Dental Hygiene Kits

I currently am living in China and teaching English to 96 of the cutest kids! They have not been taught proper dental hygiene and I want to help them start learning how to take care of their teeth. Please help me in ordering dental kits for them so they can start bettering their teeth. We will be working with the school to help them understand the importance of keeping their teeth clean so that as they lose their baby teeth they already have healthy habits. I love these kids so much and your help is greatly appreciated!
