First dentist appointment

So.. my daughter is 23 months. She’s never been to the dentist. No one ever told me when she should go first. Her pediatrician retired last year with pretty much no notice, and we are having a hell of a time finding a new one as we live in an area where they either don’t take our insurance or have horrible reviews. Plus, they haven’t given us her records so no one wants to see her. Anyways, my family says the first appointment should be when they get all their teeth, which she doesn’t have them all, but has a lot. And other members are saying I’m a horrible mother for not taken her yet. I’m a first time mom, had her at 16 so no one really taught me anything about this. So.. when did you guys take your kids? Am I a bad mom?
