I had some cyst type thing in my lower lips area just above lower lips under mouth, have visited one dentist but he was not sure but still said that It was perhaps Mucocele and he gave HEXIGEL but in spite of using it for 1 week still mucocele is not remove completely. It goes off completely and comes back again, this happened 4 times in last 10 days. So, whether mucocele can be treated via medicine and is there any risk that it can lead to cancer?
