My daughter has ADHD and ODD. ODD is Oppositional Defiance Disorder. She can be quite the handful at times. I was dreading taking her to the dentist and expected the worst.The hygienist, Jessi, was AMAZING in handling my daughter. She was able to be firm and effective, but not offensive. We had a great experience with NO melt downs or tears from my daughter. My daughter wants to go back!
