I have seen it more than once, a finger that was slammed in a door, drawer or cabinet that really injured a fingernail. The damaged nail is dark, bruised and it feels loose. Is it going to fall off? It could! A badly damaged nail will most likely fall off but probably not for a while because it is usually still partially attached. An injury to a nail such as the nail being caught in a drawer or being slammed in a car door, that causes bruising to the nail bed, and can break the nail plate. The nail is broken but is still attached to the nail bed. There will be new nail growing in pushing the loose injured nail out. The damaged, broken nail will become looser and looser as more new nail grow in. Help My Nail if Falling Off! There are some things you can do to help keep the nail on for as long as possibly while the new nail is growing in. That loose nail is still protecting the sensitive nail bed.
