I have a mentally disabled sister iq 36. she has had lifelong dental care. she had masactomy abour 14yrs ago being reassured that she would not need chemo or radiology. it returned close to the surface & has broken thru the skin 2 yrs ago. it is very slow growing. i think she is near the end. She doesn t understand what is wrong. She cannot communicate or direct Dr s to the pain. mainly she communicates that her finger hurts. Up until a couple of months ago she had her teeth professionally cleans every 3 mos She is in hospice & lives in a nursing home, but this last bout of cancer we decided not to put her thru the treatment. Her teeth have begun to turn black at the root & fall out. She points to her mouth but doesn t acknowledge if there is pain. She is nauseated. The do not have an oncologist to question Is there anything u can tell me as to whatelse to look forward to. She is very frail. Her meals are puree . My main question is: Now that her teeth have bleckened near the gum, & are falling out. Now close is the end?
