Poor dental health is a leading cause of absenteeism.

"Poor oral health can have a detrimental effect on children’s quality of life, their performance at school, and their success later in life.2 Tooth decay is preventable and ensuring that students have the preventive oral health services they need in school is important in helping them stay healthy and ready to learn. Dental sealants prevent tooth decay and also stop cavities from growing—they result in a large reduction in tooth decay among school-aged children 5–16 years of age."
