How long does it take for bulimia to affect your teeth?

See doctor: This depends on how frequently you are purging yourself. But you can quickly do serious damage to your teeth. See a doctor for help with your bulimia asap.

Bulimia: One of my patients has this disorder, has done significant damage to her teeth and is in her mid 20's. Needless to say it does not take long for some people.

Not long: Not too long. You need to seek medical care as soon as possible. The acid from your stomach will erode the teeth and make them fragile.

Bulimia: Unfortunately it starts right away, similar to food on teeth starting cavities. It's dependent upon the length of time the purged material is in contact with the teeth. Rinse thoroughly right away but do not brush of floss for 30 minutes as there is residual acid that can erode tooth enamel. I hope that you are either under professional care or seeking help. Good luck and best wishes.
