National Tooth Fairy Day is observed on February 28 of every year. National Tooth Fairy Day is a day to look back on the history of dental care’s little helpers and to encourage our children to develop proper dental hygiene. Kids love the excitement of waking up to a gift from a fairy in exchange for a lost tooth. It’s a fun myth, who wouldn’t like it!? It’s just as fun for the parents and adults also. Some parts of the world, it is also celebrated on August 22.
