Lola... I didn't have braces one of our other members had chronic irritation from braces. I have been concerned with the side I chew on as well. I had two molars there that were irritating my tongue so I had them filed down a bit and that has solved the problem. if I'm a little irritated there (crackers and such and chewing hard stuff can cause this - also spicy acidic foods as you may know) anyway when I'm a little irritated there is switch to soft non irritating foods for a few days until its gone.

This is considered a new primary for you - best of luck with everything thankfully they've caught it early hugs!
