Hi dear, The mucus cyst can occur due to various reason like biting , accidental rupture of salivary gland , adjacent teeth causing chronic damage or cheek biting . It has no connection with shakes . Treatment is based upon the severity of the mucous cyst. Sometimes cysts may not require treatment and will heal on their own over time. Superficial cysts heal in very short times . But there are other treatment options available for severe cysts like laser therapy , cryotherapy and intralesional corticosteroid injection . So i would suggest you to consult oral surgeon for proper treatment . D octor may use a scalpel or laser to remove the salivary gland. Local anesthesia numbs the pain. Marsupialization is also one of the treatment option. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
