Sandradee 

Dear Sandradee,

Here are a few links to the things I’ve tried that really have helped.  

All available from Boots the Chemist (in store or online).

Dry Mouth:

Biotène Toothpaste:

Biotène Mouthwash

And these Oralieve products do a similar thing.

Painful or sore mouth (e.g. mouth ulcers etc):

Difflam

Kindest as ever.

Thank you so much for the information. Much appreciated.
