I personally don't. The fact that Toothless can't fly on his own is a very important part of his Friendship with Hiccup. Remember Gift of the Night Fury?

Not too mention there is no need for the story to regrow the tail. Infact, if his tail suddendly grew back, I would think it would be very Stupid and unrealistic.
