hi mam, doing braces treatment twice doesn't exposure dentin. you must did the self diagnosis for your self.
1 . sensitive teeth
2. enamel de calcification during orthodontic treatment due to poor oral hygiene ( most common cause after orthodontic treatment)
can be re mineralized to some level. deep de calcification requires filling / veneer / crown.
All the best for happy smiling
