What causes a specific itch in the gums?

I have had this itch for over 20 years and no dental professional can explain nor do anything for me. I sometimes create a bad sore in my mouth trying to "scratch" it.

What causes a specific itch in the gums?
Your problem may be emotional or related to a neurological issue. While you may think it's uncommon, it's not. There are numerous reasons the condition exists. It could be related to a medication you have taken for years, or it could be an alergic reaction to a type of dental material that has been placed in your mouth. I had a patient who suffered similar issues for many many years and all I had supplied him was a new Lower denture replacement for an older one as he had all his Upper natural teeth. I had him tested for Diabetes and it turned out he was a Diabetic, which he didn't realize. I then made him a new denture created from a very old type material called "Vulcanite", which is actually a material made from rubber. Within a week following getting the new Vulcanite denture the mouth problems went away. Some diabetics have allergic reactions to dental materials, especially plastics. This of course is just one possible scenario. As for the emotional issue, people do have emotional stress issues that create a variety of presentations. What you describe is one possibility. Emotional Stress is created from problems relating to one or a combination of the following issues, Money, Marriage, Employment, Health, Sex and Self Esteem......Stress is like a bad appendix, it seldom ever heals itself by it self. A doctor or professional counselor is most often needed to deal with either or both and getting that help is a vast sign of intelligence, ignoring it is ....well, I needn't have to point that out. I wish you well and please look at all your options.
