I am getting help and I am recovering, however I do slip up sometimes. I was bulimic for 3 months before my friends made me get help. Month seven and I slip up occasionally. I used to throw up only once a day, if I did at all. I’ve heard it takes 3 years for damage to your teeth will show but then other say it is sooner within months even. I get no straight answer because they are all different. When would a dentist see visual signs of erosion?
