This is a different expert, with a different answer.
I would like to answer the questions you have asked.
There is no established reason that the blunt dentures [please tell me exactly what you have, brand, etc] would play a part.
In theory, some materials can evoke sensitivity [autoimmune] in some individuals. Like I said, in theory but we can talk more about this.
We do not diagnose on line.
As far as the GI possibilities. You need an exam.
These are not typical symptoms of diverticulosis, but it is possible.
Irritable bowel, other bowel problems are possible, including various problems of inflammation.
If you have not had a clean colonoscopy [I assume they did one five years ago?] in the last 10 years, this would be indicated.
Otherwise, much different testing which we can go over.
