The Smiley Train is a beautifully illustrated publication on orthodontic care designed for children 7 and 8 years old—the age at which the American Association of Orthodontists (AAO) recommends that parents schedule their child's initial orthodontic evaluation. The Smiley Train is an exclusive service for your orthodontic practice. No other orthodontic practice in your patient area is eligible to participate. Each publication is customized with your practice's logo and contact information, making it a unique educational resource that also promotes your practice.
