Sarki,
sorry you are having problems, I am afraid I know what you are going thru. I was recommended to Biotene products, they do help some, but nothing is perfect. I think
some of the meds I take for allergy are the worst culprits, but can't function without them.
I recently quired a partial plate that has made life a lot drier. I wear it when I go out or visit, but can't deal with the dry feeling on a regular basis.

Be ever so careful about infection in the bad teeth...I know how the hubby can hit the
roof over things like this, but landing in the hospital with osteomeylitis wouldn't thrill
him much more. And any MS symptoms can be aggravated by infection or stress caused
by dental pain.

Good luck, k
