it's from him hurting his mouth (he's constantly busting his lip by jumping off things and being crazy in general). He already has an appointment with a dentist.

Have any moms out there gone through this with a kid?? What happened? Feeling panicky that he's going to end up losing it. I already have an older son who's missing front teeth for tooth decay reasons.
