[|Human|] I have just had a piece of tissue removed from upper gum due to bad fitting dentures a large mass of excess tissue has grown,  dentist wants to biopsy it before going ahead and removing it all. He put in some stiches and said they would dissolve. I am worried because of language barrier, I am in Taiwan. I am healthy 50yrs old woman. any help would be great.  Thanks
[|AI|]  Thanks for using Chat Doctor. Read your query. Excess tissue growth with ill-fitting denture as you have described is usually harmless referred as Ellis fissuratum. This is usually cause by chronic tissue irritation by an ill-fitting dentures and its response to the soft tissue. Biopsy is usually done to rule out any other lesions including neoplasm. I would suggest you to go ahead with surgical removal of the tissue. After the healing get a new denture done with proper fitting and proper maintenance of the denture. Hope this was useful. Thanks and regards.
