text: reappearing of whitish tissue even after removing white tissue epitheliual dysplasia severe  reasons     e? doctor oral pathologist and dental surgeon took biopsy and found in one section epithelial dysplasia severe comment---though there is no evidence of frank invasion in the submitted tissuses it is suggested that the entire lesion be excised and examined to rule out malignancy.  accordingly he did surgery and almost the entire lesion removed fron the lower gum and sent for biopsy. to check the surrounding tissus are normal and not dysplastic. it may take 3 days. the doctor says after the tissues are healed  which may take 3 weeks put another denture. till then not to use any denture. now whether this dysplastic will further spread  and create problems and how to prevent it. doctor already removed the entire lesion and did surgery.he says not to worry what is you opinion and precautions to be taken at this stage. i am not happy that he removed "almost" the entire lesion, since this was supposed to be an excisional biopsy, but i was not there and do not know the conditions that exist in your mouth.  perhaps it was very close to the mental foramen and he did not want to leave you permamnently numb if it is not necessary.  this dysplasia is very likely in response to a poor fitting denture.  it's not unlike the callous you have on your elbow.  just let the surgical site heal for a few weeks (as recommended) and then either get a new denture or have your existing denture relined (if it is otherwise suitable) so that it fits properly.  at this stage, just don't wear your denture until it heals and be careful not to bump into the area with any food if you are chewing soft foods.
