EAT YO ORANGES, GUYS.
Diseases of Infancy and Childhood. Louis Fischer, 1912.
When kids get scurvy before their milk teeth or adult teeth come in, it typically arrests the development and/or eruption of teeth. However, when kids haven’t had scurvy for more than a few months (at which point the tooth buds tend to end up very damaged or killed), having delayed development and eruption of their teeth is actually a better outcome (dentally) than getting it as an adult.
When adults get scurvy, the gum tissue and teeth roots are some of the first affected tissues. Having very loose teeth makes it easy to lose them, even if they don’t fall out on their own initially. After the scurvy is dealt with, the adult often ends up with missing teeth.
With kids, though, tooth development and eruption resumes as normal as soon as Vitamin C is reintroduced into the diet. If the scurvy was not present for long enough to damage the tooth buds, they will end up with normal teeth as an adult, though the permanent teeth do come in significantly later in life than in a healthy child.
