Revasularization of Immature Teeth:

In certain cases where immature teeth have become necrotic, it may be possible to reestablish the tooth’s blood and nerve supply through a procedure called revascularization.  The necrotic tissue is removed and the tooth is medicated with a paste called calcium hydroxide.  After two weeks of allowing the medicated paste to work, it is removed and bleeding stimulated through the apex of the tooth.  That bleeding brings with it the cells necessary to reestablish the tooth’s blood and nerve supply and allow the tooth to mature and become stronger giving it a better long term prognosis.
