My niece, nephew, and I enjoyed Throw Your Tooth on the Roof. My niece and nephew both liked learning about what kids from various countries/cultures do with their teeth when they fall out, and my nephew, like me, was fascinated by how many cultures believe in a "Tooth Mouse" rather than a Tooth Fairy. Really, just the kind of book that curious little kids are apt to enjoy--it is, after all, a story about them and a pretty big rite of passage in their lives.
I also found the book interesting from an adult perspective. Many of the South American countries believe in a "Tooth Mouse," as does Spain. Canada, the United States, and Australia believe in a tooth fairy, as does England. Not only is Throw Your Tooth on the Roof a story of lost teeth and the now-what-do-I-do-with-this-thing aftermath, it is a story of colonization as evidenced through beliefs and traditions.
I also loved that a lot of unexpected nations were examined here. Mauritania, Denmark, Tajikistan, Benin, Bangladesh, Cambodia, just to name a very few. The author also took pains to address some native or aboriginal beliefs, among them Navajo, Aboriginal Australians, and Maori, and where differences exist between urban and rural beliefs in a single nation, the author presented both.
Throw Your Tooth on the Roof was a well done book, and it has inspired my niece to try throwing her next lost tooth on the roof of her house. The Tooth Fairy might enjoy a night off.
