The mucous cyst usually when left alone will resolve spontaneously in 3 – 4 weeks. It may burst leaving an ulcerated surface which will heal after sometime.
If the cyst returns or fails to regress on its own, then you have to consult the doctor. Avoid chewing and sucking on these cysts when present and never attempt to break the cyst at home as it can result in infection.
A minor surgery may be indicated in recurrent cases where the contents and the lining of the cyst may be removed.
Other advanced treatments options include laser surgery, cryosurgery and injecting medicine inside the lesion.
