National Give Kids a Smile Day is observed on the first Friday in February and aims to provide essential dental care to underserved children in the United States. Established in 2002 by two dentists in St. Louis, Missouri, the initiative has grown to include events across the country, sponsored by the American Dental Association. The day focuses on ensuring children receive necessary oral health care, as millions go without it, leading to issues with sleeping, eating, and school performance. Typical customs include hosting community events where dental professionals offer free services, making donations to support dental clinics, and educating children about proper dental hygiene. Activities may also involve reading books about dental health to children to alleviate their fears about visiting the dentist.
