Swelling of the submandibular gland as seen from the outside The stone seen in the submandibular duct on the person's right side Signs and symptoms are variable and depend largely upon whether the obstruction of the duct is complete or partial, and how much resultant pressure is created within the gland. The development of infection in the gland also influences the signs and symptoms. * Pain, which is intermittent, and may suddenly get worse before mealtimes, and then slowly get better (partial obstruction). * Swelling of the gland, also usually intermittent, often suddenly appearing or increasing before mealtimes, and then slowly going down (partial obstruction). * Tenderness of the involved gland. * Palpable hard lump, if the stone is located near the end of the duct. If the stone is near the submandibular duct orifice, the lump may be felt under the tongue. * Lack of saliva coming from the duct (total obstruction). * Erythema (redness) of the floor of the mouth (infection). * Pus discharging from the duct (infection). * Cervical lymphadenitis (infection). * Bad breath. Rarely, when stones form in the minor salivary glands, there is usually only slight local swelling in the form of a small nodule and tenderness.
