Did you know your tongue is the fastest healing part of your body?! :)
This is due to the rich supply of blood the tongue receives, making it able to heal twice as fast as any other sections of the body.
All of the nutrients and molecules needed to repair cuts and wounds are in the bloodstream. Tongue has a LOT of blood vessels in it – far more than in the skin. This means that more of the repair factors are delivered to cuts on the tongue faster than they would be delivered to cuts on, say, an arm. If more of the repair factors are there, the cut will be healed faster.
