When the inflammation is too extended and the tooth can not be “saved” through denervation only, the process of apicoectomy is considered as necessary. This is a microsurgical procedure in which the specialized dentist (usually a periodontist or a maxillofacial surgeon) proceeds to reveal the gums and removes a small piece of the root, together with the infected tissue. The edge of the root is hermetically sealed with a special blockage material. After the procedure, sutures are applied to the gum, in order for the wound to heal.
