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.
By Mayo Clinic Staff. Yellow tongue usually occurs as a result of a harmless buildup of dead skin cells on the tiny projections (papillae) on the surface of your tongue. Most commonly this occurs when your papillae become enlarged and bacteria in your mouth produce colored pigments. Also, the longer-than-normal papillae can easily trap cells that have shed, which become stained by tobacco, food or other substances.
