We all seem to have this primal fear when it comes to losing a tooth. Is it instinctual? Evolutionary? Regardless, Ian gets to the very root (hehe) of this fear with "Dental Plan." It made me empathize with the rather smarmy narrator, which I didn't want to do, and a few times I resisted the urge to reach for my own teeth to ensure they were still securely in place. The action and suspense build nicely, and at the end, it left me sufficiently creeped out and fascinated by what had just transpired. A worthy read!
