Here is the link to the article: https://www.mountvernon.org/george-washington/health/washingtons-teeth/george-washington-and-slave-teeth/#-
The author of the article seems to conclude that this arrangement was common and voluntarily between President Washington and the unnamed enslaved persons, but I am not sure I entirely buy that portrayal. Is this something that commonly happened and were enslaved people voluntarily participating in the practice or were they likely coerced (directly or indirectly)?
/u/uncovered-history has previously answered Is there any truth to this article claiming George Washington's false teeth were taken from his slaves? but may see fit to elaborate.
