Skin in my mouth?

Does anyone get a huge amount of skin peeling off in their mouth?
It is usually in the lining on all the inner lip and gums? I tend to have it every several months at a time which last for over 2weeks. I do not believe it has to do with me changing my toothpaste as I have been using Sensodyne for years now.

I have not had the routine skin peeling yet but it usually does tend to start during winter season.

Below is a picture of my skin from my mouth. Sometimes the skin in my mouth is very long; peeled from one side to the other side of my mouth.
