Although successful, current treatments fail to re-establish healthy pulp tissue in these teeth. But, what if the non-vital tooth could be made vital once again?	Although largely successful, current treatments fail to re-establish healthy pulp tissue in these teeth. But what if the nonvital tooth could be made vital once again?
