I was always told a year old as well. I took my daughter when she was 18 months and it was horrible. The dentist was great, but my daughter was not ready. I held her and she still cried. The dentist could not even do a cleaning so I paid $75.00 for her to tell me lets try in another 6 months. I brush her teeth twice a day and floss at night the dentist said that was great and her teeth looked great. I also make sure to brush her teeth when she has had anythign sweet to eat. You know your daughter better than anyone so if you think she can sit still and have them clean her teeth then I would take her, but if not just wait make sure to brush her teeth as often as you can and floss at night she will be fine until she gets a little older.
