This technique is used to teeth following aponeurosis (dead one) that have been blackened.
inside these teeth, after removing the blockage materials (i.e. synthetic resin - gutta percha from the mole of the tooth) we place a special whitening gel (peroxide of hydrogen 35%), which releases oxygen radicals, for a few days. It requires 2-4 visits and the treatment is painless.
