I've been having trouble with mint, too! I had radiation and chemo for tongue cancer in Jan 2024. Since the a variety of foods bother my tongue. My saliva production is pretty good. But anything mint burns. Mayonnaise is like fire! Sugar, too. Any beer or wine burns, too. I read about the acid vs alkaline balance and started using baking soda. While recovering from cancer I used a lot of baking soda rinse. I stopped that once I was healed. I've now gone back to that and its helped a bit with the stinging. I also take a 1/4 tsp in water and swallow it twice a day. It has stopped the general mouth/tongue burning.
