The orthodontic retainer is often the last step in an orthodontic procedure, to ensure the teeth stay in place after braces or surgery. Each retainer is a perfect representation of the individual’s palette, similar to a fingerprint. The teeth will otherwise seek to return to their native state. The majority of people who undergo a retainer fitting are adolescents, and therefore the retainer can be seen as a 3-dimensional snapshot of the individual’s mouth from just before the brink of adulthood. It is a relic of the doorway to adult life, manufactured by way of one of the body’s most intimate orifices.
