The orthodontist first removes piece of jaw bone to reveal the cyst under it. The cyst is then punctured and pus squeezed out. Oozing pus is collected with suction hose. The membrane of the mandibular cyst is then carefully detached from the cavity in which it formed and pulled out through the hole left after removal of tooth. The teeth of the patient suggested that he/she may need to consider visits to the dentist more often and rediscover tooth brush.
