Excellent to read before a first dentist visit.
I thought this would be a good book to help get my toddler ready for a visit to the dentist, but I was disappointed in the book content--Zack spends too much time being disrespectful, lying, and just generally naughty. I thought the content about the actual dentist visit was very minimal. I would recommend looking at this book at the library before deciding if it is something you want to own.
