Throughout Sharp Objects, we learn more and more about the importance of Ann Nash and Natalie Keene’s teeth being pulled. Was it truly a male that committed these murders because it is so difficult to pull the teeth out of a child’s mouth? We know that Ann Nash and Natalie were young girls but it can be assumed they had their adult teeth. Their 6 year molars likely came in as these girls were old enough to be playing with Amma, Kelsey, Jodes and Kylie who were all around 13 years old.
It might be a slight lack of research by Gillian Flynn to assume that these girls did not have their adult teeth. That said, it is still much easier to extract a tooth at a younger age versus when the roots have fully grown in by adulthood. Oral surgeons, dentists and dental professionals will likely be the only ones that will catch this mistake.
