This is gonna sound weird but the teeth in the game are one of the coolest subtle storytelling features that are easily overlooked. By 1899: toothbrushes, cavity fillings, nitrous oxide, and dental schools all existed. Of course it wasn’t something that was too commonplace, particularly for outlaws, you can see a stark contrast between the “society people” and the gang. For example, Molly and Mary Linton both have straight, white teeth; meanwhile characters like Charles have jagged, yellowed teeth. Charles in particular didn’t have any access to dental care due to poverty, isolation, and racial discrimination. The character that the teeth really shine as a story telling element is Dutch. Dutch dresses well, properly trims his facial hair, but his teeth are yellowing and have noticeable gaps. Despite his presentation as a leader and a messiah to the gang, his teeth are just another example that Dutch is just an outlaw like the rest of the gang.
