I've been bulimic for about a year and a half, purging three to four days a week on average (sometimes more, sometimes less if it's a good week). I went to the dentist and, since my last cleaning just six months ago, I have developed FOUR cavities. The dentist was surprised and assumed I drank tons of soda or ate tons of candy. I just couldn't bring myself to admit to him the truth of the whole situation. It was such a rude awakening. I have always thought that this couldn't happen to me because I haven't been bulimic for that long. And I also have taken all the necessary steps to preserve my teeth, like swishing with water and chewing on cheese or antacids afterwards. I just wanted to share my bulimia teeth issues. This because I don't want anyone on this site to convince themselves, as I have been doing, that they won't ruin their teeth and their bodies. Because you will eventually, and it could happen as quickly as it has for me.
