my teeth are SO screwed

i only started purging like a month ago (maybe a month and a half) and i used to restrict before that the thing is i haven't even LOST any weight but my teeth are yellow and i used to have "perfect" (i don't like that they're called perfect that isn't how it works but yeah straight and white) teeth other than maybe staining from CAFFEINE but now ??? i'm so scared because my mom's a dentist she'll definitely know and also they don't grow back this can't be fixed it's not worth it none of this is worth it but i can't STOP
