Untreated root cysts may lead to a series of serious consequences, such as loose teeth, alveolar bone resorption or fracture or even facial paralysis, etc., which need to be analyzed specifically. 1. Loose teeth: If root cysts are not treated in time, it may lead to loosening of the tooth and neighboring teeth due to the inflammation of the cyst affecting the tooth root, or even falling off. 2. Alveolar bone resorption: If the root cyst is not treated in time, it may lead to alveolar bone resorption and alveolar bone fracture due to the inflammation of the cyst affecting the alveolar bone, which will increase the difficulty of subsequent treatment. 3. Facial paralysis: If the root cyst is not treated in time, it may lead to facial paralysis and other abnormal symptoms due to the inflammation spreading to the surrounding facial nerve. Untreated root cysts may also cause other consequences, it is recommended that once the patient found his root cysts, timely access to the doctor to improve the relevant examination, standardized treatment.
