I was bulimic for six years and have luckily had minimal damage due to constant dental care. However, I do have discoloration and my teeth are very sensitive. I brush with Sensodyne and I have to wear a mouth guard at night because I grind my teeth and have chipped a couple of teeth before. I had to get rid of my tongue ring as well because it was scraping off some of the enamel on the backs of my teeth. If anything, the damage I have endured from bulimia is very severe acid reflux that I have to take a prescription medication for, and a very sensitive gag reflex.
