In the final cut it was changed to one of her tooth falling out. In a earlier version according to a storyboard, her gums would bleed. The scene that shows Lynn brushing her teeth was modified in the final cut.This is hinted to be a joke because the show is rated TV-Y7 and TV-G on Google Play Movies and TV (now Google TV) and cursing or adult material is not permitted to this series. This could be innuendo within the episode based on not to use foul language. The audio of Lily cursing at the end of episode 'Potty Mouth' is bleeped out.The episode was pulled from airing in 2020 due to the plot of the flu zombies relating to COVID-19.The episode was pulled from airing in 2020 due to being paired with One Flu Over the Loud House.This could be possibly a brief swearing joke and not actual cursing.
