Is The Flash healing factor ultimate like Wolverine's, or is it limited to a tissue type and/or percentage of damage?

In one of the episodes, Cisco says to Flash "(...) watch out for teeth, because they don't grow back.", which makes me wonder about Flash's healing abilities.

How does it look in the comics as compared to the new TV series?


Barry Allen, in The Flash, doesn't have a healing factor in the sense that the term is typically used in comics. He is not able to heal wounds or injuries that normal humans could not.

What he has is accelerated healing -- because everything about his biology is accelerated, he heals the same way that a non-metahuman would but it happens more quickly. For example, if a person Barry's age were to fracture a bone in their arm or leg, it would typically take about 6 weeks for it to fully heal. If Barry were to fracture a bone in his arm or leg, it might heal in a matter of days or even hours.

However, if Barry's hand were cut off, the bleeding would stop and a stump would grow over the injury very quickly, but he wouldn't regrow a hand the way Wolverine would.

    Idk, the speed force would probably give him a lightning hand or some nonsense. – user16696 May 31 '15 at 3:46

    @cde Nah, more likely, his accelerated healing would just heal the damaged tissue between the hand and his arm, thereby reattaching it. lol – jpmc26 May 31 '15 at 5:08
  • What, like in blade 2? – user16696 May 31 '15 at 5:53
  • Well, in the TV series Flash don't develop a scar tissue and he can survive falling down from several floors, so it's still little more than just an accelerated healing. – oski86 May 31 '15 at 22:32
  • @oski86: it is the kinetic energy (hence the velocity) that hurts during a fall from several floors. So he may be protected by the Speed Force. I remember in the 90's Flash TV show, the Flash was able to catch bullets without any harm, when he was moving fast enough. – Taladris Jun 3 '15 at 16:10
