I only remember a episode I’m pretty sure it was Japanese animated or something in one episode they go inside a persons tooth and find it’s infected with a swarm of black things and a queen that looked like a anime girl wearing all black and with wings after destroying them they remind the person to brush they’re teeth and another person was brushing they’re teeth beside them and then it turns out they’re tooth hurts and then they all look at her and the episode ends this tv show was in color and idk where it’s from or when it was made but I loved it as a child and I want to find it again.
