teeth are rotting out of my head

i’m so upset.

background, i have ehlers danlos (maybe related.) and have always struggled with my teeth. cavities since i can remember. but also horrible mental health. couldn’t hardly brush my teeth for years. finally last year got most of it filled and fixed— majority of my teeth have fillings. i’ve started brushing every day and floss when i can remember.

i’ve found a giant hole in my tooth, and a couple other smaller ones. what am i doing wrong? i dont want to lose my teeth. i’m so sad. i’m doing everything i can to take care of them but im still ending up with cavities. root canals scare me so bad, ive already had one. i don’t want to have another one. i dont want to have dentures or implants. i want MY teeth. i’ve tried so hard. i’ve fought with MDD and BPD, ive fought to better myself. to take better care of myself. but i’m still being punished.
