My wife has tried Orbit chewing gum during the day and it seems to calm it down. Nights are the worst, she tried the gum while sleeping but you might run the risk of swallowing it. She tries to stick it on the back of the front upper teeth and that works most of the times.

I was lucky to have a daughter who is a nurse. She gave me a solution that numbs the tongue for about 30 minutes. It is Lidocaine. It is like a gell that coats your tongue when it is stinging, The stinging or burning has changed my life. I can see why people that have this become socially isolated, then become depresssed, and then they need cognitive therapy. Every time you go somewhere there is always food and drink. I find that this sometimes sets off the burning. I can only hope that they come up with a cure in 2025. I have gone everywhere and the doctors just don't know how to treat this. Hope this helps.
