Dr. Castillo only did a quick count of the teeth as my kids were screaming/upset. It was hard to do the exam, but felt it would have been better if she had more time.

I was surprised by how quick it was to clean Olivias teeth but I was also relieved as children have a very short attention span! My biggest worry was, how long is she going to cooperate in the dentist chair. She did really well! We love her!
