What do you suggest if my ex-gf's bulimia has returned. how can i help her?

Doable: She does need to see a psychotherapist and perhaps soon after a psychiatrist . Most times a referral is needed and you could help by attending the initial evaluation with her. Good chance the support and assurance she would feel as highly encouraging to do the treatment . Take care

To reduce damage to teeth during vomiting the use of clear retainers and a baking soda ‘retainer gel’ will reduce the contact of stomach acid to the teeth. The act of preparing may also aid in reducing the act and should be combined with professional therapy.
