The signal can even be diluted by well-meaning people. For example, Washington did have a set of teeth that included those of slaves. However, his financial records include the purchase of teeth from "Negros" for the purpose, which at the very least indicates he didn't have someone hold his own slaves down and rip teeth out of their heads. It doesn't preclude there being an element of racism and abuse in the path those teeth took from their origin to their purchase by Washington, but it does show there may not have been, and that Washington wearing slave teeth is not a mark against him personally. The whole "owning slaves" thing is of course, but that's a separate issue from the dentures.
