Quick Answer. A tongue that has been completely severed does not grow back at all on its own; however, a tongue that has received severe lacerations, if it receives proper treatment, has the ability to recover rapidly. The amount of time recovery takes depends on the extent of the injury.
Well, grow back is a little vague but gum tissue does grow for different reasons. But if by grow back you mean following recession of the gum tissue away from the neck of the tooth the answer is no. In that case it can be restored by a surgical process called grafting. Gum tissue does become enlarged or swollen due to inflammation (gingivitis).
