D.F.
Usually around 3. When the child has all of their molars and teeth in. They don't clean their teeth at their first appointment. They just get them familiar with the dentist chair and staff. The dentist will look at the teeth though. The 2nd appointment is cleaning and flossing (if the child let's them). The staff tries their best to make it a fun experience (not a scary one). You have plenty of time.
