I had suffered from (BMS) for almost a year and was really mad because I could not eat my favorite spicy food any more along with salsa on my tacos (LOL). Oh well those days are gone after much research and seeing several good doctors.
I know how annoying this desease or infection what ever it may be is to anyone and I have searched the internet and have not seen a definitive answer as to how to cure it.
SO thats where I come in. The answer is BAKING SODA thats right BAKING SODA!
The last doctor I saw recommended me to rinse my mouth with 1/2 cup of water and add 1 1/2 tablespoons of baking soda mix and rinse. Rinse 3 times a day
Make sure you dont eat anything spicy or anything that will iritate your tongue or infected area for atleast a week.
When the pain from BMS has settled down a bit what you do is put a little bit of toothpaste on your toothbrush and then sprinkle BAKING SODA on top so it covers it then with your brush, brush all that BAKING SODA into infected area
If done properly and you take care for at least a week and doing rinsing & brushing 3 times a day you might have the same result as me, being able to enjoy spicy food once again, and aliviate yourself from the harsh pain of Burning Mouth Syndrome I hope this helps
