Hi gang and thank you for your thoughts. Years ago I did indeed have a whiteish coating on my tongue so I know that Candida may have been a factor in the past. Over the years I have also periodically used Diflucan 200 mg /day on various occasions (generally for a month at a time).

However, although at the moment my tongue looks complete normal with no coating, I may give the Oragel a try.

Given my small-fiber issues over time I naturally thought (perhaps incorrectly then) that the small-fiber neuropathy might have spread to my mouth.
