<unk>  rarely cause any symptoms, unless they become secondarily infected. The signs depend mostly upon the size and location of the<unk>  If the<unk> has not expanded beyond the normal anatomical boundaries of the bone, then there will be no palpable lump outside or inside the mouth. The vast majority of<unk>  expand slowly, and the surrounding bone has time to increase its density around the lesion, which is the body's attempt to isolate the lesion.<unk>  that have expanded beyond the normal anatomic boundaries of a bone are still often covered with a thin layer of new bone. At this stage, there may be a sign termed "eggshell cracking", where the thinned cortical plate cracks when pressure is applied. A lump may be felt, which may feel hard if there is still bone covering the<unk>  or fluctuant if the<unk> has eroded through the bone surrounding it. A<unk> may become acutely infected, and discharge into the oral cavity via a sinus. Adjacent teeth may be loosened, tilted or even moved bodily. Rarely, roots of teeth are resorbed, depending upon the type of<unk>  The inferior alveolar nerve runs through the mandible and supplies sensation to the lower lip and chin. As most<unk>  expand slowly, there will be no altered sensation (anesthesia or paraesthesia), since the inferior alveolar canal is harmlessly enveloped or displaced over time. More aggressive<unk> , or acute infection of any<unk> may cause altered sensation. Sometimes, they cause higher risk of pathological fracture of lower jaw, especially around angle of mandible.
