Hi there....long time no see!

1) Burning mouth or other mouth irritations can be from
an ingredient in mouth washes, and toothpaste....it is called
Triclosan. New studies show it causes nerve damage.
There is a post about it on Myasthenia Gravis forum...so search there. And several posts on General forum and Introductions forum. Use our search function to find those.
I am sorry but I just cannot do that for you today.

2). B12 is the next culprit...low levels are connected to burning mouth.

3) As Dr. Smith has posted, lipoic acid can be helpful.

I recall finding a really good dental site with other suggestions, and I posted to a newbie about a year ago giving it. So use the search function to find that excellent article.

Sometimes burning mouth can be traced to certain food intolerances. Seafood, spices etc are the most common. But any food you are intolerant of can do it.

If you reflux in the night with GERD...it can burn your mouth too.
Excessive or regular vomiting will do it too.

Take care... I am leaving Sat morning, and won't be back for 5 weeks for my vacation in the wilds of the North!
